The c.859T>C (p.S287P) alteration is located in exon 1 (coding exon 1) of the CDK12 gene. This alteration results from a T to C substitution at nucleotide position 859, causing the serine (S) at amino acid position 287 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
