Genes affected

CHEK1 (HGNC:1925): (checkpoint kinase 1) The protein encoded by this gene belongs to the Ser/Thr protein kinase family. It is required for checkpoint mediated cell cycle arrest in response to DNA damage or the presence of unreplicated DNA. This protein acts to integrate signals from ATM and ATR, two cell cycle proteins involved in DNA damage responses, that also associate with chromatin in meiotic prophase I. Phosphorylation of CDC25A protein phosphatase by this protein is required for cells to delay cell cycle progression in response to double-strand DNA breaks. Several alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Oct 2011]

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.230G>T (p.G77V) alteration is located in exon 3 (coding exon 2) of the CHEK1 gene. This alteration results from a G to T substitution at nucleotide position 230, causing the glycine (G) at amino acid position 77 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

PreventionGenetics, part of Exact Sciences

Significance: Uncertain significance

Review Status: no assertion criteria provided

Collection Method: clinical testing

The CHEK1 c.230G>T variant is predicted to result in the amino acid substitution p.Gly77Val. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.28% of alleles in individuals of Latino descent in gnomAD and is not reported in ClinVar. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
