Genes affected

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]

TP53I13 (HGNC:25102): (tumor protein p53 inducible protein 13) Involved in several processes, including negative regulation of cell cycle; response to UV; and response to xenobiotic stimulus. Located in cytoplasm. [provided by Alliance of Genome Resources, Apr 2022]

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

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.100819975).
