Genes affected

ATP6V1H (HGNC:18303): (ATPase H+ transporting V1 subunit H) This gene encodes a component of vacuolar ATPase (V-ATPase), a multisubunit enzyme that mediates acidification of intracellular organelles. V-ATPase-dependent organelle acidification is necessary for multiple processes including protein sorting, zymogen activation, receptor-mediated endocytosis, and synaptic vesicle proton gradient generation. The encoded protein is the regulatory H subunit of the V1 domain of V-ATPase, which is required for catalysis of ATP but not the assembly of V-ATPase. Decreased expression of this gene may play a role in the development of type 2 diabetes. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.

The c.665A>G (p.D222G) alteration is located in exon 8 (coding exon 7) of the ATP6V1H gene. This alteration results from a A to G substitution at nucleotide position 665, causing the aspartic acid (D) at amino acid position 222 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
