Ambry Genetics

Mar 02, 2023

The c.544G>A (p.G182R) alteration is located in exon 6 (coding exon 6) of the SAMM50 gene. This alteration results from a G to A substitution at nucleotide position 544, causing the glycine (G) at amino acid position 182 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
