title: Chromosomal studies in healthy blood donors with IgA deficiency.
abstract: Chromosomal analysis was performed in 70 asymptomatic blood donors found over a 5-year period in a large screening programme to be IgA deficient. No abnormalities were found in any of these individuals in relation to their chromosomal constitution and, in particular, chromosome 18 was normal in all individuals. A further 10 symptomatic individuals with IgA deficiency also showed a normal chromosomal constitution with no abnormalities of chromosome no. 18.
