Collection Method: clinical testing

The c.974C>G (p.S325W) alteration is located in exon 2 (coding exon 1) of the C2CD4B gene. This alteration results from a C to G substitution at nucleotide position 974, causing the serine (S) at amino acid position 325 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
