...N. Saha; J.S.H. Tay; B. Carritt Three different ethnic groups from Singapore comprising 79 Chinese, 34 Malays and 23 Indians of Dravidian origin, were investigated for the Hind III RFLP at the DNF15S2 locus. The three populations had very similar allele frequencies and the frequency of rarer(S...

...N. Saha; S.P. Bhattacharyya Autopsy liver samples from 244 Chinese, 119 Malays and 136 Indians were screened for glutamate-pyruvate transaminase (GPT) subtypes by starch-gel electrophoresis and isoelectric focusing at pH 5–7. Altogether, ten phenotypes controlled by four alleles ( GPT 1 , GPT 2A...

...N. Saha A total of 215 subjects comprising 95 Chinese, 66 Malays and 54 Indians were investigated for restriction fragment length polymorphisms of the tissue-type plasminogen activator (PLAT) gene at an Eco Rlsite using the probe ptPA-4352. The phe-notypic distribution showed a good agreement...

...M. Shintani; K. Minaguchi; K.A. Lim; M. Hashimoto; K. Suzuki Salivary proline-rich protein (PRP) polymorphism, PRH1, PRH2, Ps, Pm (PmF), PmS and Gl, were investigated in three ethnic groups in Singapore: Chinese, Malays and Indians. The phenotype and gene frequencies were presented and comparison...

... of southeast Asia comprising 194 Chinese, 159 Filipinos and 73 Dravidian Indians were investigated for serum paraoxonase polymorphism. The frequency of PON*B was found to be 0.14 in the Chinese, 0.04 in the Filipinos and 0.18 in Dravidian Indians. The distribution of the PON phenotypes was at Hardy-Weinberg...

...S.P. Bhattacharyya; N. Saha Mitochondrial malic enzyme (EC 1.1.1.40; ME M ) was examined by starch-gel electrophoresis on post-mortem brain samples from 453 unrelated subjects of either sex comprising 161 Chinese, 150 Indians and 113 Malays and 29 from other racial groups. The estimated gene...

...N. Saha A total of 627 subjects comprising 455 Chinese, 127 Dravidian Indians and 45 Malays were investigated for serum Apo A-IV polymorphism. The frequency of Apo A-IV*2 was found to be significantly higher (p& < 0.001) in Indians (0.043) compared to that in the Chinese (0.010) and Malays...

...Lillian E. Dyck Three methods were employed to assess whether human volunteers (Caucasian, Asian or Cree Indian) possessed the typical or atypical mitochondrial aldehyde dehydrogenase (ALDH2) isozyme. These methods were: (1) questionning individuals about facial flushing responses following alcohol...

...Leila Karazawa Guerra; Ian Robert Rehfeldt; Marcilene Teixeira Lima; Maria Luiza Petzl-Erler; Iara J. Taborda de Messias The distribution of C3 and BF variants was determined in a sample of 239 Kaingang Indians. The corresponding gene frequencies were as follows: BF*S = 0.9393, BF*F = 0.0356, BF...

... aldehyde as substrate. Furfuraldehyde is readily oxidized while propion-aldehyde is used to a lesser extent. One genetic variant was seen among 71 Chinese stomach specimens while another different variant was found among 33 Indian samples. Hum. Hered. 31: 74-77 (1981) Stomach Aldehyde Dehydrogenase: Report...

...S.G. Tan; Y.S. Teng A total of 640 Malaysians, 355 of Malay, 155 of Chinese, and 130 of Indian ancestries have been examined for saliva acid phosphatases. The three ethnic groups were polymorphic for saliva acid phosphatase A (Sap-A) and saliva acid phosphatase B (Sap-B). The gene frequencies were...

...Y.S. Teng; S.G. Tan Acid α -glucosidase from the placenta was electrophoretically surveyed in a total of 633 Malaysians, 236 of Malay, 261 of Chinese and 136 of Indian ancestries. A new variant, α -glucosidase 3-1 was observed in 1 Malay and 3 Indians. A polymorphism for this enzyme was observed...

.... These data are consistent with the hypothesis of a ‘common ancestral background’ in Indian populations whatever the degree of socio-cultural and linguistic diversity, and the geographical distances. (2) Specific traits due to the frequency of alleles in some systems confer to that tribe a particular position...

...Q.B. Welch; Luan Eng Lie-Injo; J. Ganesan 944 adenosine deaminase phenotypings of Malay, Chinese, and Indian blood donors and newborns at Kuala Lumpur, Malaysia, yielded ADA 1 gene frequency estimates of 0.885 for the Malays, 0.939 for the Chinese, and 0.853 for the Indians. © 1975 S. Karger AG...

...M.L. Choong; E.S.C. Koay; M.C. Khaw; T.C. Aw The allele frequencies for the apolipoprotein B (apo B) 5′-Ins/Del and 3′-VNTR polymorphisms varied significantly (p < 0.01) among Singaporeans of Chinese, Malay and Indian descent. We calculated the unbiased expected heterozygosities for the 5′-Ins...
