Phosphoglucomutase (PGM) and group-specific component (Gc), isoelectric focusing sub-types among Zoroastrians of Iran

A total of 243 and 236 red cell and serum samples from the Zoroastrians of Iran were sub-typed by isoelectric focusing for the red cell enzyme phosphoglucomutase locus 1 and the group-specific component respectively and the phenotype and gene frequency values were calculated. Comparison of the results with those of examinations performed on African, Asian and European population shows that for both the PGM and Gc systems Zoroastrians show similarity to western populations and differ from middle-eastern populations.
