The c.1523A>G (p.Y508C) alteration is located in exon 15 (coding exon 15) of the OVCH2 gene. This alteration results from a A to G substitution at nucleotide position 1523, causing the tyrosine (Y) at amino acid position 508 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
