Abstract
Hereditary breast and ovarian cancer syndrome (HBOC) resulting from pathogenic variants of BRCA1 or BRCA2 is the most common and well-documented hereditary tumor. Although founder variants have been identified in population-based surveys in various countries, the types of variants are not uniform across races and regions. Recently, the Tohoku Medical Megabank Organization (ToMMo) released whole-genome sequence data including approximately 54,000 individuals from the general population of the Tohoku area in Japan. We analyzed these data and comprehensively identified the prevalence of BRCA1/2 pathogenic and truncating variants. We believe that an accurate understanding of the unique distribution and characteristics of pathogenic BRCA1/2 variants in Japan through this analysis will enable better surveillance and intervention for HBOC patients, not only in Japan but also worldwide.

Abstract
BACKGROUND Accumulating evidence has demonstrated platinum-based chemotherapy followed by maintenance therapy with a poly Adenosine diphosphate (ADP)-ribose polymerase inhibitor (olaparib) show benefits in unresectable pancreatic cancer with a germline (g)BRCA1/2 mutation. Evaluation of the germline BRCA1 and BRCA2 mutation is essential for making decisions on a treatment strategy for patients with unresectable pancreatic cancer. However, the detection rates of germline BRCA1 and BRCA2 mutations and efficacy of maintenance with olaparib remain undetermined, prospectively, in Japan. METHODS & RESULTS In this prospective analysis, the rate of germline BRCA1 and BRCA2 mutations and efficacy of chemotherapy were analyzed in 136 patients with pancreatic cancer who underwent BRACAnalysis® (85 patients) or FoundationOne® CDx (51 patients) between January 2020 and July 2022. A total of six patients (4.4%) had a germline BRCA1 and BRCA2 mutation. Five patients were treated with modified FOLFIRINOX and one with fluorouracil and oxaliplatin. All patients continued platinum-based chemotherapy for ˃4 months and were subsequently treated with olaparib as a maintenance therapy. The response rate to platinum-based chemotherapy in the germline BRCA1 and BRCA2 mutation-positive group was significantly better than that of the germline BRCA1 and BRCA2 mutation-negative group (66% vs 23%, P = 0.04). All patients harbouring a germline BRCA1 and BRCA2 mutation were able to switch to olaparib. The median progression-free survival using olaparib was 5.7 months (range 3.0-9.2). CONCLUSIONS The rate of germline BRCA1 and BRCA2 mutations found in patients with unresectable pancreatic cancer was comparable to those of previous studies.An analysis of germline BRCA1 and BRCA2 mutations has benefits for all patients with unresectable pancreatic cancer with regard to decisions on therapeutic strategies in a clinical practice setting.

Abstract
A 26-year-old man presented with a tumor in the left soleus muscle. The tumor was diagnosed as a locally advanced leiomyosarcoma. The patient was treated with irradiation followed by wide resection. One year after surgery, the patient presented with multiple lung metastases. Despite aggressive sequential chemotherapy, systemic metastatic tumors continued to develop. To explore therapeutic options for the patient, we performed DNA-based CGP with FoundationOne® CDx (F1). F1 identified anout-of-strand rearrangement of the NOS1AP::NTRK1 gene, which has not been previously reported. In contrast, RNA sequencing revealed an in-frame LMNA::NTRK1 gene, which is an oncogenic fusion gene.

Abstract
Comprehensive genomic profiling (CGP) tests have been covered by public insurance in Japan for patients with advanced solid tumors who have completed or are completing standard treatments or do not have them. Therefore, genotype-matched drug candidates are often unapproved or off-label, and improving clinical trial access is critical, involving the appropriate timing of CGP tests. To address this issue, we analyzed the previous treatment data for 441 patients from an observational study on CGP tests discussed by the expert panel at Hokkaido University Hospital between August 2019 and May 2021. The median number of previous treatment lines was two; three or more lines accounted for 49%. Information on genotype-matched therapies was provided to 277 (63%). Genotype-matched clinical trials were ineligible because of an excess number of previous treatment lines or use of specific agents were found in 66 (15%) patients, with the highest proportion in breast and prostate cancers. Many patients met the exclusion criteria of one to two or more treatment lines across cancer types. In addition, previous use of specific agents was a frequent exclusion criterion for breast, prostate, colorectal, and ovarian cancers. The patients with tumor types with a low median number (two or fewer) of previous treatment lines, including most rare cancers, primary unknown cancers, and pancreatic cancers, had significantly fewer ineligible clinical trials. The earlier timing of CGP tests may improve access to genotype-matched clinical trials, with their proportion varying by cancer type. Each relevant society needs to advocate the desirable timing of CGP testing nationwide.

