Genes affected

ATP6V0B (HGNC:861): (ATPase H+ transporting V0 subunit b) This gene encodes a portion of the V0 domain of vacuolar ATPase (V-ATPase), a multisubunit enzyme that mediates acidification of eukaryotic intracellular organelles. Activity of this enzyme is necessary for such varied processes as protein sorting, zymogen activation, receptor-mediated endocytosis, and synaptic vesicle proton gradient generation. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jun 2014]

Collection Method: clinical testing

The c.125C>T (p.T42M) alteration is located in exon 3 (coding exon 3) of the ATP6V0B gene. This alteration results from a C to T substitution at nucleotide position 125, causing the threonine (T) at amino acid position 42 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
