Genes affected

CDT1 (HGNC:24576): (chromatin licensing and DNA replication factor 1) The protein encoded by this gene is involved in the formation of the pre-replication complex that is necessary for DNA replication. The encoded protein can bind geminin, which prevents replication and may function to prevent this protein from initiating replication at inappropriate origins. Phosphorylation of this protein by cyclin A-dependent kinases results in degradation of the protein. [provided by RefSeq, Mar 2011]

The c.32C>T (p.A11V) alteration is located in exon 1 (coding exon 1) of the CDT1 gene. This alteration results from a C to T substitution at nucleotide position 32, causing the alanine (A) at amino acid position 11 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
