Collection Method: clinical testing

The c.2794G>A (p.E932K) alteration is located in exon 1 (coding exon 1) of the RAD51AP2 gene. This alteration results from a G to A substitution at nucleotide position 2794, causing the glutamic acid (E) at amino acid position 932 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
