Ambry Genetics

May 18, 2022

The c.418T>A (p.S140T) alteration is located in exon 4 (coding exon 2) of the FAM114A1 gene. This alteration results from a T to A substitution at nucleotide position 418, causing the serine (S) at amino acid position 140 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
