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]

This sequence change replaces valine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 164 of the ATP6AP2 protein (p.Val164Ile). This variant is present in population databases (rs142013283, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with ATP6AP2-related conditions. ClinVar contains an entry for this variant (Variation ID: 204912). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt ATP6AP2 protein function with a negative predictive value of 80%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

ATP6AP2 NM_005765 exon 5 p.Val164Ile (c.490G>A): This variant has not been reported in the literature but is present in 3/27186 Latino alleles, including 1 hemizygote in the Genome Aggregation Database (http://gnomad.broadinstitute.org/rs142013283). This variant is present in ClinVar (Variation ID:204912). This variant amino acid Isoleucine (Ile) is present in >30 species and is not well conserved among evolutionarily distant species; this suggests that this variant may not impact the protein. Additional computational prediction tools do not suggest an impact. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain. -

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
