Alpha-thalassaemia in Cyprus
Insights
Alpha-thalassaemia, a genetic blood disorder, is prevalent in Cyprus. Studies found high frequencies of alpha-thalassaemia carriers among Greek and Turkish Cypriot newborns, indicating a significant public health concern.
Area of Science:
- Genetics
- Hematology
- Public Health
Background:
- Alpha-thalassaemia is a common inherited blood disorder.
- Carrier screening is crucial for genetic counseling and disease prevention.
Purpose of the Study:
- To determine the frequency of alpha-thalassaemia carriers in Cyprus.
- To compare carrier rates between Greek Cypriot and Turkish Cypriot populations.
Main Methods:
- Newborn screening using haemoglobin Bart's analysis.
- Analysis of 1200 Greek Cypriot and 132 Turkish Cypriot newborns.
Main Results:
- 12.4% of Greek Cypriot newborns and 6.8% of Turkish Cypriot newborns showed elevated haemoglobin Bart's levels.
- Elevated levels indicate carriership of alpha-thalassaemia-1 or alpha-thalassaemia-2 genes.
Conclusions:
- Cyprus exhibits the highest alpha-thalassaemia frequencies among Caucasian populations.
- These findings highlight the need for targeted screening and awareness programs in Cyprus.
Abstract:
The frequency of alpha-thalassaemia in Cyprus was determined with studies of haemoglobin Bart's in 1200 Greek Cypriot and 132 Turkish Cypriot newborn babies. Of the Greek newborns, 12.4%, and of the Turkish newborns, 6.8% had raised Hb Bart's (from 0.6% to 12.9% of the total haemoglobin) suggesting that they were carriers of either alpha-thalassaemia-1 or alpha-thalassaemia-2 genes. The findings suggest that the population of Cyprus has the highest frequencies of alpha-thalassaemia among Caucasian people.
