Uncertain significance, criteria provided, single submitter	clinical testing	Ambry Genetics	Nov 17, 2024	The p.Y1468H variant (also known as c.4402T>C), located in coding exon 14 of the CDK12 gene, results from a T to C substitution at nucleotide position 4402. The tyrosine at codon 1468 is replaced by histidine, 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. -
