Genes affected

CCNK (HGNC:1596): (cyclin K) The protein encoded by this gene is a member of the transcription cyclin family. These cyclins may regulate transcription through their association with and activation of cyclin-dependent kinases (CDK) that phosphorylate the C-terminal domain (CTD) of the large subunit of RNA polymerase II. This gene product may play a dual role in regulating CDK and RNA polymerase II activities. [provided by RefSeq, Jul 2008]

CCNK Gene-Disease associations (from GenCC):

intellectual developmental disorder with hypertelorism and distinctive facies

ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 4 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 1 curated pathogenic missense variants (we use a threshold of 10). The gene has 0 curated benign missense variants. Gene score misZ: 3.305 (above the threshold of 3.09). Trascript score misZ: 1.9964 (below the threshold of 3.09). GenCC associations: The gene is linked to intellectual developmental disorder with hypertelorism and distinctive facies.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.775
