The c.349A>G (p.R117G) alteration is located in exon 1 (coding exon 1) of the CDK12 gene. This alteration results from a A to G substitution at nucleotide position 349, causing the arginine (R) at amino acid position 117 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
