Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 15, 2024The c.347A>G (p.H116R) 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 347, causing the histidine (H) at amino acid position 116 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
