Variant summary

Our verdict is Uncertain significance. The variant received 4 ACMG points: 4P and 0B. PM2 PP3_Moderate

The NM_152221.3(CSNK1E):​c.286T>A​(p.Cys96Ser) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. C96F) has been classified as Uncertain significance.

Genes affected

CSNK1E (HGNC:2453): (casein kinase 1 epsilon) The protein encoded by this gene is a serine/threonine protein kinase and a member of the casein kinase I protein family, whose members have been implicated in the control of cytoplasmic and nuclear processes, including DNA replication and repair. The encoded protein is found in the cytoplasm as a monomer and can phosphorylate a variety of proteins, including itself. This protein has been shown to phosphorylate period, a circadian rhythm protein. Two transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, Feb 2014]

TPTEP2-CSNK1E (HGNC:53829): (TPTEP2-CSNK1E readthrough) This locus represents naturally occurring readthrough transcription between the neighboring LOC400927 (transmembrane phosphoinositide 3-phosphatase and tensin homolog 2 pseudogene) and CSNK1E (casein kinase I isoform epsilon) genes on chromosome 22. The readthrough transcript encodes the same protein as the downstream gene product (casein kinase I isoform epsilon). [provided by RefSeq, Feb 2014]

ACMG classification

Our verdict: Uncertain_significance. The variant received 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.873
