Genetic studies among the endogamous groups of Lohanas of North and West India.

Four groups of Lohanas, belonging to the Gujarati, Sindhi and Punjabi were studied for various genetic markers. Lohanas have higher B than A and low Rh(D) negative (1.65-4.64%). The Hp1 gene ranges from 0.1557 to 0.2639; Gm1 is lower (0.34-0.55) than in other populations in Southern India. G-6-PD deficiency was prevalent in 3-8%. All the four groups have a high incidence of the thalassaemia trait and possess Hb-D. Hb, J, and L were also observed in two groups. Data was analysed for intergroup differences.

Genetic studies among endogamous groups of Saraswats in Western India.

Three groups of Saraswat Brahmans in Western India and a group of Goan Catholics ethnologically related to Saraswats were studied for various genetic markers. Saraswats have higher A than B with an Rh(D)-negative incidence ranging from 10 to 17%. All the groups have low incidence of G-6-PD deficiency (up to 1%). Incidence of thalassaemia trait ranges from 1 to 6%. Gm(1) was present in 85-87%. Intergroup differences suggest genetic closeness between the various groups with genetic distance ranging from 0.8 to 1.5. Genetic relationship between Goan Catholics and Chitrapur Saraswats confirms the ethnological and historical evidence of relationship between the two groups.

Hemoglobin-A2-Coburg or alpha2delta2116Arg leads to His (G18).

Hemoglobin-A2-Coburg or alpha2delta2-116 Arg leads to His (G18) has been found in members of a family of Sicilian origin. The propositus is heterozygous for hemoglobin-A2-Coburg as well as for beta-thalassemia, and family data indicate that the gene for the delta-Coburg chain is in trans of the beta-thalassemia determinant.