Abstract
OBJECTIVE Xq chromosome duplication with complex rearrangements is generally acknowledged to be associated with neurodevelopmental disorders, such as Pelizaeus-Merzbacher disease (PMD) and MECP2 duplication syndrome. For couples who required a PGT-M (pre-implantation genetic testing for monogenic disease) for these disorders, junction-specific PCR is useful to directly detect pathogenic variants. Therefore, pre-clinical workup for PGT-M requires the identification of the junction of duplicated segments in PMD and MECP2 duplication syndrome, which is generally difficult. METHODS In this report, we used nanopore long-read sequencing targeting the X chromosome using an adaptive sampling method to identify breakpoint junctions in disease-causing triplications. RESULTS By long-read sequencing, we successfully identified breakpoint junctions in one PMD case with PLP1 triplication and in another MECP2 triplication case in a single sequencing run. Surprisingly, the duplicated region involving MECP2 was inserted 45 Mb proximal to the original position. This inserted region was confirmed by FISH analysis. With the help of precise mapping of the pathogenic variant, we successfully re-established STR haplotyping for PGT-M and avoided any potential misinterpretation of the pathogenic allele due to recombination. CONCLUSION Long-read sequencing with adaptive sampling in a PGT-M pre-clinical workup is a beneficial method for identifying junctions of chromosomal complex structural rearrangements.

Abstract
Characterization of the genomic landscape of biliary tract cancer (BTC) may lead to applying genotype-matched therapy for patients with this disease. Evidence that comprehensive cancer genomic profiling (CGP) guides genotype-matched therapy to improve clinical outcomes is building. However, the significance of CGP in patients with BTC remains unclarified in clinical practice. Therefore, the purposes of this study were to assess the utility of CGP and identify associations between clinical outcomes and genomic alterations in patients with BTC. In this prospective analysis, detection rates for actionable genomic alterations and access rates for genotype-matched therapy were analyzed in 72 patients with advanced BTC who had undergone commercial CGP. Cox regression analyses assessed relationships between overall survival and genomic alterations detected with CGP. The most common genomic alterations detected were TP53 (41, 56.9%), followed by CDKN2A/B (24, 33.3%/20, 27.8%), and KRAS (20, 27.8%). Actionable genomic alterations were identified in 58.3% (42/72) of patients. Detection rates for FGFR2 fusions, IDH1 mutations, and BRAF V600E were low in this cohort. Eight (11.1%) patients received genotype-matched therapy. For patients with intrahepatic cholangiocarcinoma (ICC), CDKN2A/B loss was associated with shorter overall survival. These real-world data demonstrate that CGP can identify therapeutic options in patients with advanced BTC. CDKN2A/B loss was identified as a poor prognostic factor in patients with ICC. Thus, this study provides a rationale for considering CGP in planning therapeutic strategies for advanced BTC.

Abstract
BACKGROUND When considering BRCA1/2 genetic testing for diagnosis of hereditary breast and ovarian cancer (HBOC), family history (FH) of breast and ovarian cancer is commonly considered. However, FH of other HBOC-related cancers, such as prostate, pancreatic, and skin cancer (malignant melanoma), is often overlooked. METHODS Among 945 patients who received genetic testing of BRCA1/2 at our hospital between October 2010 and September 2021, we compared the FH of 123 patients diagnosed with HBOC and 669 other patients who had breast cancer and had a documented FH. This study focused on the FH of HBOC-related cancers such as breast, ovarian, prostate, pancreatic, and skin cancer, as well as colorectal, gastric, liver, lung, and uterine cancers, which are common among Japanese, and other cancers. RESULTS FH of prostate, pancreatic, and skin cancer was significantly higher in the BRCA2 pathogenic variant (PV) cases than in the wild-type (WT) cases. The mean number of family members are as follows: BRCA1 PV/ BRCA2 PV/ WT; prostate cancer: 0.05/ 0.34/ 0.09 (P < 0.0001, Kruskal-Wallis multiple comparisons test), pancreatic cancer: 0.13/ 0.21/ 0.10 (P = 0.01637), and skin cancer: 0.03/ 0.07/ 0.01 (P = 0.00129), respectively. CONCLUSIONS When considering BRCA1/2 genetic testing, FH of prostate, pancreatic, and skin cancers may also be examined as HBOC-related cancers to provide testing for patients who would benefit from it. However, further studies for the association between skin cancer and HBOC will be required because it has not been reported in Japan.

Abstract
About 4 and a half years have passed since"Cancer Genome Medicine"was first mentioned in the Third Phase of the Basic Plan to Promote Cancer Control Programs that started in October 2017. Currently, cancer genomic medicine is being carried out by the cancer gene panel test, which is covered by public insurance, mainly at the 12 Cancer Genome Medicine Core Center Hospital designated nationwide by the Ministry of Health, Labor, and Welfare in Japan. Cancer genomic medicine has come to be positioned as a standard medical treatment. However, there are various challenges in operating an expert panel that professionally examines the results of the gene panel tests and reports treatment recommendations and secondary findings that suggest hereditary tumors. In addition, there is an urgent need to disseminate and educate healthcare professionals and patients about cancer genomic medicine. In this panel discussion on January 14, 2022, 10 panelists discussed how to solve these issues and the prospects for the future.

Abstract
INTRODUCTION An X-linked ZC4H2 variant is associated with a variety of phenotypes that have abnormalities related to external malformation and neurodevelopment. There have been no reports on severe respiratory dysfunction resulting in surgical treatments not being possible due to the deformity resulting from in this disease. Here we report a female with arthrogryposis multiplex congenita with a severe respiratory complication. CASE A two-year-old girl had arthrogryposis multiplex congenita at delivery and subsequently had hypotonia and feeding difficulty. A novel ZC4H2 frameshift variant was identified by whole-exome sequencing in her genome. At eight months, she had recurrent aspiration pneumonia. A tracheostomy and gastrostomy were required; however, surgical intervention was not possible because of her short neck and complicated airway. CONCLUSION We compared this case with previous reports. The truncation group had more described phenotypes than the non-truncation group. The patient had the most severe respiratory dysfunction in truncating variant.

