The c.191T>C (p.I64T) alteration is located in exon 2 (coding exon 1) of the ATP6V1E2 gene. This alteration results from a T to C substitution at nucleotide position 191, causing the isoleucine (I) at amino acid position 64 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
