Genes affected

CLSPN (HGNC:19715): (claspin) The product of this gene is an essential upstream regulator of checkpoint kinase 1 and triggers a checkpoint arrest of the cell cycle in response to replicative stress or DNA damage. The protein is also required for efficient DNA replication during a normal S phase. Multiple transcript variants encoding different isoforms have been found for this gene.

The c.3445A>G (p.M1149V) alteration is located in exon 21 (coding exon 21) of the CLSPN gene. This alteration results from a A to G substitution at nucleotide position 3445, causing the methionine (M) at amino acid position 1149 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