Abstract
The Hokkaido medical personnel training plan connecting humans and medicine aims to train"Medical personnel for genome medicine"," Medical personnel for rare cancer and childhood cancer", and"Medical personnel who promote cancer measures according to patient's life stage". We have worked on preparing medical professionals who undergo training courses not only in the graduate school but also in the community medicine centers cooperating with central medical centers in Hokkaido. Furthermore, we have been committed to training medical staff who provide comprehensive healthcare for patients with cancer cross-regionally, cross-sectionally, and tumor-agnostically and researchers who can pursue genome medicine. The evaluation committee concluded that the plan was substantially advanced according to the evaluation guideline, and a committee member commented that the information through Web was assessable during the COVID-19 pandemic; in fact, it should be ensured by everyone. Based on these comments, we continuously work to develop human resources using content and information dissemination know-how accumulated in the Hokkaido medical personnel training plan.

Abstract
BACKGROUND Neuroendocrine neoplasm (NEN) is a comparatively rare tumor that has been considered indolent. Due to these characteristics, detailed epidemiological data have not been analyzed in Japan. To elucidate the present status of NEN diagnosis and treatment in Japan, we started a registry cohort study in January 2015. METHODS Patients pathologically diagnosed with NENs of the pancreas, gastrointestinal tract, lungs, bronchi, or thymus after January 2012 were enrolled in this registry after the date of ethics review committee approval in each hospital or institute. Follow-up was continued for enrolled patients. RESULTS During 5 years of enrollment between January 2015 and December 2019, a total of 1526 participants from 63 departments were enrolled in this registry (mean, 305.2 participants/year), covering approximately 5.8% of the annual incidence of NENs in Japan. For pancreatic NEN, 41.9% of patients had metastasis and the dominant metastatic site was the liver, at twice the rate of lymph node metastasis in the current registry. In contrast, the frequency of lymph node metastasis from gastrointestinal (GI)-NEN was similar to that of the liver. The distribution of WHO 2019-based grades varied according to the primary site. Low-to-intermediate grade (G1-G2) was dominant for duodenal, jejunal/ileal, rectal, and pancreatic NENs, whereas high grade (G3 or NEC) was dominant for esophageal, stomach, and colon NENs. For PanNENs, G3 and NEC accounted only for 1.6% and 2.9%, respectively. CONCLUSIONS These cohort data provide crucial information for clinical research to clarify the characteristics of NENs in Japan.

Abstract
Ehlers-Danlos syndrome is a rare genetic disorder that presents with a variety of pathologies depending on the disease type. Among them, vascular Ehlers-Danlos syndrome requires extremely careful management as there have been many reports of fatal perinatal complications such as uterine rupture. Although hypermobile Ehlers-Danlos syndrome is less likely to cause fatal complications, symptoms such as arthralgia, hip dislocation, and depression may be seen throughout pregnancy. We report here a case of twin pregnancy in which Ehlers-Danlos syndrome was first suspected at 19 weeks of gestation. Vascular Ehlers-Danlos syndrome could not be ruled out based on family medical history, making it difficult to determine the perinatal management strategy. Prompt genetic testing did however rule out the vascular type and the patient was diagnosed with hypermobile Ehlers-Danlos syndrome from the clinical symptoms, enabling us to manage the pregnancy safely until 34 weeks of gestation. In the case of twin pregnancy reported, Ehlers-Danlos syndrome was suspected at 19 weeks of gestation. Vascular-type Ehlers-Danlos syndrome could not be ruled out based on family medical history. Twin pregnancies with vascular-type Ehlers-Danlos syndrome have a high maternal risk of mortality. Prompt genetic testing enabled us to manage the pregnancy safely.

Abstract
Neuroendocrine neoplasms (NENs) are rare neoplasms that occur in various organs and present with diverse clinical manifestations. Pathological classification is important in the diagnosis of NENs. Treatment strategies must be selected according to the status of differentiation and malignancy by accurately determining whether the neoplasm is functioning or nonfunctioning, degree of disease progression, and presence of metastasis. The newly revised Clinical Practice Guidelines for Gastroenteropancreatic Neuroendocrine Neoplasms (GEP-NENs) comprises 5 chapters-diagnosis, pathology, surgical treatment, medical and multidisciplinary treatment, and multiple endocrine neoplasia type 1 (MEN1)/von Hippel-Lindau (VHL) disease-and includes 51 clinical questions and 19 columns. These guidelines aim to provide direction and practical clinical content for the management of GEP-NEN preferentially based on clinically useful reports. These revised guidelines also refer to the new concept of "neuroendocrine tumor" (NET) grade 3, which is based on the 2017 and 2019 WHO criteria; this includes health insurance coverage of somatostatin receptor scintigraphy for NEN, everolimus for lung and gastrointestinal NET, and lanreotide for GEP-NET. The guidelines also newly refer to the diagnosis, treatment, and surveillance of NEN associated with VHL disease and MEN1. The accuracy of these guidelines has been improved by examining and adopting new evidence obtained after the first edition was published.

