Genetic structure of the Greek gypsies
Clinical Genetics
|January 1, 1979
Summary
Genetic analysis of 200 Greek gypsies reveals distinct blood group (ABO, Rhesus, MN, Duffy) frequencies compared to the general Greek population. These findings suggest ancestral ties to Indian populations and highlight the prevalence of specific hereditary diseases.
Area of Science:
- Population genetics
- Human genetics
- Medical genetics
Background:
- Gypsy populations exhibit unique genetic profiles due to historical migrations.
- Understanding genetic variations is crucial for public health and disease management.
Purpose of the Study:
- To investigate polymorphic genetic markers in a Greek gypsy population.
- To compare these genetic frequencies with other populations, including the general Greek population and Indian groups.
- To identify the prevalence of specific hereditary diseases within the studied gypsy group.
Main Methods:
- Analysis of polymorphic genetic markers: ABO, MN, Rhesus, Kell, and Duffy blood groups, hemoglobin, and ceruloplasmin.
- Survey for congenital malformations and hereditary diseases.
- Statistical comparison of genetic marker frequencies.
Main Results:
- Significant variations in ABO, Rhesus, MN, and Duffy blood group frequencies were observed compared to the general Greek population.
- The distribution of polymorphic traits showed similarities to gypsy groups in other nations and the Punjab region of India.
- Diagnosed hereditary conditions included cystic fibrosis, renal tubular acidosis, 21-hydroxylase deficiency, Holt-Oram syndrome, and homozygous beta-thalassemia.
Conclusions:
- The Greek gypsy population possesses a distinct genetic profile.
- Genetic similarities suggest ancestral links to Indian populations.
- The study identified a notable burden of specific hereditary diseases within this community, underscoring the need for targeted health interventions.
