Phosphoglucomutase polymorphism detected by isoelectric focusing: gene frequencies, evolution and linkage. 1979

N D Carter, and C M West, and E Emes, and B Parkin, and W H Marshall

Four alleles at the phosphoglucomutase (PGM1) locus in man have been recently demonstrated by isoelectric focusing, and in this study gene frequencies have been estimated for four populations, and significant differences have been indicated between the results. Pedigree analysis of the PGM1 and rhesus loci confirm a weak linkage in males, but none in females. An examination of PGM1 phenotypes in a range of primates shows that a proportion possess a band focusing at the same isoelectric point as human PGM1+1. We propose that all the human and primate alleles may have evolved from a common ancestral PGM1+1 locus.

D010733 Phosphoglucomutase An enzyme that catalyzes the conversion of alpha D-glucose 1-phosphate to alpha D-glucose 6-phosphate. EC 5.4.2.2. Glucose Phosphomutase,Phosphomutase, Glucose
D011110 Polymorphism, Genetic The regular and simultaneous occurrence in a single interbreeding population of two or more discontinuous genotypes. The concept includes differences in genotypes ranging in size from a single nucleotide site (POLYMORPHISM, SINGLE NUCLEOTIDE) to large nucleotide sequences visible at a chromosomal level.

D011323 Primates An order of mammals consisting of more than 300 species that include LEMURS; LORISIDAE; TARSIERS; MONKEYS; and HOMINIDS. They are characterized by a relatively large brain when compared with other terrestrial mammals, forward-facing eyes, the presence of a CALCARINE SULCUS, and specialized MECHANORECEPTORS in the hands and feet which allow the perception of light touch. Primate

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA. Animal,Metazoa,Animalia
D044383 Black People Persons having origins in any of the black racial groups of AFRICA. Note that OMB category BLACK OR AFRICAN AMERICAN is available for the United States population groups. Race and ethnicity terms, as used in the federal government, are self-identified social construct and may include terms outdated and offensive in MeSH to assist users who are interested in retrieving comprehensive search results for studies such as in longitudinal studies.
