The c.409C>T (p.R137W) alteration is located in exon 2 (coding exon 1) of the ZC2HC1C gene. This alteration results from a C to T substitution at nucleotide position 409, causing the arginine (R) at amino acid position 137 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
