Ambry Genetics

Oct 01, 2024

The c.791G>A (p.R264H) alteration is located in exon 5 (coding exon 4) of the RFPL2 gene. This alteration results from a G to A substitution at nucleotide position 791, causing the arginine (R) at amino acid position 264 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
