Kury et al., 2017 reported 10 individuals with intellectual disability that were found to carry de novo variants in the CAMK2B gene, many of which were experimentally shown to have either loss-of-function or gain-of-function effects; three of these individuals also presented with ASD/autistic features.
Molecular Function
The product of this gene belongs to the serine/threonine protein kinase family and to the Ca(2+)/calmodulin-dependent protein kinase subfamily. Calcium signaling is crucial for several aspects of plasticity at glutamatergic synapses. In mammalian cells, the enzyme is composed of four different chains: alpha, beta, gamma, and delta. The product of this gene is a beta chain.

Syndromic
Kury et al., 2017 reported 10 individuals with intellectual disability that were found to carry de novo variants in the CAMK2B gene, many of which were experimentally shown to have either loss-of-function or gain-of-function effects; three of these individuals also presented with ASD/autistic features.
Score Delta: Score remained at S
criteria met
See SFARI Gene'scoring criteriaThe syndromic category includes mutations that are associated with a substantial degree of increased risk and consistently linked to additional characteristics not required for an ASD diagnosis. If there is independent evidence implicating a gene in idiopathic ASD, it will be listed as "#S" (e.g., 2S, 3S, etc.). If there is no such independent evidence, the gene will be listed simply as "S."
