Genes affected

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]

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

  Inheritance: AD, Unknown Classification: LIMITED Submitted by: Ambry Genetics, G2P, Labcorp Genetics (formerly Invitae)

ACMG classification
