Collection Method: clinical testing

The c.694A>G (p.M232V) alteration is located in exon 7 (coding exon 7) of the USP30 gene. This alteration results from a A to G substitution at nucleotide position 694, causing the methionine (M) at amino acid position 232 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
