Given the course of X-linked dominant inheritance, affected males can only survive in the state of mosaicism for a PORCN pathogenic variant or in the presence of XXY karyotype. FDH is a multisystemic disorder in which cutaneous, ocular, and skeletal systems are primarily affected. Patients also may display intellectual disability and central nervous system abnormalities, yet most may have normal mental development. Case Presentation: We report on a currently 11-year-old female patient with a novel missense heterozygous PORCN variant who exhibited classical ectodermal, skeletal, and ocular findings in addition to mild intellectual disability, left-side diaphragm eventration, and puberty precox, a finding yet unreported in the literature. Conclusion: With this report, we aimed to expand the mutational spectrum and give insight into the importance of neurologic and skeletal system evaluation among other clinical features of FDH. Although gastrointestinal and genitourinary problems can occur during the course of the disease, to our knowledge, left-side diaphragm eventration and puberty precox are new features that have not been reported previously.","PeriodicalId":48566,"journal":{"name":"Molecular Syndromology","volume":"11 5","pages":""},"PeriodicalIF":1.1,"publicationDate":"2024-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139385271","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The “centrosomal protein 19 (CEP19)” gene encodes for a centrosomal and ciliary protein. Homozygous variants in the CEP19 gene are extremely rare causes of early-onset severe monogenic obesity. Herein, we present a Turkish family with early-onset severe obesity with variable features. Methods: Sanger sequencing and whole-exome sequencing were performed to identify the genetic etiology in the family. Results: The index case was a 12-year-old female who presented with severe obesity (BMI of 62.7 kg/m2), metabolic syndrome, and diabetic ketoacidosis. Her nonidentical twin female siblings also had early-onset severe obesity, metabolic syndrome, and diabetes. In addition, one of the affected siblings had situs inversus abdominalis, polysplenia, lumbar vertebral fusion, and abnormal lateralization. A novel homozygous nonsense (c.169C>T, p. Arg57*) pathogenic variant was detected in exon 3 of the CEP19 gene in all affected members of the family. One unaffected sister and unaffected parents were heterozygous for the variant. This variant is predicted to cause a stop codon at amino acid sequence 57, leading to a truncated CEP19 protein. Discussion/Conclusion: Our study expands the phenotypical manifestations and variation database of CEP19 variants. The findings in one of our patients reaffirm its role in the assembly and function of both motile and immotile cilia.","PeriodicalId":48566,"journal":{"name":"Molecular Syndromology","volume":"178 11","pages":""},"PeriodicalIF":1.1,"publicationDate":"2023-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139172473","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This condition, distinctly separated from Schinzel-Giedion syndrome, is referred to as autosomal dominant mental retardation 29 (ADR29). Case Presentation: In this report, we present the case of a 6-year-old male patient exhibiting fine and global motor skill impairments along with expressive language delay. The patient carried a novel germline, heterozygous, de novo nonsense variant in the SETBP1 gene, specifically the c.532C>T variant, which prematurely terminates protein translation at amino acid 178, p.(Gln178*), and removes more than 10% of the reference protein isoform consisting of 1,596 amino acids. According to the American College of Medical Genetics and Genomics (ACMG) guidelines, this variant has been classified as pathogenic. Conclusion: Given the limited number of ADR29 cases reported to date, it is critical to focus attention on the phenotypic features of each new individual and seek out previously undocumented defects. The clinical findings found in our patient align with current knowledge on the correlation between the genotypes characterized by loss-of-function variants in SETBP1 gene and a particular neurological phenotype. Furthermore, the presence of a severely delayed bone age in this patient, which we report for the first time, could indicate a possible indirect but significant contribution of the SETBP1 protein in bone development and maturation processes. This finding highlights the need for further investigation into the potential effects of SETBP1 gene variants on bone health and the possible involvement of the SETBP1 protein in skeletal growth and development.","PeriodicalId":48566,"journal":{"name":"Molecular Syndromology","volume":"11 34","pages":""},"PeriodicalIF":1.1,"publicationDate":"2023-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138977046","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We have compared his characteristics with the genotypes and phenotypes of 34 PCDH19 mosaic males earlier reported in the literature. Finally, we have summarized today’s knowledge about phenotype-genotype correlation and pharmacological response in these patients.