Abstract
Multiple endocrine neoplasia type 2B (MEN2B) is an extremely rare disease, most often
caused by a de novo p.Met918Thr RET mutation. Medullary
thyroid carcinoma of MEN2B has a good prognosis if diagnosed by one year of age. However,
diagnosis of MEN2B within the first year of life is markedly challenging owing to its high
de novo occurrence and lack of clarity in terms of extra-endocrine
symptoms that could aid early diagnosis. Herein, we present six cases of Japanese children
with MEN2B harboring the p.Met918Thr RET variant. Exploratory data
extraction was conducted using a questionnaire. The patients underwent thyroidectomy at a
median age of 11 yr (range, 6–19 yr). Four of the six patients underwent neonatal
hospitalization at birth without complications, and three tested positive for
neuroblastoma screening at infancy. The patients presented at least one MEN2B-associated
symptom before one year of age, including ganglioneuromas, pseudo-Hirschsprung disease,
alacrima, bumpy lips, sucking disability, or decreased muscle tone, along with other
suspected comorbidities, such as Williams or Prader–Willi syndrome. This case series
demonstrates that MEN2B manifests through several extra-endocrine symptoms by the age of
one year.

Abstract
Objective Little is known about the time from developing a first cancer to confirming the presence of a mismatch repair (MMR) gene mutation for Lynch syndrome (LS) probands. Methods This was a retrospective single center study. LS probands, who have an MMR gene mutation that was confirmed first in a pedigree and thereafter developed at least one cancer, were included in this study. Results There were 21 LS probands who had developed at least one cancer; 6 with MLH1 mutations, 9 with MSH2 mutations, 4 with MSH6 mutations, and 2 with EPCAM deletions. The median ages at the first cancer and the genetic diagnosis were 47 (34-71) and 62 (38-84) years old, respectively. The mean interval between the first cancer and the genetic diagnosis was 11.0 (0-25) years, and 20 years or longer interval was required for the 5 probands. Six (28.6%) probands were older than 70 years, and 3 (14.3%) were in their 80s when they were diagnosed to have LS. The genetic diagnosis was confirmed at the first, second, third, and fourth cancer or later in 5, 5, 6, and 5 probands, respectively. Of the 16 cancers examined, 2 (12.5%) were microsatellite stable (MSS), both of whom had germline MSH6 mutations. All 17 LS probands who developed colorectal cancer met the revised Bethesda guidelines at the genetic diagnosis, but only 7 of 11 (63.6%) met them at the first cancer. Twelve out of 21 (57.1%) met the revised Amsterdam criteria. Conclusion It took 11 years for the LS probands from the first cancer to the diagnostic confirmation by genetic tests. A quarter of the probands were in their 70s or 80s at genetic diagnosis.

Abstract
BACKGROUND Comprehensive cancer genomic profiling has been used recently for patients with advanced solid cancers. Two cancer genomic profiling tests for patients with no standard treatment are covered by Japanese public health insurance since June 2019. METHODS We prospectively analyzed data of 189 patients with solid cancers who underwent either of the two-cancer genomic profiling tests at Hokkaido University Hospital and its liaison hospitals and whose results were discussed in molecular tumor board at Hokkaido University Hospital between August 2019 and July 2020. RESULTS All 189 patients had appropriate results. Actionable gene alterations were identified in 93 patients (49%). Frequent mutations included PIK3CA (12%) mutation, BRCA1/2 alteration (7%), ERBB2 amplification (6%) and tumor mutation burden-High (4%). The median turnaround time from sample shipping to acquisition by the expert panel was 26 days. Although 115 patients (61%) were provided with information for genotype-matched therapies, only 21 (11%) received them. Notably, four of eight patients below the age of 20 years were provided information for genotype-matched therapies, and three received them. Their response rates and disease control rates were 29% and 67%, respectively. Most patients who did not undergo the genotype-matched therapies were provided information for only investigational drugs in phases I and II at distant clinical trial sites in central Japan. Twenty-six patients were informed of suspected germline findings, while 11 patients (42%) received genetic counseling. CONCLUSIONS The publicly reimbursed cancer genomic profilings may lead to the modest but favorable therapeutic efficacy of genotype-matched therapy for solid cancer patients with no standard therapy. However, poor access to genotype-matched therapy needs to be resolved.

Abstract
BACKGROUND Chromodomain helicase DNA-binding (CHD) proteins play important roles in developmental processes. CHD3, a member of the CHD family of proteins, was reported to be a cause of a neurodevelopmental syndrome by Snijders Blok et al., but only a small number of probands have been reported. CASE REPORT The patient was a 9-year-old female with severe intellectual disability, speech impairment, autism, joint laxity and dysmorphisms. Whole exome sequencing revealed a de novo missense variant in CHD3 (NM_001005273:exon18: c.2896C > T:p.R966W). CONCLUSION We report a case with a pathogenic variant in the CHD3 gene. Our report indicates that CHD3 analysis is helpful for diagnosis of the cases with neurodevelopmental disorders, joint laxity, and coarse facial phenotype.

