Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.120G>A (p.M40I) alteration is located in exon 2 (coding exon 1) of the RRAD gene. This alteration results from a G to A substitution at nucleotide position 120, causing the methionine (M) at amino acid position 40 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
