title: An unusually high incidence of homozygous MM in ankylosing spondylitis.
abstract: Blood types of patients admitted to the Hadassah University Hospital with ankylosing spondylitis did not differ significantly from the expected percentages among the Israeli population, except for a very high incidence (92% to 100%) of homozygous MM. Among healthy controls the incidence of homozygous MM was found to be in line with accepted values.
