Ambry Genetics

May 07, 2024

The c.256G>A (p.V86M) alteration is located in exon 3 (coding exon 1) of the FAM114A1 gene. This alteration results from a G to A substitution at nucleotide position 256, causing the valine (V) at amino acid position 86 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
