The c.572A>C (p.K191T) alteration is located in exon 2 (coding exon 1) of the ATP6V1E2 gene. This alteration results from a A to C substitution at nucleotide position 572, causing the lysine (K) at amino acid position 191 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
