Ambry Genetics

Mar 20, 2024

The c.340G>C (p.G114R) alteration is located in exon 3 (coding exon 3) of the KRT222 gene. This alteration results from a G to C substitution at nucleotide position 340, causing the glycine (G) at amino acid position 114 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
