Collection Method: clinical testing

The p.S1287A variant (also known as c.3859T>G), located in coding exon 14 of the CDK12 gene, results from a T to G substitution at nucleotide position 3859. The serine at codon 1287 is replaced by alanine, an amino acid with similar 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. -
