Biallelic missense CEP55 variants cause prenatal MARCH syndrome. J Hum Genet 2024:10.1038/s10038-024-01298-7. [PMID: 39414989 DOI: 10.1038/s10038-024-01298-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2024] [Revised: 09/04/2024] [Accepted: 09/26/2024] [Indexed: 10/18/2024]
Abstract
CEP55 encodes centrosomal protein 55 kDa, which plays a crucial role in mitosis, particularly cytokinesis. Biallelic CEP55 variants cause MARCH syndrome (multinucleated neurons, anhydramnios, renal dysplasia, cerebellar hypoplasia and hydranencephaly). Here, we describe a Japanese family with two affected siblings harboring novel compound heterozygous CEP55 variants, NM_001127182: c.[1357 C > T];[1358 G > A] p.[(Arg453Cys)];[(Arg453His)]. Both presented clinically with typical lethal MARCH syndrome. Although a combination of missense and nonsense variants has been reported previously, this is the first report of biallelic missense CEP55 variants. These variants biallelically affected the same amino acid, Arg453, in the last 40 amino acids of CEP55. These residues are functionally important for CEP55 localization to the midbody during cell division, and may be associated with severe clinical outcomes. More cases of pathogenic CEP55 variants are needed to establish the genotype-phenotype correlation.

[PMID: 38442533 DOI: 10.1016/j.ejogrb.2024.02.054] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2023] [Revised: 02/22/2024] [Accepted: 02/29/2024] [Indexed: 03/07/2024]
Abstract
INTRODUCTION Missed abortion (MA) is a type of miscarriage with multiple etiological factors that refers to fetal death with a failure of the retained intrauterine product of conception to be discharged spontaneously. Currently fetal death in missed abortion is categorized according to three main causes: Fetal, placental, and maternal factors. The aim of the current study was to contribute and increase knowledge in clinical practice of late first and second trimester MA (Gestational age: week 11 + 0 - week 20 + 6). MATERIAL AND METHODS This retrospective case series study includes 794 cases of fetuses and matching placentas sent to the Section of Perinatal Pathology, Department of Pathology, Karolinska Hospital between 2003 and 2019 from five different gynecology departments in the Stockholm region, Sweden. RESULTS The cases were divided into two groups according to gestational length; gestational week 11 + 0-14 + 6 (group A) and 15 + 0-20 + 6 (group B) respectively, and comparisons were made between groups. Fetal growth restriction and placental pathology were more common in late MA, but number of cases with malformation were higher in early MA. Cord pathology was seen in approximately 40 % of the cases and equally distributed in the gestational weeks included. DISCUSSION Fetal growth restriction and placental pathology were more common in late second trimester MA. This might demonstrate an early placental dysfunction affecting fetal growth and may be associated to maternal comorbidity such as autoimmune disease and cardiovascular disease. It is advisable to investigate maternal factors more closely after late second trimester MA before a future pregnancy. The risk for recurrent MA is believed to be low in cases of significant cord pathology. CONCLUSION Cord complications were over-represented in missed abortion suggesting a probable etiopathogenetic link to fetal demise in this condition.

