Ambry Genetics

Feb 06, 2023

The c.32G>A (p.G11D) alteration is located in exon 1 (coding exon 1) of the KRTAP6-2 gene. This alteration results from a G to A substitution at nucleotide position 32, causing the glycine (G) at amino acid position 11 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
