Collection Method: clinical testing

The c.194A>G (p.N65S) alteration is located in exon 1 (coding exon 1) of the RFPL3 gene. This alteration results from a A to G substitution at nucleotide position 194, causing the asparagine (N) at amino acid position 65 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