Abstract
Symmetries are well known to have had a profound role in our understanding of nature and are a critical design concept for the realization of advanced technologies. In fact, many symmetry-broken states associated with different phases of matter appear in a variety of quantum technology applications. Such symmetries are normally broken in spatial dimension, however, they can also be broken temporally leading to the concept of discrete time symmetries and their associated crystals. Discrete time crystals (DTCs) are a novel state of matter emerging in periodically driven quantum systems. Typically, they have been investigated assuming individual control operations with uniform rotation errors across the entire system. In this work we explore a new paradigm arising from nonuniform rotation errors, where two dramatically different phases of matter coexist in well defined regions of space. We consider a quantum spin network possessing long-range interactions where different driving operations act on different regions of that network. What results from its inherent symmetries is a system where one region is a DTC, while the second is ferromagnetic. We envision our work to open a new avenue of research on chimeralike phases of matter where two different phases coexist in space.

Abstract
BACKGROUND Hereditary diffuse gastric cancer (HDGC) is a familial cancer syndrome often associated with germline mutations in the CDH1 gene. However, the frequency of CDH1 mutations is low in patients with HDGC in East Asian countries. Herein, we report three cases of HDGC harboring a missense CDH1 variant, c.1679C>G, from a single Japanese family.
CASE SUMMARY A 26-year-old female (Case 1) and a 51-year-old male (father of Case 1), who had a strong family history of gastric cancer, were diagnosed with advanced diffuse gastric cancer. After genetic counselling, a 25-year-old younger brother of Case 1 underwent surveillance esophagogastroduodenoscopy that detected small signet ring cell carcinoma foci as multiple pale lesions in the gastric mucosa. Genetic analysis revealed a CDH1 c.1679C>G variant in all three patients.
CONCLUSION It is important for individuals suspected of having HDGC to be actively offered genetics evaluation. This report will contribute to an increased awareness of HDGC.

Abstract
Background The prognostic nutritional index (pni) is a simple metric calculated using serum albumin and the peripheral lymphocyte count. It was reported that a low pni score is significantly associated with major postoperative complications and poor prognosis. The purpose of the present study was to investigate the effects of perioperative oral management (pom) on the perioperative pni profiles of patients with digestive system or urinary cancers. Study Design The medical records of 181 patients with cancer who underwent surgery and for whom a pni could be calculated were retrospectively reviewed. Results The intervention rate with pom was 34.8%. The median preoperative pni score was 48.25 in all patients with a pom intervention [25% to 75% interquartile range (iqr): 44.38-54.13] and 47.25 in those without an intervention (iqr: 42.0-53.5). Compared with patients not receiving pom, those who received pom had significantly higher pni scores from the early postoperative period (p < 0.05). Notably, of patients who could resume oral intake within 3 days after surgery, those who received pom intervention, compared with those who did not, had significantly higher pni scores from the early postoperative period (p < 0.05). Conclusions Perioperative oral management interventions might have positive effects on the postoperative pni scores of patients with cancer.

Abstract
SIGNIFICANCE The responsible genetic variants for occult macular dystrophy (OMD) were found at the predicted intrinsically disordered region (IDR) of the RP1L1 gene. PURPOSE We examined the phenotypes and genotypes of family members from OMD. In addition, the genetic characteristics of the RP1L1 gene in OMD were investigated. METHODS Whole-exome sequencing was applied on two affected family members, and Sanger sequencing was performed on three members. The structural property of RP1L1 and pathogenic variants was analyzed using predictor of natural disordered regions (PONDR). RESULTS Two affected members showed moderate visual impairment and relative central scotoma. The spectral domain optical coherence tomography (SD-OCT) images showed an absence of the interdigitation zone (IZ) and ellipsoid zone (EZ) in one case, and an obscure EZ line in the other case. A RP1L1 variant (c.3593 C > T, p.Ser1198Phe) was identified in two affected members but not in the unaffected member. The PONDR analysis showed that the region from p.1189 to p.1248 could be predicted to be an IDR in the RP1L1 molecule. And the p. Ser1198Phe variant showed significant reduction of PONDR score. CONCLUSIONS Although, the major pathogenic variant of OMD is p.Arg45Trp, multiple reports indicate that the region between p.1194 and p.1201 is another hot spot of OMD. The PONDR analysis predicted that the RP1L1 molecule is one of the intrinsically disordered proteins. It is speculated that the region around p.1200 is essential for the normal function of the RP1L1 molecule, and the missense variants of that area cause the development of OMD.

