CDA cytidine deaminase
ENSG00000158825 · protein coding · Open Targets profile
This enzyme scavenges exogenous and endogenous cytidine and 2'-deoxycytidine for UMP synthesis. {ECO:0000269|PubMed:7923172, ECO:0000269|PubMed:9596658}.
Each row is a cancer, strongest overall evidence first. The two dots show how strong the inherited (germline) and tumour-mutation (somatic) evidence is; the line between them is the gap.
Scores run from 0 (no evidence) to 1 (strongest). A missing dot at 0 means Open Targets holds no evidence of that kind. Source: Open Targets Platform, fetched live.

gnomAD loss of function constraint: o/e 0.46542999148368835 (upper bound 0.8742200136184692). Low values mean loss of function is poorly tolerated, a safety flag for inhibition.

Registry trials of cedazuridine updated in the last three years, counted by the country group of their listed sites. A trial with sites in several groups counts in each; 56 of 74 have all sites in one country.
Site counts are not patients per country, and trials registered only outside ClinicalTrials.gov are not covered. Where sites are is a fact about the record, not a judgement of its quality. Europe is the EU and EEA, the UK and Switzerland. 4 trials list no sites and are left out. Source: ClinicalTrials.gov, fetched live.
