Ambry Genetics

Nov 04, 2022

The c.655G>A (p.A219T) alteration is located in exon 4 (coding exon 4) of the SRD5A1 gene. This alteration results from a G to A substitution at nucleotide position 655, causing the alanine (A) at amino acid position 219 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
