Ambry Genetics

Feb 22, 2023

The c.394G>A (p.V132I) alteration is located in exon 3 (coding exon 3) of the CFAP77 gene. This alteration results from a G to A substitution at nucleotide position 394, causing the valine (V) at amino acid position 132 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
