The c.860G>A (p.C287Y) alteration is located in exon 7 (coding exon 5) of the RNMT gene. This alteration results from a G to A substitution at nucleotide position 860, causing the cysteine (C) at amino acid position 287 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
