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 made for transcript

Verdict is Pathogenic. Variant got 12 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
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 syndromic intellectual disability, Okur-Chung neurodevelopmental syndrome.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.796
PP5
Variant 20-505191-C-T is Pathogenic according to our data. Variant chr20-505191-C-T is described in ClinVar as [Likely_pathogenic]. Clinvar id is 224796.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

Significance: Pathogenic
Review Status: criteria provided, single submitter
Collection Method: clinical testing

Same nucleotide change resulting in same amino acid change has been previously reported as de novoo and observed in at least two similarly affected unrelated individuals (ClinVar ID: VCV000224796.3, PMID:28135719, 29240241, 27048600, and 29383814, PS2 and PS4). The missense variant is located in a mutational hot spot and/or well-established functional domain in which established pathogenic variants have been reported (PM1). It is not observed in the gnomAD v2.1.1 dataset (PM2). A different missense change at the same codon (p.Arg47Gly) has been reported as pathogenic/likely pathogenic with strong evidence (ClinVar ID: VCV000280816.3, PM5). The variant was observed as assumed (i.e. paternity and maternity not confirmed) de novoo (3billion dataset, PM6). Therefore, this variant is classified as pathogenic according to the recommendation of ACMG/AMP guideline. -

Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as Pathogenic. Following criteria are met: 0102 - Loss of function is a known mechanism of disease in this gene and is associated with Okur-Chung neurodevelopmental syndrome (MIM#617062). The mechanism of missense variants is unclear. (I) 0107 - This gene is associated with autosomal dominant disease. (I) 0200 - Variant is predicted to result in a missense amino acid change from arginine to glutamine. (I) 0251 - This variant is heterozygous. (I) 0301 - Variant is absent from gnomAD (both v2 and v3). (SP) 0502 - Missense variant with conflicting in silico predictions and high conservation. (I) 0602 - Variant is located in a hotspot region or cluster of pathogenic variants (DECIPHER). (SP) 0801 - This variant has strong previous evidence of pathogenicity in unrelated individuals. This variant has been reported several times as likely pathogenic and pathogenic (ClinVar), and observed as de novo in multiple individuals with developmental delay (VCGS, DECIPHER, PMID: 27048600; PMID: 29383814). (SP) 1203 - This variant has been shown to be de novo in the proband (parental status confirmed, by trio analysis).
