We collected these data on CSNK2A1 and CSNK2B variants with the aim to provide a consolidated resource on CSNK2A1 and CSNK2B variants, and analyzed all the mutants using diverse methods to provide integrated information on their potential functional effects that can be used to inform researchers of OCNDS and POBINDS syndromes. This evidence concerns the gene CSNK2A1 and Okur-Chung neurodevelopmental syndrome.
