Case Report: Novel pathogenic variant in autosomal recessive WNT10A-related odonto-onycho-dermal dysplasia
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-…

Case Report: Biallelic PADI6 frameshift variants contribute to preimplantation embryonic lethality
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…

Co-occurring DMD, GJA1, and novel FYCO1 variants in a proband from a consanguineous oculodentodigital dysplasia family: a rare multi-locus case report
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 …

Case Report: Identification of a de novo missense variant in the N-terminal zinc-finger domain of ZEB2 in a patient presenting with neurodevelopmental delay and recurrent pulmonary infections
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…
