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]
CCDC85C (HGNC:35459): (coiled-coil domain containing 85C) Predicted to be involved in cerebral cortex development. Located in adherens junction. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -5 ACMG points.

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.
BP4
Computational evidence support a benign effect (MetaRNN=0.117574334).
BS2
High AC in GnomAd4 at 11 Unknown,AD gene.
