The c.422A>C (p.Y141S) alteration is located in exon 2 (coding exon 2) of the SRD5A1 gene. This alteration results from a A to C substitution at nucleotide position 422, causing the tyrosine (Y) at amino acid position 141 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
