Genes affected

ATP6AP2 (HGNC:18305): (ATPase H+ transporting accessory protein 2) This gene encodes a protein that is associated with adenosine triphosphatases (ATPases). Proton-translocating ATPases have fundamental roles in energy conservation, secondary active transport, acidification of intracellular compartments, and cellular pH homeostasis. There are three classes of ATPases- F, P, and V. The vacuolar (V-type) ATPases have a transmembrane proton-conducting sector and an extramembrane catalytic sector. The encoded protein has been found associated with the transmembrane sector of the V-type ATPases. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Likely_benign. Variant got -4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.57).
• BP6: Variant X-40581030-C-T is Benign according to our data. Variant chrX-40581030-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 382919.Status of the report is criteria_provided_single_submitter, 1 stars.
