Collection Method: clinical testing

The c.19G>A (p.V7M) alteration is located in exon 1 (coding exon 1) of the SRD5A1 gene. This alteration results from a G to A substitution at nucleotide position 19, causing the valine (V) at amino acid position 7 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
