Ambry Genetics

Aug 16, 2022

The c.2909G>C (p.G970A) alteration is located in exon 15 (coding exon 15) of the HELQ gene. This alteration results from a G to C substitution at nucleotide position 2909, causing the glycine (G) at amino acid position 970 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
