  1. Unusual features in the inheritance of ataxia telangiectasia.

    Article - En anglais

    A prevalence study of ataxia telangiectasia was conducted in the West Midlands, with a population of over 5 million.

    The prevalence in those aged 50 or less was found to be 1 in 514000 and the birth frequency to be about 1 in 300000.

    A genetic study of 47 families ascertained throughout the United Kingdom was carried out concurrently.

    A low parental consanguinity rate was found, no parents being first cousins or more closely related, whereas 10% had been expected.

    The incidence of ataxia telengiectasia in the 79 sibs of index cases was 1 in 7. These two features demonstrate that ataxia telangiectasia may not always be an autosomal recessive condition.
