Genes affected

CAMK2G (HGNC:1463): (calcium/calmodulin dependent protein kinase II gamma) The product of this gene is one of the four subunits of an enzyme which 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 gamma chain. Many alternatively spliced transcripts encoding different isoforms have been described but the full-length nature of all the variants has not been determined.[provided by RefSeq, Mar 2011]

The missense c.1256C>Tp.Pro419Leu variant in CAMK2G gene has not been reported previously as a pathogenic variant nor a benign variant, to our knowledge. The p.Pro419Leu variant is novel not in any individuals in gnomAD Exomes and 1000 Genomes. This variant has not been reported to the ClinVar database. The amino acid change p.Pro419Leu in CAMK2G is predicted as conserved by GERP++ and PhyloP across 100 vertebrates. The amino acid Pro at position 419 is changed to a Leu changing protein sequence and it might alter its composition and physico-chemical properties. For these reasons, this variant has been classified as a Variant of Uncertain Significance VUS. -
