Abstract:
:A survey of more than 21 000 haemolysates from blood samples collected in various parts of south and southeast Asia, Australasia and the Western Pacific and examined in this laboratory has revealed several new alleles controlling variants of sMDH; in addition, further information has been provided on the distribution of sMDH3 in New Guinea. Two of the variant alleles, sMDH3 and sMDH6, achieve polymorphic frequency in various populations. sMDH3 is widely distributed in New Guinea, with highest frequencies in the Eastern Highlands. The pattern of its distribution suggests the mutant arose originally in a Papuan-speaking population. So far, sMDH6 has been detected only in Micronesians from a number of islands in the Carolines. A single example of another new variant, sMDH 5-1, and two examples of a slow variant, sMDH 7-1, were detected in samples from Iran and Singapore, respectively. No examples of mMDH variants were found in a total of 652 placental extracts from Papua New Guinea and Australia.
