Abstract

Consanguinity analysis can be performed in populations comprising collections of genetic isolates, and the resulting estimates can be valid and useful in phenotypes caused by numerous recessive genes, such as mental retardation and congenital nerve deafness. Maximum likelihood methods are presented for estimating gene frequency and proportions of homozygous cases of morbid phenotypes in such populations.

摘要

血缘关系分析可在由遗传隔离群集合组成的人群中进行,所得估计值对于由众多隐性基因引起的表型(如智力迟钝和先天性神经性耳聋)可能是有效且有用的。本文提出了最大似然法,用于估计此类人群中致病表型纯合病例的基因频率和比例。
