The c.424C>G (p.R142G) alteration is located in exon 6 (coding exon 6) of the CDC123 gene. This alteration results from a C to G substitution at nucleotide position 424, causing the arginine (R) at amino acid position 142 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
