Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 3P and 2B. PM2 PP5 BP4 BP7

The NM_005765.3(ATP6AP2):c.345C>T(p.Ser115=) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Pathogenic (no stars).

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 Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant X-40597293-C-T is Pathogenic according to our data. Variant chrX-40597293-C-T is described in ClinVar as [Pathogenic]. Clinvar id is 88756.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chrX-40597293-C-T is described in Lovd as [Pathogenic].
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.32).. Strength limited to SUPPORTING due to the PP5.
• BP7: Synonymous conserved (PhyloP=0.261 with no splicing effect.
