Collection Method: clinical testing

The c.2933T>G (p.F978C) alteration is located in exon 1 (coding exon 1) of the RAD51AP2 gene. This alteration results from a T to G substitution at nucleotide position 2933, causing the phenylalanine (F) at amino acid position 978 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
