Ambry Genetics

Apr 25, 2022

The c.3277G>A (p.A1093T) alteration is located in exon 18 (coding exon 18) of the HELQ gene. This alteration results from a G to A substitution at nucleotide position 3277, causing the alanine (A) at amino acid position 1093 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
