An Exploratory Study of the Non-communicable Disease Risk Factors in an Endogamous Caste Population of Reddys from Tirupati, India
Surveillance of risk factors may help in devising interventions for reducing the burden of non-communicable diseases (NCDs). Most of the studies on NCD risk factors were conducted without taking into consideration the social units of India, like castes and tribes. In this study, an attempt was made to study the NCD risk factors in an endogamous Reddy caste population of Tirupati, India. A sample of 105 adult women and 94 adult men were recruited …
Molecular genetic perspectives on the Indian social structure
For historical reasons, the Indian subcontinent is endowed with enormous ethnic, cultural, and genetic heterogeneity of its people. In the process of understanding the dynamics and sociocultural complexity of Indian society, anthropologists have come up with a number of hypotheses involving certain social/cultural processes that may modulate evolutionary processes. In this article, we outline some of those hypotheses and present molecular genetic…
Asian and non‐Asian origins of Mon‐Khmer‐ and Mundari‐speaking Austro‐Asiatic populations of India
In the present study, we analyzed 1,686 samples from 31 tribal populations of India for the mitochondrial DNA 9‐base‐pair deletion/insertion polymorphism, and characterized them based on the relevant mitochondrial DNA coding‐region single nucleotide polymorphisms and hypervariable region I motifs, to test the genetic origins of the ethnically and linguistically heterogeneous Austro‐Asiatic tribes of India. A comparative analysis of our results wi…
Genetic diversity within a caste population of India as measured by Y‐chromosome haplogroups and haplotypes
The extent of population subdivision based on 15 Y‐chromosome polymorphisms was studied in seven subcastes of the Golla (Karnam, Pokanati, Erra, Doddi, Punugu, Puja, and Kurava), who inhabit the Chittoor district of southern Andhra Pradesh, India. These Golla subcastes are traditionally pastoralists, culturally homogeneous and endogamous. DNA samples from 146 Golla males were scored for seven unique event polymorphisms (UEPs) and eight microsatel…
Microsatellite Diversity in Andhra Pradesh, India
DNA samples of 948 individuals belonging to 27 populations from southern Andhra Pradesh were analyzed for nine AmpFlSTR Profiler Plus loci. The nature and extent of genomic diversity within and between these populations have been examined with reference to socioeconomic and geographic affiliations. The results suggest that the average heterozygosity is uniformly high in these populations (>0.80) and that the patterns of allele distributions are s…
Genetic heterogeneity in northeastern India
We critically examined the gene frequency data for 11 genetic markers commonly available in the literature for 22 populations of northeastern India in the light of their geographic, linguistic, and ethnic affiliations. The markers investigated were three blood groups (A 1 A 2 BO, MNS, and Rh), four serum proteins (KM, Gc, Hp, and Tf), and four enzyme systems (AP, AK, EsD, and Hb). The neighbor‐joining tree and multidimensional scaling of the dist…
