The c.861G>C (p.W287C) alteration is located in exon 8 (coding exon 7) of the PRRC2C gene. This alteration results from a G to C substitution at nucleotide position 861, causing the tryptophan (W) at amino acid position 287 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
