Study of a large Anglo-Saxon family with beta-thalassaemia trait.
Study of a large Anglo-Saxon family with beta-thalassaemia trait revealed evidence of consanguinity, moreover both branches of the family shared a Spanish ancestor. The manifestations of the disorder were varied in severity and yet the degree of severity appeared to breed true within any individual part of the family. Our explanation for the inheritance pattern observed in the family was to postulate the existence of two non-allelic genes influencing the rate of beta-chain synthesis.
