Genes affected

CAMK2D (HGNC:1462): (calcium/calmodulin dependent protein kinase II delta) 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 delta chain. Alternative splicing results in multiple transcript variants encoding distinct isoforms. Distinct isoforms of this chain have different expression patterns.[provided by RefSeq, Nov 2008]

The c.749A>G (p.N250S) alteration is located in exon 10 (coding exon 10) of the CAMK2D gene. This alteration results from a A to G substitution at nucleotide position 749, causing the asparagine (N) at amino acid position 250 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
