Hu J, Zhang Y, Yang Y, Wang L, Sun Y, Dong M. Case report: Prenatal diagnosis of Kagami–Ogata syndrome in a Chinese family. Front Genet 2022; 13:959666. [PMID: 36035167 PMCID: PMC9410364 DOI: 10.3389/fgene.2022.959666] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2022] [Accepted: 07/14/2022] [Indexed: 11/13/2022] Open
Abstract
The aim of this work was to explore the genetic cause of the proband (Ⅲ2) presenting with polyhydramnios and gastroschisis. Copy number variation sequencing (CNV-seq), methylation-specific multiplex PCR (MS-PCR), and methylation-specific multiplex ligation-dependent probe amplification (MS-MLPA) were used to characterize the genetic etiology. CNV-seq revealed a deletion of 732.26 kb at 14q32.2q32.31 in the proband (Ⅲ2) and its mother (Ⅱ2). MS-PCR showed the maternal allele was missing in the proband, while paternal allele was missing in its mother. MS-MLPA showed deletion of the DLK1, MEG3, MIR380, and RTL1 genes of both the proband and its mother. MEG3 imprinting gene methylation increased in the proband, while decreased in its mother. It was indicated that a maternally transmitted deletion was responsible for Kagami–Ogata syndrome in the proband (Ⅲ2), and the de novo paternal deletion resulted in Temple syndrome in the mother (Ⅱ2). Prenatal diagnosis was provided at 17+3 weeks of pregnancy on the mother’s fourth pregnancy (Ⅲ4). Fortunately, the karyotype and single-nucleotide polymorphism array (SNP array) results were normal. The current investigation provided the detection methods for imprinted gene diseases, expanded the phenotype spectrum of the disease, and obtained the insight into the diagnosis, prenatal diagnosis, and genetic counseling of the disease.

Paternally expressed retrotransposon Gag-like 1 gene, RTL1, is one of the crucial elements for placental angiogenesis in horses†. Biol Reprod 2021; 104:1386-1399. [PMID: 33693478 DOI: 10.1093/biolre/ioab039] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2020] [Revised: 12/08/2020] [Accepted: 03/03/2021] [Indexed: 11/15/2022] Open
Abstract
RTL1 (retrotransposon Gag-like 1) is an essential gene in the development of the human and murine placenta. Several fetal and placental abnormalities such as intrauterine growth restriction (IUGR) and hydrops conditions have been associated with altered expression of this gene. However, the function of RTL1 has not been identified. RTL1 is located on a highly conserved region in eutherian mammals. Therefore, the genetic and molecular analysis in horses could hold important implications for other species, including humans. Here, we demonstrated that RTL1 is paternally expressed and is localized within the endothelial cells of the equine (Equus caballus) chorioallantois. We developed an equine placental microvasculature primary cell culture and demonstrated that RTL1 knockdown leads to loss of the sprouting ability of these endothelial cells. We further demonstrated an association between abnormal expression of RTL1 and development of hydrallantois. Our data suggest that RTL1 may be essential for placental angiogenesis, and its abnormal expression can lead to placental insufficiency. This placental insufficiency could be the reason for IUGR and hydrops conditions reported in other species, including humans.

Abstract
Kagami-Ogata syndrome (KOS) (OMIM #608149) is a genetic imprinting disorder affecting chromosome 14 that results in a characteristic phenotype consisting of typical facial features, skeletal abnormalities including rib abnormalities described as "coat hanger ribs," respiratory distress, abdominal wall defects, polyhydramnios, and developmental delay. First identified by Wang et al in 1991, over 80 cases of KOS have been reported in the literature. KOS, however, continues to remain a rare and potentially underdiagnosed disorder. In this report, we describe two unrelated male infants with differing initial presentations who were both found to have the characteristic "coat hanger" rib appearance on chest X-ray, raising suspicion for KOS. Molecular testing confirmed KOS in each case. In addition to these new cases, we reviewed the existing cases reported in literature. Presence of polyhydramnios, small thorax, curved ribs, and abdominal wall defects must alert the perinatologist toward the possibility of KOS to facilitate appropriate molecular testing. The overall prognosis of KOS remains poor. Early diagnosis allows for counseling by a multidisciplinary team and enables parents to make informed decisions regarding both pregnancy management and postnatal care.