Halo sign in fetal cytomegalovirus infection: cerebral imaging abnormalities and postmortem histopathology in 35 infected fetuses. ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2023; 61:749-757. [PMID: 36730169 DOI: 10.1002/uog.26173] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/21/2022] [Revised: 01/14/2023] [Accepted: 01/19/2023] [Indexed: 06/03/2023]
Abstract
OBJECTIVE To evaluate the correlation of periventricular echogenic halo (halo sign) with histopathological findings and its association with other brain imaging abnormalities in fetuses with cytomegalovirus (CMV) infection. METHODS This was a retrospective study of fetuses diagnosed with severe CMV infection based on central nervous system (CNS) abnormalities seen on ultrasound, which had termination of pregnancy (TOP) or fetal demise at a single center from 2006 to 2021. All included cases had been evaluated by conventional complete fetal autopsy. A maternal-fetal medicine expert reanalyzed the images from the transabdominal and transvaginal neurosonography scans, blinded to the histological findings. The halo sign was defined as the presence of homogeneous periventricular echogenicity observed in all three fetal brain orthogonal planes (axial, parasagittal and coronal). Cases were classified according to whether the halo sign was the only CNS finding (isolated halo sign) or concomitant CNS anomalies were present (non-isolated halo sign). An expert fetal radiologist reanalyzed magnetic resonance imaging (MRI) examinations when available, blinded to the ultrasound and histological results. Hematoxylin-eosin-stained histologic slides were reviewed independently by two experienced pathologists blinded to the neuroimaging results. Ventriculitis was classified into four grades (Grades 0-3) according to the presence and extent of inflammation. Brain damage was categorized into two stages (Stage I, mild; Stage II, severe) according to the histopathological severity and progression of brain lesions. RESULTS Thirty-five CMV-infected fetuses were included in the study, of which 25 were diagnosed in the second and 10 in the third trimester. One fetus underwent intrauterine demise and TOP was carried out in 34 cases. The halo sign was detected on ultrasound in 32 (91%) fetuses (23 in the second trimester and nine in the third), and it was an isolated sonographic finding in six of these cases, all in the second trimester. The median gestational age at ultrasound diagnosis of the halo sign was similar between fetuses in which this was an isolated and those in which it was a non-isolated CNS finding (22.6 vs 24.4 weeks; P = 0.10). In fetuses with a non-isolated halo sign, the severity of additional ultrasound findings was not associated with the trimester at diagnosis, except for microencephaly, which was more frequent in the second compared with the third trimester (10/18 (56%) vs 1/8 (13%); P = 0.04). With respect to histopathological findings, ventriculitis was observed in all fetuses with an isolated halo sign, but this was mild (Grade 1) in the majority of cases (4/6 (67%)). Extensive ventriculitis (Grade 2 or 3) was more frequent in fetuses with a non-isolated halo sign (21/26 (81%)) and those without a periventricular echogenic halo (2/3 (67%); P = 0.032). All fetuses with an isolated halo sign were classified as histopathological Stage I with no signs of brain calcifications, white-matter necrosis or cortical injury. On the other hand, 25/26 fetuses with a non-isolated halo sign and all three fetuses without a periventricular echogenic halo showed severe brain lesions and were categorized as histopathological Stage II. Among fetuses with a non-isolated halo, histological brain lesions did not progress with gestational age, although white-matter necrosis was more frequent, albeit non-significantly, in fetuses diagnosed in the second vs the third trimester (10/15 (67%) vs 3/11 (27%); P = 0.06). CONCLUSIONS In CMV-infected fetuses, an isolated periventricular echogenic halo was observed only in the second trimester and was associated with mild ventriculitis without signs of white-matter calcifications or necrosis. When considering pregnancy continuation, detailed neurosonographic follow-up complemented by MRI examination in the early third trimester is indicated. The prognostic significance of the halo sign as an isolated finding is still to be determined. © 2023 International Society of Ultrasound in Obstetrics and Gynecology.

Age estimation using post-mortem computed tomography and fetal dental radiographic findings in an early to mid-pregnancy fetus: A case report. Leg Med (Tokyo) 2023; 62:102232.

Abstract
Parameters for body size growth are essential to evaluate the relationship between fetal growth and accurate age estimation in forensics. Size values measured postmortem are also affected by the postmortem environment. On the contrary, when using hard tissue maturation criteria, age estimation remains unaffected by the degree of fetal preservation. In Japan, a fetus dying 12 weeks after pregnancy must be reported as a stillbirth. A Japanese stillborn infant buried without reporting to the authorities underwent a forensic autopsy. The gestational age was 4-5 months, based on the mother's description. The body was not fixed, and it was macerated and flattened along the sagittal plane; therefore it was difficult to correctly measure indicators involving soft tissue. The bone size and tooth development were evaluated using postmortem computed tomography (CT) images and intraoral radiography to estimate the age. Considering all the information, including age estimation based on bone sizes referenced in a Japanese study, calcified upper central incisors, we estimated fetal gestational age for our sample as 14-17 gestational weeks finally. However, there were discrepancies between age estimations based on bone size (20-25 gestational weeks, bone radiographic imaging standards; or 4-6 gestational months, an average of the extremity-bones by a Japanese study) and tooth development (14-17 gestational weeks). Deep discussions based on multiple indices with professionals should be applied to forensic age estimation since existing methods may be based on data for different races, use other measurement tools, or apply different sample conditions even if the targets are the same.

