Brain magnetic resonance imaging showed mild atrophic changes. Chromosomal analysis revealed 46, XX, add(18)(q23). Fluorescence in situ hybridization using subtelomere 18q and whole chromosome painting 18 showed subtelomere deletion in 18q, and the add segment was not derived from chromosome 18. Microarray-based comparative genomic hybridization detected a 22 Mb duplication of chromosome 11p15.5p14.3 and a 3.7 Mb deletion of chromosome 18q23. The phenotype of the chromosomal rearrangements is probably resulted from a combination of dosage-sensitive genes.

HMGCL catalyzes the final step of leucine degradation and plays a key role in ketone body formation. Several studies have reported general hepatic findings (e.g., hepatomegaly) in patients with HMGCL deficiency, but currently, there are no available data regarding the incidence and epidemiology of liver involvement. The main objective of our study was to investigate the overall clinical manifestations, laboratory findings, genotype, and presence of hepatic involvement in Saudi patients with HMGCL deficiency. A retrospective chart review of patients with HMGCL deficiency including those with a documented hepatic manifestation was performed at the King Faisal Specialist Hospital & Research Centre in Riyadh, Saudi Arabia. We evaluated 50 cases of HMGCL deficiency. Hepatic findings were found in 17 patients at the time of diagnosis. The mean age of hepatic presentation was 135 days, and the median age was 56 days (range: 2-315 days). Hepatomegaly was found in 65%, abnormal biochemical profile in 47%, and an abnormal imaging in 53% of patients. The most frequent mutation in this cohort was the p.Arg41Gln founder mutation (59%). In comparison to data from the current literature, HMGCL deficiency can be considered as a diagnostic metabolite for hepatic manifestations and requires appropriate evaluation, including molecular genetic analysis.","PeriodicalId":16695,"journal":{"name":"Journal of pediatric genetics","volume":"10 2","pages":"105-110"},"PeriodicalIF":0.4,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1055/s-0040-1714698","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38988424","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The emerging molecular autopsy has added value to post-mortem investigations, where genetic variants were able to explain the unexpected demise. Many of these variants have been found in genes involved in arrythmia pathways. The aim of this study was to sequence 43 genes previously associated with cardiac arrhythmia in a selected cohort of SUDI cases ( n = 19) in South Africa. A total of 335 variants were found among the 19 infants, of which four were novel. The variants were classified as \"likely pathogenic\" ( n = 1), \"variant of unknown significance\" ( n = 54), \"likely benign\" ( n = 56) or \"benign\" ( n = 224). The likely pathogenic variant was LMNA NM_170707.2:c.1279C > T (p.Arg427Cys) and was found in a 3-week-old male infant of African ancestry. Variants in LMNA have previously been associated with dilated cardiomyopathy, with a typical age of onset in adulthood; therefore, this may be the first report in an infant. The yield of pathogenic or likely pathogenic variants in the classic genes typically associated with channelopathies and sudden death, was less in this study compared with other settings. This finding highlights the importance of population-specific research to develop a molecular autopsy which is locally relevant.","PeriodicalId":16695,"journal":{"name":"Journal of pediatric genetics","volume":"11 4","pages":"292-297"},"PeriodicalIF":0.4,"publicationDate":"2021-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9578775/pdf/10-1055-s-0041-1726471.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40562272","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pathogenic genetic variants in the TBX6 gene are one of the causes of CS.

This study employed ES in a cohort of 5 Japanese patients with CS and their healthy parents or a sister for a total of 16 samples among 5 families. Variant interpretation was performed using SIFT, PolyPhen-2, Mutation Taster, and CADD. Four de novo variants were identified by ES and confirmed by Sanger sequencing: 1 frameshift variant ( SHISA3 ) and 3 missense variants ( AGBL5 , HDAC4 , and PDE2A ). ES also uncovered 1 homozygous variant in the MOCOS gene. All of these variants were predicted to be deleterious by SIFT, PolyPhen-2, Mutation Taster, and/or CADD. The number of de novo variants identified in this study was exactly what would be expected by chance. Additional functional studies or gathering matched patients using Gene Matcher are needed.","PeriodicalId":16695,"journal":{"name":"Journal of pediatric genetics","volume":"11 4","pages":"287-291"},"PeriodicalIF":0.4,"publicationDate":"2021-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9578779/pdf/10-1055-s-0041-1726282.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40562275","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
