Genes affected
CAMK2A (HGNC:1460): (calcium/calmodulin dependent protein kinase II alpha) The product of this gene belongs to the serine/threonine protein kinases family, and to the Ca(2+)/calmodulin-dependent protein kinases subfamily. Calcium signaling is crucial for several aspects of plasticity at glutamatergic synapses. This calcium calmodulin-dependent protein kinase is composed of four different chains: alpha, beta, gamma, and delta. The alpha chain encoded by this gene is required for hippocampal long-term potentiation (LTP) and spatial learning. In addition to its calcium-calmodulin (CaM)-dependent activity, this protein can undergo autophosphorylation, resulting in CaM-independent activity. Several transcript variants encoding distinct isoforms have been identified for this gene. [provided by RefSeq, Jun 2018]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -2 ACMG points.

PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), CAMK2A. . Gene score misZ 4.6751 (greater than the threshold 3.09). Trascript score misZ 6.103 (greater than threshold 3.09). GenCC has associacion of gene with intellectual disability, autosomal recessive 63, intellectual disability, autosomal dominant 40, autosomal dominant non-syndromic intellectual disability, intellectual disability, autosomal dominant 53.
BP4
Computational evidence support a benign effect (MetaRNN=0.10913101).
BS1
Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.0000657 (10/152254) while in subpopulation AFR AF= 0.000217 (9/41470). AF 95% confidence interval is 0.000113. There are 0 homozygotes in gnomad4. There are 4 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
