Collection Method: clinical testing

The c.427C>G (p.L143V) alteration is located in exon 2 (coding exon 1) of the ATP6V1E2 gene. This alteration results from a C to G substitution at nucleotide position 427, causing the leucine (L) at amino acid position 143 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
