Ss. Mastana et al., GENETIC-POLYMORPHISM OF OROSOMUCOID (ORM) IN POPULATIONS OF THE UNITED-KINGDOM, INDIAN SUBCONTINENT, AND CAMBODIA, JPN J HUM G, 38(3), 1993, pp. 289-296
The genetic variation of the human serum orosomucoid (ORM) was investi
gated by isoelectric focusing (IEF) followed by immunofixation in 15 d
ifferent populations from East Midlands (United Kingdom), India, Sri L
anka, and Cambodia. Statistically significant differences were observe
d between various Asiatic and British populations, however differences
within Asiatic and European populations were minor. The distribution
of ORM1 alleles in populations investigated to date suggests an intere
sting east-west geographical cline. There is a suggestion that present
day wide polymorphism at the ORM1 locus may be influenced by selectio
