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

Verdict is Benign. Variant got -8 ACMG points.

• BS1: Variant frequency is greater than expected in population amr. gnomad4_exome allele frequency = 0.00042 (26/61838) while in subpopulation AMR AF= 0.00141 (2/1420). AF 95% confidence interval is 0.000343. There are 0 homozygotes in gnomad4_exome. There are 16 alleles in male gnomad4_exome subpopulation. This position pass quality control queck.
• BS2: High AC in GnomAdExome4 at 26 AD gene.
