The c.722A>C (p.K241T) alteration is located in exon 2 (coding exon 2) of the RFPL1 gene. This alteration results from a A to C substitution at nucleotide position 722, causing the lysine (K) at amino acid position 241 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
