The c.499C>T (p.R167W) alteration is located in exon 4 (coding exon 3) of the RCN3 gene. This alteration results from a C to T substitution at nucleotide position 499, causing the arginine (R) at amino acid position 167 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