Abstract
INTRODUCTION Kagami-Ogata syndrome (KOS14) and Temple syndrome (TS14) are two disorders associated with reciprocal alterations within the chr14q32 imprinted domain. Here, we present a work-up strategy for preimplantation genetic testing (PGT) to avoid the transmission of a causative micro-deletion. METHODS We analysed DNA from the KOS14 index case and parents using methylation-sensitive ligation-mediated probe amplification and methylation pyrosequencing. The extent of the deletion was mapped using SNP arrays. PGT was performed in trophectoderm samples in order to identify unaffected embryos. Samples were amplified using multiple displacement amplification, followed by genome-wide SNP genotyping to determine the at-risk haplotype and next-generation sequencing to determine aneuploidies. RESULTS A fully methylated pattern at the normally paternally methylated IG-DMR and MEG3 DMR in the KOS14 proband, accompanied by an unmethylated profile in the TS14 mother was consistent with maternal and paternal transmission of a deletion, respectively. Further analysis revealed a 108 kb deletion in both cases. The inheritance of the deletion on different parental alleles was consistent with the opposing phenotypes. In vitro fertilisation with intracytoplasmatic sperm injection and PGT were used to screen for deletion status and to transfer an unaffected embryo in this couple. A single euploid-unaffected embryo was identified resulting in a healthy baby born. DISCUSSION We identify a microdeletion responsible for multigeneration KOS14 and TS14 within a single family where carriers have a 50% risk of transmitting the deletion to their offspring. We show that PGT can successfully be offered to couples with IDs caused by genetic anomalies.

Abstract
The Kagami-Ogata syndrome (KOS) is a rare imprinting disorder with a distinct clinical phenotype. In KOS, polyhydramnios is associated with a small bell-shaped thorax and coat-hanger ribs. The genetic etiology of KOS includes paternal uniparental disomy 14 [upd(14)pat], epimutations, and microdeletions affecting the maternally derived imprinted region of chromosome 14q32.2. More than 77 cases of KOS have been reported; however, only one mosaic upd(14)pat case has been reported. Here we report a second mosaic upd(14)pat case. The prognosis of upd(14)pat patients is poor because of severe respiratory insufficiency. We summarized prenatal ultrasound findings of KOS to raise awareness of this condition for possible diagnosis of KOS prenatally when polyhydramnios combination with a small bell-shaped thorax and other related features are first observed. Prenatal diagnosis using methylation-specific multiplex ligation-dependent probe amplification (MLPA) or a single-nucleotide polymorphism-based microarray analysis is recommended.

Abstract
INTRODUCTION Autosomal recessive polycystic kidney disease (ARPKD; MIM#263200) is one of the most frequent pediatric renal cystic diseases, with an incidence of 1:20,000. It is caused by mutations of the PKHD1 gene, on chromosome 6p12. The clinical spectrum is highly variable, ranging from late-onset milder forms to severe perinatal manifestations. The management of newborns with severe pulmonary insufficiency is challenging, and causes of early death are sepsis or respiratory failure. In cases of massive renal enlargement, early bilateral nephrectomy and peritoneal dialysis may reduce infant mortality. However, there is no conclusive data on the role of surgery, and decision-making is driven by patient's clinical condition and expertise of the center. PATIENT PRESENTATION We hereby describe a preterm female newborn with perinatal, rapid and bilateral, abnormal growth of both kidneys, respiratory failure and initial signs of liver disease. She was subsequently confirmed to be affected by a rare and severe homozygous mutation of the PKHD1 gene, inherited from both her consanguineous parents. Our patient died 78 days after birth, due to a fungal sepsis which worsened her respiratory insufficiency. CONCLUSIONS This patient report shows some of the clinical and ethical issues of neonatal ARPKD, and the need of multidisciplinary approach and good communication with the family. Target next generation sequencing (NGS) techniques may guide and support clinicians, as well as guarantee to these patients the most appropriate clinical management, avoiding unnecessary and/or disproportionate treatments.

