The Department of Clinical Genetics (DCG) provides a public genetics service to referring clinicians for patients and families in the Republic of Ireland affected by, or at risk of, a genetic disorder.  It is estimated that European populations have a 6%-8% lifetime prevalence of having a rare disease, the majority of which are genetic.  DCG provides public diagnostic services for a broad range of hereditary disorders and, because of the familial nature of genetic disorders, serves both adults and children.  The Department comprises three integrated divisions:

  • Clinical Genetics

  • Cytogenetics

  • Molecular Genetics
