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]

The c.872G>A (p.R291Q) alteration is located in exon 9 (coding exon 8) of the CSNK1G1 gene. This alteration results from a G to A substitution at nucleotide position 872, causing the arginine (R) at amino acid position 291 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
