Ambry Genetics

Nov 13, 2023

The c.469G>A (p.V157I) alteration is located in exon 6 (coding exon 6) of the FAM131B gene. This alteration results from a G to A substitution at nucleotide position 469, causing the valine (V) at amino acid position 157 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
