Ambry Genetics

Apr 22, 2022

The c.91G>T (p.G31C) alteration is located in exon 1 (coding exon 1) of the SRXN1 gene. This alteration results from a G to T substitution at nucleotide position 91, causing the glycine (G) at amino acid position 31 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