Abstract
OBJECTIVE Multiple endocrine neoplasia type 2A (MEN 2A) is a rare syndrome caused by RET germline mutations and has been associated with primary hyperparathyroidism (PHPT) in up to 30% of cases. Recommendations on RET screening in patients with apparently sporadic PHPT are unclear. We aimed to estimate the prevalence of cases presenting with PHPT as first manifestation among MEN 2A index cases and to characterize the former cases. DESIGN AND METHODS An international retrospective multicenter study of 1085 MEN 2A index cases. Experts from MEN 2 centers all over the world were invited to participate. A total of 19 centers in 17 different countries provided registry data of index cases followed from 1974 to 2017. RESULTS Ten cases presented with PHPT as their first manifestation of MEN 2A, yielding a prevalence of 0.9% (95% CI: 0.4-1.6). 9/10 cases were diagnosed with medullary thyroid carcinoma (MTC) in relation to parathyroid surgery and 1/10 was diagnosed 15 years after parathyroid surgery. 7/9 cases with full TNM data were node-positive at MTC diagnosis. CONCLUSIONS Our data suggest that the prevalence of MEN 2A index cases that present with PHPT as their first manifestation is very low. The majority of index cases presenting with PHPT as first manifestation have synchronous MTC and are often node-positive. Thus, our observations suggest that not performing RET mutation analysis in patients with apparently sporadic PHPT would result in an extremely low false-negative rate, if no other MEN 2A component, specifically MTC, are found during work-up or resection of PHPT.

Abstract
We generated three disease-specific iPSC lines from a Multiple endocrine neoplasia type 1 (MEN1) patient and three control iPSC lines from an unaffected blood relative of the patient using unutilized lymphoblastoid B cell lines (LCLs) as a cell resource. The expression of pluripotency markers, retaining of normal karyotype of chromosome, absence of episomal vectors used for generating the iPSCs and EBV used for generating LCLs, and the potential to differentiate into three germ layers, were confirmed for each iPSC line. These iPSC lines can be useful for construction of the disease models in vitro, and elucidation of the disease mechanisms.

Abstract
CONTEXT von Hippel-Lindau disease, comprising renal cancer, hemangioblastoma and/or pheochromocytoma (PHEO) is caused by missense or truncating variants of the VHL tumor suppressor gene, which is involved in degradation of hypoxia inducible factors (HIFs). However, the role of synonymous VHL variants in the disease is unclear. OBJECTIVE We evaluated a synonymous VHL variant in patients with familial PHEO or VHL disease without a detectable pathogenic VHL mutation. DESIGN We performed genetic and transcriptional analyses of leukocytes and/or tumors from affected and unaffected individuals and evaluated VHL splicing in existing cancer databases. RESULTS We identified a synonymous VHL variant(c.414A>G, p.Pro138Pro) as the driver event in five independent individuals/families with PHEOs or VHL syndrome. This variant promotes exon 2 skipping and, hence, abolishes expression of the full-length VHL transcript. Exon 2 spans the HIF binding domain, required for HIF degradation by VHL. Accordingly, PHEOs carrying this variant display HIF hyperactivation typical of VHL loss. Moreover, other exon 2 VHL variants from the TCGA pan-cancer datasets are biased toward expression of a VHL transcript that excludes this exon, supporting a broader impact of this spliced variant. CONCLUSION A recurrent synonymous VHL variant (c.414A>G, p.Pro138Pro) confers susceptibility to PHEO and VHL disease through splice disruption, leading to VHL dysfunction. This finding indicates that certain synonymous VHL variants may be clinically relevant and should be considered in genetic testing and surveillance settings. The observation that other coding VHL variants can exclude exon 2 suggests that dysregulated splicing may be an underappreciated mechanism in VHL-mediated tumorigenesis.

Abstract
The human noggin (NOG) gene is responsible for a broad spectrum of clinical manifestations of NOG-related symphalangism spectrum disorder (NOG-SSD), which include proximal symphalangism, multiple synostoses, stapes ankylosis with broad thumbs (SABTT), tarsal–carpal coalition syndrome, and brachydactyly type B2. Some of these disorders exhibit phenotypes associated with congenital stapes ankylosis. In the present study, we describe a Japanese pedigree with dactylosymphysis and conductive hearing loss due to congenital stapes ankylosis. The range of motion in her elbow joint was also restricted. The family showed multiple clinical features and was diagnosed with SABTT. Sanger sequencing analysis of the NOG gene in the family members revealed a novel heterozygous nonsense mutation (c.397A>T; p.K133*). In the family, the prevalence of dactylosymphysis and hyperopia was 100% while that of stapes ankylosis was less than 100%. Stapes surgery using a CO2 laser led to a significant improvement of the conductive hearing loss. This novel mutation expands our understanding of NOG-SSD from clinical and genetic perspectives.

Abstract
Introduction An accurate differential diagnosis between single adenoma (SA) and multiglandular disease (MGD) remains difficult in Technetium-99m sestamibi scintigraphy (MIBI)-negative patients with primary hyperparathyroidism (PHPT). The aim of the present study was to evaluate the minimally invasive parathyroidectomy (MIP) in patients with PHPT. Methods Clinical records of 48 patients who underwent neck exploration between November 2002 and June 2012 in Kochi Medical School Hospital were reviewed retrospectively to identify candidates that underwent for MIP which was defined as the selective removal of a SA using less invasive surgery. Results The preoperative detection rate of lesions using ultrasonography, MIBI, computed tomography, and magnetic resonance imaging was 90%, 83%, 76%, and 55%, respectively. Although all 39 patients in the MIBI-positive group were diagnosed with an SA and subsequently underwent curative MIP, 3 patients in MIBI-negative group (n = 6) were MGD, who underwent neck exploration. Preoperative mean intact parathyroid hormone (419 pg/ml vs. 149 pg/ml; P < 0.01) and alkaline phosphatase levels (746 U/l vs. 277 U/l; P < 0.01) were significantly higher in the SA than MGD group. Conclusions In MIBI-negative patients with indications for surgery, MIP should not be carried out without a clear localization of SA, or in MGD. We examined diagnostic accuracy for 48 patients with primary hyperparathyroidism. All 39 patients in the MIBI-positive group were diagnosed with a single adenoma. The preoperative diagnostic accuracy in MIBI-negative patients was only 50%. We advise minimally invasive parathyroidectomy is avoided in MIBI-negative patients.

