R. Scozzari et al., NOVEL TETRANUCLEOTIDE REPEAT POLYMORPHISM IN THE HUMAN ADENOSINE-DEAMINASE GENE - INTERETHNIC COMPARISON OF 3 MAJOR HUMAN GROUPS, Human biology, 68(2), 1996, pp. 315-320
A new tetranucleotide repeat polymorphism was revealed at the human ad
enosine deaminase (ADA) locus by using the polymerase chain reaction a
nd denaturing polyacrylamide gel electrophoresis. Allele frequencies w
ere estimated in seven populations from three major ethnic groups. Het
erozygosity values were calculated and found to differ significantly b
etween Africans and non-Africans.
