Genes affected
CSNK2A1 (HGNC:2457): (casein kinase 2 alpha 1) Casein kinase II is a serine/threonine protein kinase that phosphorylates acidic proteins such as casein. It is involved in various cellular processes, including cell cycle control, apoptosis, and circadian rhythm. The kinase exists as a tetramer and is composed of an alpha, an alpha-prime, and two beta subunits. The alpha subunits contain the catalytic activity while the beta subunits undergo autophosphorylation. The protein encoded by this gene represents the alpha subunit. Multiple transcript variants encoding different protein isoforms have been found for this gene. [provided by RefSeq, Apr 2018]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -1 ACMG points.

PP2
Missense variant in the CSNK2A1 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 28 curated pathogenic missense variants (we use a threshold of 10). The gene has 7 curated benign missense variants. Gene score misZ: 3.7123 (above the threshold of 3.09). Trascript score misZ: 5.3205 (above the threshold of 3.09). GenCC associations: The gene is linked to Okur-Chung neurodevelopmental syndrome, syndromic intellectual disability.
BP4
Computational evidence support a benign effect (MetaRNN=0.21049312).
