Ambry Genetics

Oct 18, 2021

The c.133G>A (p.G45R) alteration is located in exon 4 (coding exon 2) of the FAM118A gene. This alteration results from a G to A substitution at nucleotide position 133, causing the glycine (G) at amino acid position 45 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
