The c.635G>T (p.R212L) alteration is located in exon 5 (coding exon 4) of the RFPL2 gene. This alteration results from a G to T substitution at nucleotide position 635, causing the arginine (R) at amino acid position 212 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
