Ambry Genetics

Dec 22, 2023

The c.625G>A (p.V209M) alteration is located in exon 6 (coding exon 5) of the CFAP99 gene. This alteration results from a G to A substitution at nucleotide position 625, causing the valine (V) at amino acid position 209 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
