Lessel et al. reported a novel neurodevelopmental disorder with severe motor impairment and absent language (NEDMIAL) in 12 individuals and identified six different de novo heterozygous missense variants in DHX30. The other clinical features included muscular hypotonia, feeding difficulties, brain anomalies, autistic features, sleep disturbances, and joint hypermobility. We report a Japanese adult with a novel missense variant and two girls with de novo missense variants in DHX30.

Background: Neurofibromatosis type 1 (NF1) is one of the most common genodermatoses. It can affect every organ and is associated with an increased risk of benign and malignant tumors. Most common tumoral locations involve nervous system and soft tissues but a large variety of tumors have been described.

Anderson-Fabry (or Fabry) disease is a rare lysosomal storage disorder caused by a functional deficiency of the enzyme alpha-galactosidase A. The partial or total defect of this lysosomal enzyme, which is caused by variants in the gene, leads to the accumulation of glycosphingolipids, mainly globotriaosylceramide in the lysosomes of different cell types. The clinical presentation of Fabry disease is multisystemic and can vary depending on the specific genetic variants associated with the disease.

Background/objectives: The failure of physiological left-right (LR) patterning, a critical embryological process responsible for establishing the asymmetric positioning of internal organs, leads to a spectrum of congenital abnormalities characterized by laterality defects, collectively known as "heterotaxy". biallelic variants have recently been associated with heterotaxy syndrome and congenital heart defects (CHD). However, the genotype-phenotype correlations and the underlying pathogenic mechanisms remain poorly understood.

Neurofibromatosis type 1 (NF1) is a complex neurocutaneous disorder caused by pathogenic variants in the gene. Although genotype-phenotype correlation studies are increasing, robust clinically relevant correlations have remained limited. We conducted a retrospective analysis of data obtained from a cohort of 204 Hungarian individuals, with a mean age of 16 years (age range: 1-33 years).

Perivascular epithelioid cell tumors (PEComas) belong to a family of rare mesenchymal tumors composed of histologically and immunohistochemically distinctive perivascular epithelioid cells. Li-Fraumeni syndrome (LFS), an autosomal dominant cancer predisposition syndrome, is caused by a germline variant of the tumor suppressor gene TP53. Here, we report the case of a 20-year-old woman with LFS who developed a PEComa of the liver.
