Genes affected

GAPVD1 (HGNC:23375): (GTPase activating protein and VPS9 domains 1) Enables GTPase activating protein binding activity and guanyl-nucleotide exchange factor activity. Involved in regulation of protein transport. Located in cytosol and plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Pathogenic. Variant got 10 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