Novel LRPPRC compound heterozygous mutation in a child with early-onset Leigh syndrome French-Canadian type: case report of an Italian patient. Ital J Pediatr 2020; 46:140. [PMID: 32972427 PMCID: PMC7517646 DOI: 10.1186/s13052-020-00903-7] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/15/2020] [Accepted: 09/16/2020] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND Mitochondrial diseases, also known as oxidative phosphorylation (OXPHOS) disorders, with a prevalence rate of 1:5000, are the most frequent inherited metabolic diseases. Leigh Syndrome French Canadian type (LSFC), is caused by mutations in the nuclear gene (2p16) leucine-rich pentatricopeptide repeat-containing (LRPPRC). It is an autosomal recessive neurogenetic OXPHOS disorder, phenotypically distinct from other types of Leigh syndrome, with a carrier frequency up to 1:23 and an incidence of 1:2063 in the Saguenay-Lac-St Jean region of Quebec. Recently, LSFC has also been reported outside the French-Canadian population. PATIENT PRESENTATION We report a male Italian (Sicilian) child, born preterm at 28 + 6/7 weeks gestation, carrying a novel LRPPRC compound heterozygous mutation, with facial dysmorphisms, neonatal hypotonia, non-epileptic paroxysmal motor phenomena, and absent sucking-swallowing-breathing coordination requiring, at 4.5 months, a percutaneous endoscopic gastrostomy tube placement. At 5 months brain Magnetic Resonance Imaging showed diffuse cortical atrophy, hypoplasia of corpus callosum, cerebellar vermis hypoplasia, and unfolded hippocampi. Both auditory and visual evoked potentials were pathological. In the following months Video EEG confirmed the persistence of sporadic non epileptic motor phenomena. No episode of metabolic decompensation, acidosis or ketosis, frequently observed in LSFC has been reported. Actually, aged 14 months corrected age for prematurity, the child shows a severe global developmental delay. Metabolic investigations and array Comparative Genomic Hybridization (aCGH) results were normal. Whole-exome sequencing (WES) found a compound heterozygous mutation in the LRPPRC gene, c.1921-7A > G and c.2056A > G (p.Ile686Val), splicing-site and missense variants, inherited from the mother and the father, respectively. CONCLUSIONS We first characterized the clinical and molecular features of a novel LRPPRC variant in a male Sicilian child with early onset encephalopathy and psychomotor impairment. Our patient showed a phenotype characterized by a severe neurodevelopmental delay and absence of metabolic decompensation attributable to a probable residual enzymatic activity. LRPPRC is a rare cause of metabolic encephalopathy outside of Québec. Our patient adds to and broaden the spectrum of LSFC phenotypes. WES analysis is a pivotal genetic test and should be performed in infants and children with hypotonia and developmental delay in whom metabolic investigations and aCGH are normal.

Abstract
Background Persistent neonatal hypoglycemia, owing to the possibility of severe neurodevelopmental consequences, is a leading cause of neonatal care admission. Hyperinsulinemic hypoglycemia is often resistant to dextrose infusion and needs rapid diagnosis and treatment. Several congenital conditions, from single gene defects to genetic syndromes should be considered in the diagnostic approach. Kabuki syndrome type 1 (MIM# 147920) and Kabuki syndrome type 2 (MIM# 300867), can be associated with neonatal hyperinsulinemic hypoglycemia. Patient presentation We report a female Italian (Sicilian) child, born preterm at 35 weeks gestation, with persistent hypoglycemia. Peculiar facial dysmorphisms, neonatal hypotonia, and cerebellar vermis hypoplasia raised suspicion of Kabuki syndrome. Hyperinsulinemic hypoglycemia was confirmed with glucagon test and whole-exome sequencing (WES) found a novel heterozygous splicing-site mutation (c.674-1G > A) in KMT2D gene. Hyperinsulinemic hypoglycemia was successfully treated with diazoxide. At 3 months corrected age for prematurity, a mild global neurodevelopmental delay, postnatal weight and occipitofrontal circumference growth failure were reported. Conclusions Kabuki syndrome should be considered when facing neonatal persistent hypoglycemia. Diazoxide may help to improve hyperinsulinemic hypoglycemia. A multidisciplinary and individualized follow-up should be carried out for early diagnosis and treatment of severe pathological associated conditions.

