Association studies using familial cases: an efficient strategy for identifying low-penetrance disease alleles.

Abstract excerpt

Low-penetrance alleles are likely to contribute to inherited susceptibility to many complex traits. Such alleles will rarely generate multiple-case families and are therefore difficult or impossible to identify through genetic linkage analyses. The search for low-penetrance alleles has therefore centred on comparing the frequencies of specific alleles in cases and controls via an association study. With recent...
