Immunoglobulin Gm and Km genetic markers in Vietnamese. 1978

M H Tran, and M Daveau, and S M Dumitresco, and L Rivat

The distribution of the G1m (1,2,3,17), G2m(23), G3m(5,10,11,13,14,15,21,28) and Km (1,2) allotypic markers has been examined in 122 unrelated Vietnamese subjects originating from all regions of Vietnam. The 13 observed phenotypes have been explained by means of 8 haplotypes: 5 'major' ones (which are also known to be usual in all other reported Mongoloid populations) and 3 'minor' ones. Consideration of gene frequencies allows easy integration of Vietnamese within the south-north cline of Gm haplotype distribution in East Asia, where they insert between Southern Chinese, on one hand, and Singapore as well as South Central Chinese on the other hand. The observed Km10.290 frequency value revealed to be of the same order of magnitude as the values reported for most other non-Thai Mongoloids.

UI MeSH Term Description Entries
D007136 Immunoglobulins Multi-subunit proteins which function in IMMUNITY. They are produced by B LYMPHOCYTES from the IMMUNOGLOBULIN GENES. They are comprised of two heavy (IMMUNOGLOBULIN HEAVY CHAINS) and two light chains (IMMUNOGLOBULIN LIGHT CHAINS) with additional ancillary polypeptide chains depending on their isoforms. The variety of isoforms include monomeric or polymeric forms, and transmembrane forms (B-CELL ANTIGEN RECEPTORS) or secreted forms (ANTIBODIES). They are divided by the amino acid sequence of their heavy chains into five classes (IMMUNOGLOBULIN A; IMMUNOGLOBULIN D; IMMUNOGLOBULIN E; IMMUNOGLOBULIN G; IMMUNOGLOBULIN M) and various subclasses.