Abstract
This study aimed to investigate the correlation between indicators of liver and kidney function and foetal vital organ function. One hundred and eighty-five pregnant women who underwent cordocentesis and whose foetuses were diagnosed with abnormal foetal organ function were enrolled. The indicators of liver and kidney function were compared between foetuses with abnormal vital organ function and healthy foetuses. There was a significant difference between foetuses with and those without normal cardiovascular systems in terms of total protein, albumin, total bile acid, and creatinine levels (P < .05). A significant difference in aspartate aminotransferase (AST) and lactate dehydrogenase (LDH) levels was observed in foetuses with and those without normal foetal urinary systems (P < .05). A difference between foetuses with normal and those without normal musculoskeletal systems was noted when comparing LDH levels. Further, there was a significant difference in gestational age and AST, alanine aminotransferase, albumin, total bilirubin, alkaline phosphatase, LDH, adenosine dehydrogenase, fibronectin, and creatinine levels between foetuses with normal versus abnormal blood systems (P < .05). Thus, hepatic and renal function indicators may be associated with abnormal foetal vital organ function.Impact statementWhat is already known on this subject? Foetal cardiac function is currently evaluated using colour Doppler ultrasound and magnetic resonance imaging in clinical practice, but there are few predictive indicators of the function of other vital organs. It is difficult to determine whether children have abnormalities in the urinary system, digestive system, nervous system, or other vital organs.What do the results of this study add? In this study, it was found that total protein, albumin, total bile acid, creatinine, aspartate aminotransferase, lactate dehydrogenase, fibronectin, alanine aminotransferase, total bilirubin, alkaline phosphatase, adenosine dehydrogenase, and other liver and kidney function indicators may be associated with foetal vital organ dysfunction. However, the forecast range of specific indicators must be further improved upon.What are the implications of these findings for clinical practice and/or further research? This study provides an additional reference for predicting foetal cardiac function.

Villitis of unknown etiology and chronic deciduitis are not associated with human papilloma virus and enterovirus infection. Virchows Arch 2020; 477:73-81. [PMID: 32025822 DOI: 10.1007/s00428-020-02765-0] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2019] [Revised: 01/17/2020] [Accepted: 01/30/2020] [Indexed: 10/25/2022]
Abstract
Villitis of unknown etiology (VUE) and chronic deciduitis with plasma cells (CD) are supposed to be non infectious placental lesions caused by a pathologic immune reaction similar to a host versus graft mechanism. In some investigations, infection of human trophoblastic cells with human papilloma virus (HPV) has been described, and a relationship with miscarriage, preeclampsia, and chronic inflammatory placental lesions has been suspected. Infection with enterovirus, especially Coxsackievirus, has been observed in cases with spontaneous abortion and adverse perinatal outcome, respectively. We investigated 20 cases with VUE and 30 cases with chronic deciduitis with plasma cells. The placenta specimens were analyzed for expression of HPV capsid protein by immunohistochemistry, for presence of HPV DNA via polymerase chain reaction (PCR), and for presence of enterovirus mRNA using RT-PCR, respectively. VUE was associated with maternal diseases: atopic lesions in 21%, other autoimmune diseases in 15.5%, and obesity in 31.5%, respectively. Birth weight below the 10th percentile was detected in 63% of the cases with VUE. Chronic deciduitis was associated with preterm labor and preterm premature rupture of membranes (26%). Intrauterine fetal demise occurred in 5 cases with CD (18.5%). HPV DNA, HPV capsid protein, and enterovirus mRNA were not detected in all investigated VUE or CD cases. Our investigations show that a causal role for enterovirus and human papilloma virus in the development of VUE and CD is unlikely. Therefore, HPV vaccination is unlikely to reduce the incidence of VUE and CD in the future.
