The p.G1461C variant (also known as c.4381G>T), located in coding exon 14 of the CDK12 gene, results from a G to T substitution at nucleotide position 4381. The glycine at codon 1461 is replaced by cysteine, an amino acid with highly dissimilar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Based on the available evidence, the clinical significance of this variant remains unclear.
