An 18 mer sequence in a rat 1.3 kbp EcoRI repeat detects genetic polymorphism in humans

DNA fingerprinting involves the typing of an individual's DNA content to produce somatically stable,individual-specific DNA fingerprints. This technique often uses hypervariable minisatellite (HVMS) sequences as the fingerprinting probe and has found extensive use in several disciplines. Recently, we sequenced a 1.3 kbp EcoRI repetitive DNA fragment, shown to harbour the meiotic DNA repair site(s) of rat pachytene spermatocytes. This 1.3 kbp clone contained four sequences sharing high homology to the various HVMS sequences reported in the literature. Here we show that one of the sequences can indeed detect polymorphism in human individuals and can be used for DNA fingerprinting

Inbreeding in the state of Karnataka, South India

The inbreeding patterns and coefficient of inbreeding (F) of 3,350 new-borns in Bangalore, Karnataka were determined. A total of 29.24% were born of consanguineous marriages, F = 0.02313. Inbreeding was most common among the Hindus: 23.56% of their marriages were uncle-niece, F for the group was 0.02670

Relation between Glasgow outcome score extended (GOSE) and the EQ-5D health status questionnaire after head injury

The degree of consanguinity of the progeny, the number of live-borns and number of living children were determined in 3350 marriages in Bangalore, Karnataka. The coefficient of inbreeding (F) was 0.02308, higher than in comparable, urban populations in other South Indian states. No significant differences were found between the consanguineous and non-consanguineous groups in numbers of live-born or living children nor was there any consanguinity-related trend with respect to these parameters

Consanguinity, twinning and secondary sex ratio in the population of Karnataka, South India

Consanguineous marriages are strongly favoured in the state of Karnataka. Of 65492 marriages studied 33·07% were consanguineous, equivalent to a coefficient of inbreeding (F) of 0·0298. The twinning rate was low, 6·9 per thousand, whereas the secondary sex ratio, 0·5221, was higher than in comparable major human populations. Consanguinity exerted no significant effect on either parameter. The results also indicate that consanguinity is not associated with excess antenatal losses and suggest the possibility of enhanced selection against mutations at X chromosome loci

Neonatal screening for amino acidaemias in Karnataka, South India

Consanguineous marriages are strongly favoured among the peoples of South India. Because of the potential genetic risks resulting from inbreeding, a neonatal screening project was established in 1980 in the state of Karnataka for the identification of amino acidaemias. To date, blood samples obtained by toe-stab from 98 256 neonates have been tested by thin layer chromatography, with 46 single and 70 general amino acidaemias detected. The coefficients of inbreeding (F) for the two groups of neonates were 0.0336 and 0.0350, by comparison with a previously determined F value for the general, new-born population of 0.0298. The most common single abnormality detected was tyrosinaemia, with spontaneous resolution in the majority of cases
