Polymorphisms of alpha-1-acid (orosomucoid), alpha-2-HS-glycoproteins and alpha-1-B among the Parsis of India.

Genetic polymorphisms of plasma alpha 1-acid glycoprotein (oro-somucoid, ORM), alpha 2-HS-glycoprotein (A2HS) and alpha 1-B-glycoprotein (alpha 1B) were studied in a group of Parsis in Bombay, India. The frequencies of ORM1*1, ORM1*2 and ORM1*3 were found to be 0.636, 0.356 and 0.008, respectively. A2HS*1, A2HS*2 and A2HS*3 frequencies were 0.855, 0.135 and 0.010, while the frequencies of A1B*1 and A1B*2 were 0.881 and 0.119, respectively. The phenotype distribution at all three loci was at Hardy-Weinberg equilibrium. The ORM2 locus was monomorphic in the Parsis.

Distribution of transferrin and group-specific component subtypes among Parsis of India.

Transferrin and group-specific component subtypes were studied by isoelectric focusing of sera from 253 Parsis in India. The frequencies of TfC1, TfC2, TfC3 and TfC4 were found to be 0.8083, 0.1719, 0.019 and 0.0020, respectively. TfB was present in a frequency of 0.0059. The frequencies of Gc alleles were found to be 0.4478 for GcIF, 0.3875 for GcIS and 0.1647 for Gc2. The gene frequency of GcIF was rather high in comparison with Iranian and Indian populations.

G-6-PD and haemoglobin variants among twelve endogamous Dhangar castes of Maharashtra, India.

Incidence of haemoglobin variants and G-6-PD deficiency among 1385 males belonging to 12 endogamous Dhangar castes of Maharashtra, India, have been reported. Of the 12 castes studied 11 lacked the allele for G-6-PD deficiency; 2.7% of the Thellaris were found to be deficient. Haemoglobin Hb-D trait is found in 2 of the 12 castes; the incidence among Ahirs and Hatkars being 0.82% and 1.91%, respectively. One case of Hb-J among the Ahirs, and 2 examples of thalassaemia trait, one each among Ahirs and Gadharis, have been detected. The low incidence of observed G-6-PD deficiency and the detection of Hb-D and J traits, as well as thalassaemia have been discussed in the light of the nomadic way of life of some of the Dhangar castes and prevalence of malaria in the region they occupy. The data strongly suggest that the Dhangars arrived in Maharashtra in the recent past from northwest.

A population genetic study of the Vania Soni in Western India.

A total of 267 blood samples from persons belonging to the Shrimali Vania Soni caste group in Gujarat State, Western India have been analyzed for 6 blood group, 4 serum protein and 19 red cell enzyme systems, for haemoglobin and beta-thalassaemia and for red-green colour blindness. A number of rare genetic variants were detected, including a unique electrophoretically fast variant of superoxide dismutase. Genetic distance comparisons with other caste groups in Gujarat State show that Vania Soni from Surat are a distinctive group clustering with another subdivision of the Vania. The remaining Vania Soni cluster together and are distinct from the other caste groups examined in Gujarat. However, on the basis of individual genetic markers the Vania Soni appear not to be genetically differentiated in any remarkable way from other Hindu populations in western and northern India.
