KIF5C (kinesin family member 5C) is a kinesin heavy chain subunit involved with protein trafficing within the central nervous system and has been linked to intellectual disability.27 Little is known of the function of ZNF583 (Zinc Finger 583) beyond its description as a zinc finger protein,28 making it presumably involved in transcriptional regulation. The gene discussed is ZNF583; the disease is Intellectual disability.
