The c.1217T>G (p.M406R) alteration is located in exon 9 (coding exon 8) of the RAD54L2 gene. This alteration results from a T to G substitution at nucleotide position 1217, causing the methionine (M) at amino acid position 406 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
