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]

Submissions by phenotype

not provided Uncertain:2
Uncertain significance, criteria provided, single submitterclinical testingInvitaeJan 24, 2024This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 344 of the CDT1 protein (p.Glu344Lys). This variant is present in population databases (rs587780303, gnomAD 0.003%). This missense change has been observed in individual(s) with growth abnormality (PMID: 26633542). ClinVar contains an entry for this variant (Variation ID: 128659). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. 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. -
