Genes affected
ATP6V0A2 (HGNC:18481): (ATPase H+ transporting V0 subunit a2) The protein encoded by this gene is a subunit of the vacuolar ATPase (v-ATPase), an heteromultimeric enzyme that is present in intracellular vesicles and in the plasma membrane of specialized cells, and which is essential for the acidification of diverse cellular components. V-ATPase is comprised of a membrane peripheral V(1) domain for ATP hydrolysis, and an integral membrane V(0) domain for proton translocation. The subunit encoded by this gene is a component of the V(0) domain. Mutations in this gene are a cause of both cutis laxa type II and wrinkly skin syndrome. [provided by RefSeq, Jul 2009]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -13 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.013159156).
BP6
Variant 12-123744756-G-A is Benign according to our data. Variant chr12-123744756-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 166708.
BS1
Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.000512 (78/152254) while in subpopulation SAS AF = 0.00622 (30/4820). AF 95% confidence interval is 0.00448. There are 0 homozygotes in GnomAd4. There are 51 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
BS2
High Homozygotes in GnomAdExome4 at 13 AR gene
