What premarital genetic screening programs exist in countries with high consanguineous-marriage rates?

Direct answer
Countries including Cyprus, Iran and several Gulf states have used carrier screening, counseling, public education and prenatal diagnosis to reduce severe haemoglobin disorders. Programs differ: some are voluntary, some require a certificate before marriage, and some target schools, families or high-risk regions. A certificate does not necessarily prohibit marriage; it may document that counseling occurred. International evidence shows that screening works best with accurate laboratory testing, confidentiality, informed choice and accessible follow-up, rather than stigma or assuming every related couple carries the same risk.
