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:):

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.30678964).

The c.914A>G (p.D305G) alteration is located in exon 8 (coding exon 7) of the CSNK1E gene. This alteration results from a A to G substitution at nucleotide position 914, causing the aspartic acid (D) at amino acid position 305 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
