title: Detection of a restriction site polymorphism within the human alpha-globin gene complex.
abstract: A mutant Rsa I restriction endonuclease site of high frequency has been identified in individuals of German, Greek, Italian, and Turkish origin. The mutation was found within the alpha-globin gene complex and is located 0.7 kb 5' to the alpha 2-globin gene. In individuals of central European origin 34 out of 58 chromosomes exhibited the alpha-gene linkage to the presence of the polymorphic site, and thus a preliminary estimate of the gene frequency for this allele would be 0.59. DNA analysis data of individuals derived from Mediterranean populations indicate a distribution of this polymorphic marker in similar frequencies.
