The c.3977A>G (p.Y1326C) 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 3977, causing the tyrosine (Y) at amino acid position 1326 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
