BackgroundFamilial lecithin-cholesterol acyltransferase (LCAT) deficiency and α0-thalassemia are rare autosomal recessive disorders. Although both disease-causing genes reside on chromosome 16, their physical distance typically results in independent i…

ObjectiveTo perform a genetic analysis of a rare complex chimeric fetus with a 45,X/46,X,dic r(Y; Y)/46,X,r(Y) karyotype, indicated by NIPT as having sex chromosome abnormalities but with normal ultrasound findings. This study underscores the critical …

Odonto-onycho-dermal dysplasia (OODD) is a rare, autosomal recessive disorder caused by pathogenic variants in the WNT10A gene, which plays a crucial role in ectodermal tissue development, including teeth, hair, nails, and skin. We describe an 18-year-…

BackgroundDiseases associated with the germline PIGA gene include multiple congenital anomalies-hypotonia-seizures syndrome 2 (MCAHS2) and neurodevelopmental disorder with epilepsy. The clinical heterogeneity of PIGA-related diseases is extensive, so i…

ObjectiveTo identify the genetic etiology in a neonate with persistent hypertyrosinemia and characterize the functional impact of a novel TAT gene variant, c.843_844inv.MethodsA neonate suspected of having tyrosinemia type II following newborn screenin…

ObjectivesPreimplantation embryonic lethality (PREMBL) is a major cause of female infertility, characterized by early embryonic arrest. Homozygous or compound heterozygous mutations in PADI6 underlie preimplantation embryonic lethality-2 (PREMBL2). Thi…

Whole-exome sequencing of the proband and the family revealed multi-locus pathogenic variants (MGVs) leading to multiple genetic diagnoses (MGDs), explaining the complex phenotype with neuromuscular, ocular, and craniofacial abnormalities. The proband …

IntroductionGastric adenocarcinoma and proximal polyposis of the stomach (GAPPS) is a rare autosomal dominant familial gastric cancer syndrome. GAPPS is caused by pathogenic variant in the regulatory region of APC. This study describes the first Korean…

BackgroundHeterozygous variants in the ZEB2 gene are known to cause Mowat–Wilson syndrome (MWS). The classical clinical spectrum of MWS includes characteristic facial features, intellectual disability, epilepsy, Hirschsprung disease (HSCR), and various…

BackgroundPOLR3A gene-related syndrome is a complex genetic disorder with diverse clinical manifestations. Understanding its characteristics is crucial for diagnosis and management. Previous studies have reported various aspects of this syndrome, yet a…
