Genetic diversity of hemoglobinopathies, G6PD deficiency, and ABO and Rhesus blood groups in two isolates of a primitive Kharia Tribe in Sundargarh District of Northwestern Orissa, India.

Tribal communities constitute about 8.2% of the total population of India. Their health needs are even larger than elsewhere in India; this study investigates the genetic diversity in relation to hemoglobinopathies, G6PD deficiency and, ABO and Rhesus (D) blood groups in two sects, i.

Intervention and prevention of hereditary hemolytic disorders in India: a case study of two ethnic communities of Sundargarh district in Orissa.

Objectives: This study was aimed at to sensitize, motivate, and screen two major vulnerable tribal communities--Bhuyan and Kharia, for hemoglobinopathies and allied hemolytic disorders, along with prospective and retrospective genetic/marriage counseling to the affected persons. For sustainability, imparting of relevant training to local paramedical staff, and to undertake periodic follow up for evaluation, intervention and clinical management through local PHCs/hospitals.

Methodology: Tribal people in Orissa live in clusters practicing inter-village marriages following tribal endogamy and clan exogamy.

Identification of a rare blood group, "Bombay (Oh) phenotype," in Bhuyan tribe of Northwestern Orissa, India.

Background: Blood group serology plays a vital role in transfusion medicine. The Bombay (Oh) phenotype is characterized by the absence of A, B, and H antigens on red cells and occurs rarely, especially in tribal populations of India.

Aims And Objectives: This is a field-based random population study in the Bhuyan tribal community.

Infant mortality and reproductive wastage associated with different genotypes of haemoglobinopathies in Orissa, India.

Background: Haemoglobinopathies, including sickle-cell disease and thalassaemia syndrome, are a group of blood diseases mostly confined to tropical and subtropical regions of the world. The spectrum of haemoglobin variants is a group of commonly encountered genetic conditions, with an average frequency of 19.32% in Orissa, varying from region to region and from community to community depending upon the type of mating practices.

Hereditary persistence of foetal haemoglobin in a tribal family of Orissa, India.

Background: The hereditary persistence of foetal haemoglobin (HPFH) is an autosomal co-dominant, rare, inherited condition. It occurs due to failure of switching off of the production of gamma-chains during the neonatal period leading to a high level of foetal haemoglobin in adult life but without any anaemia. During screening a randomly selected Paraja Bhuyan tribal population for haemoglobinopathies in the Sundargarh district of western Orissa, HPFH was detected in a family.