Early Hum Dev 2020; 141:104945. [PMID: 31901655 DOI: 10.1016/j.earlhumdev.2019.104945] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/05/2019] [Revised: 12/23/2019] [Accepted: 12/24/2019] [Indexed: 12/23/2022]
Abstract
BACKGROUND Congenital pelvic skeletal anomalies (CPSA) may appear as isolated defects or in association with other anomalies like congenital malformations of the digestive system (CMDS). Minor CPSA in non-syndromic patients are often overlooked. We aimed to assess the frequency of CPSA in newborns with CMDS to review the diagnostic approaches. STUDY DESIGN A retrospective review of medical records of 201 newborns who underwent X-rays for different neonatal indications was conducted. In 122 patients CMDS were diagnosed and classified according to the ICD-10 classification; 79 non-CMDS patients acted as controls. Pelvic skeletal segments were examined by X-rays. RESULTS Patients with CMDS, showed a higher risk of CPSA (Odds ratio 2.89; 95% CI 1.34 6.23) and other associated malformations in comparison to non-CMDS patients. Newborns with malformations of the large intestine have the highest risk of adjacent CPSA (48%), as it is a developmental defect originating from the same somite. In addition to skeletal agenesis/hypoplasia, we reported dysmorphic and bifid vertebras, trident ileum, and elongated neural arches. CONCLUSIONS The high incidence of CPSA in CMDS suggests performing a routine radiographic pelvic evaluation in cases of CMDS in order to identify complex phenotypes that could originate from the same developmental field.

Abstract
PURPOSE Recent studies have identified multilocus imprinting disturbances (MLIDs) in a subset of patients with imprinting diseases (IDs) caused by epimutations. We examined MLIDs in patients with Temple syndrome (TS14) and Kagami-Ogata syndrome (KOS14). METHODS We studied four TS14 patients (patients 1-4) and five KOS14 patients (patients 5-9) with epimutations. We performed HumanMethylation450 BeadChip (HM450k) analysis for 43 differentially methylated regions (DMRs) (753 CpG sites) and pyrosequencing for 12 DMRs (62 CpG sites) using leukocyte genomic DNA (Leu-gDNA) of patients 1-9, and performed HM450k analysis for 43 DMRs (a slightly different set of 753 CpG sites) using buccal cell gDNA (Buc-gDNA) of patients 1, 3, and 4. We also performed mutation analysis for six causative and candidate genes for MLIDs and quantitative expression analysis using immortalized lymphocytes in MLID-positive patients. RESULTS Methylation analysis showed hypermethylated ZDBF2-DMR and ZNF597/NAA60-DMR, hypomethylated ZNF597-DMR in both Leu-gDNA and Buc-gDNA, and hypomethylated PPIEL-DMR in Buc-gDNA of patient 1, and hypermethylated GNAS-A/B-DMR in Leu-gDNA of patient 3. No mutations were detected in the six genes for MLIDs. Expression patterns of ZDBF2, ZNF597, and GNAS-A/B were consistent with the identified MLIDs. CONCLUSION This study indicates the presence of MLIDs in TS14 patients but not in KOS14 patients.Genet Med 19 4, 476-482.

Novel microdeletions on chromosome 14q32.2 suggest a potential role for non-coding RNAs in Kagami-Ogata syndrome. Eur J Hum Genet 2016; 24:1724-1729. [PMID: 27406249 DOI: 10.1038/ejhg.2016.82] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2016] [Revised: 05/31/2016] [Accepted: 06/07/2016] [Indexed: 01/08/2023] Open
Abstract
In approximately 20% of individuals with Kagami-Ogata syndrome (KOS14, MIM 608149), characterized by a bell-shaped thorax with coat-hanger configuration of the ribs, joint contractures, abdominal wall defects and polyhydramnios during the pregnancy, the syndrome is caused by a maternal deletion of the imprinted gene cluster in chromosome 14q32.2. Most deletions reported so far included one or both of the differentially methylated regions (DMRs) - DLK1/MEG3 IG-DMR and MEG3-DMR. We present two unrelated families with two affected siblings each, presenting with classical KOS14 due to maternally inherited microdeletions. Interestingly, all four patients have lived through to adulthood, even though mortality rates for patients with KOS14 due to a microdeletion are relatively high. In the first family, none of the DMRs is included in the deletion and the methylation status is identical to that of controls. Deletions that do not encompass the DMRs in this region are thus sufficient to elicit the full KOS14 phenotype. In the second family, a partially overlapping deletion including both DMRs and MEG3 was detected. In summary, we show that patients with KOS14 can live into adulthood, that causal deletions do not have to include the DMRs and that consequently a normal methylation pattern does not exclude KOS14.
