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

ACMG classification

Our verdict: Uncertain_significance. The variant received 5 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 7 curated pathogenic missense variants (we use a threshold of 10). The gene has 1 curated benign missense variants. Gene score misZ: 3.1055 (above the threshold of 3.09). Trascript score misZ: 1.1706 (below the threshold of 3.09). GenCC associations: The gene is linked to complex neurodevelopmental disorder, CAMK2D-related neurodevelopmental disorder and dilated cardiomyopathy.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.901

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.1195T>C (p.F399L) alteration is located in exon 16 (coding exon 16) of the CAMK2D gene. This alteration results from a T to C substitution at nucleotide position 1195, causing the phenylalanine (F) at amino acid position 399 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
