Ambry Genetics

Feb 17, 2022

The c.880G>A (p.E294K) alteration is located in exon 8 (coding exon 6) of the FAM234A gene. This alteration results from a G to A substitution at nucleotide position 880, causing the glutamic acid (E) at amino acid position 294 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
