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.1552G>A (p.D518N) alteration is located in exon 10 (coding exon 10) of the CDT1 gene. This alteration results from a G to A substitution at nucleotide position 1552, causing the aspartic acid (D) at amino acid position 518 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with CDT1-related conditions. ClinVar contains an entry for this variant (Variation ID: 434679). This variant is present in population databases (rs751315293, ExAC 0.06%). This sequence change replaces aspartic acid with asparagine at codon 518 of the CDT1 protein (p.Asp518Asn). The aspartic acid residue is moderately conserved and there is a small physicochemical difference between aspartic acid and asparagine. -
