Ambry Genetics

Feb 23, 2023

The c.2656G>A (p.A886T) alteration is located in exon 22 (coding exon 21) of the SLC9C2 gene. This alteration results from a G to A substitution at nucleotide position 2656, causing the alanine (A) at amino acid position 886 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
