Genes affected

ANKRD13B (HGNC:26363): (ankyrin repeat domain 13B) Enables ubiquitin-dependent protein binding activity. Involved in negative regulation of receptor internalization. Located in endosome; perinuclear region of cytoplasm; and plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

ABHD15-AS1 (HGNC:49685): (ABHD15 antisense RNA 1)

GIT1 (HGNC:4272): (GIT ArfGAP 1) Enables gamma-tubulin binding activity. Involved in positive regulation of microtubule nucleation and regulation of cytokinesis. Located in several cellular components, including focal adhesion; microtubule cytoskeleton; and mitochondrion. Implicated in attention deficit hyperactivity disorder. Biomarker of Huntington's disease. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Benign. Variant got -10 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.44).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.739 is higher than 0.05.
