Genes affected
CSNK1G1 (HGNC:2454): (casein kinase 1 gamma 1) This gene encodes a member of the casein kinase I gene family. This family is comprised of serine/threonine kinases that phosphorylate acidic proteins such as caseins. The encoded kinase plays a role in cell cycle checkpoint arrest in response to stalled replication forks by phosphorylating Claspin. A mutation in this gene may be associated with non-syndromic early-onset epilepsy (NSEOE). [provided by RefSeq, Jul 2016]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 07, 2024The c.767C>G (p.A256G) alteration is located in exon 8 (coding exon 7) of the CSNK1G1 gene. This alteration results from a C to G substitution at nucleotide position 767, causing the alanine (A) at amino acid position 256 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
