Erythrocyte superoxide dismutase in different racial groups in Malaysia

Abstract

A rare electrophoretic variant of superoxide dismutase (SOD) was found in one Filipino of 146 Filipinos, 1382 Malaysians and 816 Indonesians examined. The variant consists of two usual bands and two slower migrating bands similar to those reported earlier. Superoxide dismutase variants are common among people of certain localized regions in Europe, however, this is the first report of such a variant occurring in people of non-European origin.
