High Prevalence of Congenital Hypothyroidism in the Greek Cypriot Population: Results of the Neonatal Screening Program 1990- 2000

The incidence of primary CH in Greek Cypriots is 1/1800 live births. The most common etiology is thyroid dysgenesis. Initial T4 levels correlated with the degree of skeletal maturation and the etiology. Initial TSH level, although lower in children with transient CH, could not predict the nature of CH.