Abstract
A 13-yr-old boy who complained of persistent nausea, vomiting and weight loss had
hypercalcemia and an elevated intact PTH level. Computed tomography confirmed two tumors
in the thyroid gland. The tumors were surgically removed and pathologically confirmed as
parathyroid adenoma. Because his maternal aunt and grandmother both had histories of
parathyroid tumors, genetic investigation was undertaken for him, and a germline
frameshift mutation of the CDC73 gene was identified.
CDC73 gene analysis should be done on individuals who are at risk of
familial hyperparathyroidism, including those who are asymptomatic, and they should be
followed for potential primary hyperparathyroidism and associated disorders including
resultant parathyroid carcinoma.

Abstract
Hyperparathyroidism-jaw tumor syndrome (HPT-JT) is a rare autosomal dominant hereditary tumor syndrome characterized by synchronous or metachronous occurrence of primary hyperparathyroidism (PHPT), ossifying fibroma of the maxilla and/or mandible, renal tumor and uterine tumors. Early diagnosis of this syndrome is essential because it is associated with increased risk of parathyroid cancer. A 30-year-old man with urolithiasis had severe hypercalcemia (15.0 mg/dL after correction) induced by inappropriate parathyroid hormone (PTH) secretion (intact PTH 1390 pg/mL), indicating severe PHPT. An underlying parathyroid tumor was surgically removed and was histologically confirmed to be an adenoma. However, PHPT due to another parathyroid tumor reoccurred two years after the surgery. Although no HPT-JT-associated manifestations other than PHPT were detected, HPT-JT was strongly suspected based on the exclusion of multiple endocrine neoplasia (MEN) and the young age of disease occurrence. Genetic analysis revealed a novel nonsense mutation (p.Arg91X; c.271C>T) in exon 3 of the causative gene, CDC73, which encodes the tumor suppressor protein parafibromin. The residual parathyroid glands were all removed without autotransplantation of parathyroid gland taking into consideration prospective parathyroid carcinogenesis. The resected parathyroid tumor was also an adenoma. The present case highlights that HPT-JT should be considered and CDC73 mutation analysis should be performed, especially in cases of early-onset PHPT, recurrent PHPT, PHPT with polyglandular parathyroid involvement, and PHPT presenting with severe hypercalcemia even if there is no positive family history.

Abstract
No long-term exercise training regimen with high adherence and effectiveness in middle-aged and older people is broadly available in the field. We assessed the adherence to, and effects of, our long-term training program comprising an interval walking training (IWT) and an information technology network system and the factors affecting adherence. Middle-aged and older men and women [n = 696, aged 65 ± 7(SD) yr] underwent IWT. The subjects were instructed to repeat five or more sets of fast and slow walking for 3 min each at ≥70 and 40% peak aerobic capacity for walking (V̇O2peak), respectively, per day ≥4 days/wk for 22 mo. Adherence was assessed as training days accomplished relative to the target of 4 days/wk over 22 mo. The effects on the V̇O2peak and lifestyle-related disease score were evaluated every 6 mo. The independent factors affecting adherence were assessed by multiple-regression analysis after adjustment for baseline physical characteristics and other possible covariates, including vasopressin V1a receptor polymorphisms. The adherence over 22 mo averaged 70% and was highly correlated with a 13% reduction in the lifestyle-related disease score (R(2) = 0.94, P = 0.006) and with a 12% increase in V̇O2peak (R(2) = 0.94, P = 0.006). The major determinant of higher adherence was lower baseline body mass index (BMI) (P < 0.0001) and male sex (P < 0.0001). For men, in addition to BMI, nonsmokers (P = 0.031) and V1a receptor polymorphisms (P = 0.033) were independent determinants of higher adherence. Thus the long-term IWT program is an effective regimen. Moreover, baseline BMI and sex for all subjects, and smoking and V1a receptor polymorphisms for men, were associated with adherence.

