Ambry Genetics

Dec 28, 2023

The c.105G>A (p.M35I) alteration is located in exon 2 (coding exon 2) of the RNF181 gene. This alteration results from a G to A substitution at nucleotide position 105, causing the methionine (M) at amino acid position 35 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
