Feb 28, 2024

The c.838C>A (p.H280N) alteration is located in exon 2 (coding exon 2) of the RFPL1 gene. This alteration results from a C to A substitution at nucleotide position 838, causing the histidine (H) at amino acid position 280 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
