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]

CAMK2D Gene-Disease associations (from GenCC):

• CAMK2D-related neurodevelopmental disorder and dilated cardiomyopathy

  Inheritance: AD Classification: MODERATE Submitted by: G2P
• complex neurodevelopmental disorder

  Inheritance: AD Classification: MODERATE Submitted by: Ambry Genetics

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.75).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.42 is higher than 0.05.