Abstract
Heatstroke is considered an important condition that may contribute to endothelial cell damage. The aim of this study was to assess temporal profiles of the cytokine (IL-6 and IL-8) and mRNA production when endothelial cells undergo higher temperature stimuli. In the first group, human umbilical vascular endothelial cells (HUVECs)were cultured at 4 different temperatures (37, 38, 39 or 40 degrees C) for 1, 3 and 5 h. In the second group, HUVECs were cultured at 37 degrees C for 4 h or 23 h, after stimulation by heating for one hour at the same culture temperatures used in the first group (37 degrees C to 40 degrees C). After culturing, IL-6 and IL-8 mRNA and protein levels were measured. It has been found the cytokine mRNA levels being significantly higher (p < 0.001) in all cells incubated at higher temperatures than those in the control (cultivation at 37 degrees C). At the same time, the productionof IL-6 and 8 at a higher temperature (39, 40 degrees C) was significantly lower (p < 0.001) than at 37 degrees C (control), and the decrease was temperature dependent. However, IL-6 and IL-8 levels were significantly greater in the cells at 23 h after transient hyperthermic (40 degrees C, 1 h) stimulation than in control ones (p < 0.001).After a transient hyperthermia, the production of the cytokines in HUVECs is initially inhibited and then augmented. The results indicated that tissue injury might continue to develop after a hyperthermic event. There might be a potent risk for underestimation of cytokine induced tissue injury in the acute phase of a heatstroke.

Abstract
Measuring the levels of the plasma free metanephrines (PFMs) represents a recently developed and promising test for the diagnosis of pheochromocytoma in the United States and Europe. As this test has not yet been evaluated in Japan, it is necessary to evaluate the diagnostic efficacy of measuring the levels of PFMs compared with the standard measurement of the urinary excretion of metanephrines (uMNs) whose reliability is well established to detect of pheochromocytoma. A total of 101 Japanese subjects clinically suspected of having pheochromocytoma in were included in this study. Subsequently, we prospectively measured the PFMs levels in all patients, compared with those of biochemical markers of the catecholamine secretion and metabolisms in the plasma and urine. All subjects with adrenal tumors underwent tumor excision. Data were available for 84 of the 101 patients, 47 of whom had histopathologically proven pheochromocytoma and 37 were finally diagnosed with non-pheochromocytoma. The results of comparisons in the accuracy of measurement for diagnosis of pheochromocytoma between PFMs and the urinary excretion of metanephrines (uMNs) were 0.980 VS 0.951 for AUC of receiver operatorating characteristic (ROC) curve, 0.957 VS 0.894 for sensitivity, and 0.973 VS 0.946 for specificity, respectively. Although the differences were small, the results of our study definitely demonstrated that measurement of PFMs was not inferior to standard urinary metanephrines (uMNs) measurement, which is established to be the most reliable biochemical method to detect pheochromocytoma. This study clearly shows measuring the PFMs levels to be a reliable and efficient method for diagnosing pheochromocytoma in Japanese patients, as demonstrated in previous reports.

Abstract
A 38-year-old woman with a thyroid nodule measuring approximately 2 cm was suspected to have medullary thyroid carcinoma (MTC) because of markedly elevated serum calcitonin and carcinoembryonic antigen levels. There were no signs of pheochromocytoma, whereas primary hyperparathyroidism was suspected based on the findings of inappropriate hypersecretion of parathyroid hormone although no parathyroid tumor was detected with imaging studies. RET mutation analysis revealed a novel germline missense mutation in codon 666, c.1997A>G (p.K666R). She underwent total thyroidectomy with lymphadenectomy and simultaneous total parathyroidectomy with autotransplantation of parathyroid tissue. She was given calcium lactate and alfacalcidol to prevent postoperative hypocalcemia. Pathological findings of the thyroid tumor were compatible with MTC, but the resected parathyroid glands were intact. To our knowledge, c.1997A>G (p.K666R) is a new RET mutation. This is a minor variant, but it is significant because of the possible pathogenicity in tumor formation. It is often difficult to determine whether MTC is generated as part of MEN2-related disease or familial MTC when it is a unique manifestation. In addition, it is still unclear whether all missense mutations in this codon reported previously will lead to the same clinical course and prognosis. Further careful observations of clinical presentation are required to determine the clinical features associated with this variant.

Abstract
BACKGROUND AND PURPOSE GLA is the causative gene of Fabry disease, an X-linked lysosomal storage disorder resulting from α-galactosidase A (α-GAL) deficiency. Stroke is an important manifestation of Fabry disease, and recent epidemiological studies have indicated that up to 4.9% of young male cryptogenic stroke patients have GLA mutations. To determine the importance of GLA mutations in the general stroke population, the frequency of GLA mutations in Japanese male ischaemic stroke (IS) patients with various risk factors and ages was measured. METHODS A total of 475 male IS patients (mean age 69.7 ± 12.5 years), were enrolled in this study. A blood sample was obtained to produce blood spots for measurement of α-GAL activity. Blood samples with decreased enzymatic activity were reassayed and the entire GLA gene was analyzed by direct DNA sequencing if α-Gal A activity was consistently low. RESULTS α-Gal A activity was decreased in 10 men, five of whom (1.1%) had the GLA gene mutation, p.E66Q. All IS patients with p.E66Q mutation had substantial residual α-Gal A activity, in contrast to patients with classic-type Fabry disease. Clinically, all patients with p.E66Q mutation were > 50 years old and had multiple small-vessel occlusions (lacunar infarctions). Statistical analysis using Fisher's exact test showed the allele frequency of GLA p.E66Q in patients with small-vessel occlusion to be significantly higher than that in the general Japanese population [odds ratio (OR) = 3.34, P = 0.025). CONCLUSIONS GLA p.E66Q mutation is a genetic risk factor for cerebral small-vessel occlusion in elderly Japanese males.
