Genetic Dissection of Complex Traits

TLDR
The current state of the genetic dissection of complex traits is summarized in this paper, which describes the methods, limitations, and recent applications to biological problems, including linkage analysis, allele-sharing methods, association studies, and polygenic analysis of experimental crosses.
Abstract
Medical genetics was revolutionized during the 1980s by the application of genetic mapping to locate the genes responsible for simple Mendelian diseases. Most diseases and traits, however, do not follow simple inheritance patterns. Geneticists have thus begun taking up the even greater challenge of the genetic dissection of complex traits. Four major approaches have been developed: linkage analysis, allele-sharing methods, association studies, and polygenic analysis of experimental crosses. This article synthesizes the current state of the genetic dissection of complex traits—describing the methods, limitations, and recent applications to biological problems.

TL;DR: Since PCOS usually has a menarchal age of onset, this makes it a particularly appropriate disorder in which to examine the ontogeny of defects in carbohydrate metabolism and for ascertaining large three-generation kindreds for positional cloning studies to identify NIDDM genes.

Transmission test for linkage disequilibrium: the insulin gene region and insulin-dependent diabetes mellitus (IDDM).

TL;DR: The statistical basis for this "transmission test for linkage disequilibrium" (transmission/disequilibrium test] is described and the relationship of this test to tests of cosegregation that are based on the proportion of haplotypes or genes identical by descent in affected sibs is shown.

Precision mapping of quantitative trait loci.

TL;DR: A new method of QTL mapping is proposed and analyzed in this paper by combining interval mapping with multiple regression, an interval test in which the test statistic on a marker interval is made to be unaffected by QTLs located outside a defined interval.
