Ambry Genetics

May 14, 2024

The c.187A>G (p.K63E) alteration is located in exon 3 (coding exon 2) of the FARP2 gene. This alteration results from a A to G substitution at nucleotide position 187, causing the lysine (K) at amino acid position 63 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
