Ambry Genetics

Dec 26, 2023

The c.601G>A (p.V201M) alteration is located in exon 3 (coding exon 3) of the XKR8 gene. This alteration results from a G to A substitution at nucleotide position 601, causing the valine (V) at amino acid position 201 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
