The c.4223A>G (p.N1408S) alteration is located in exon 22 (coding exon 21) of the RAD54L2 gene. This alteration results from a A to G substitution at nucleotide position 4223, causing the asparagine (N) at amino acid position 1408 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
