Abstract

Bloom syndrome is more common in individuals of Ashkenazi Jewish descent than in any other population, and one particular mutation in the Bloom syndrome gene, blm(Ash), is homozygous in nearly all Ashkenazi Jewish persons with Bloom syndrome. We have determined the frequency of blm(Ash) in 1491 Ashkenazi Jewish persons with no known history of Bloom syndrome and found that 1 in 107 persons was heterozygous. Although not common, genetic screening for Bloom syndrome is feasible in this population.
