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.3095A>T (p.D1032V) alteration is located in exon 18 (coding exon 18) of the CLSPN gene. This alteration results from a A to T substitution at nucleotide position 3095, causing the aspartic acid (D) at amino acid position 1032 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
