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 GeneticsJan 29, 2024The c.1259G>A (p.R420H) alteration is located in exon 12 (coding exon 11) of the CSNK1G1 gene. This alteration results from a G to A substitution at nucleotide position 1259, causing the arginine (R) at amino acid position 420 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
