A DNA pooling strategy for family-based association studies

Abstract

Genome-wide association scans for disease susceptibility genes of complex diseases require genotyping on a massive scale. A DNA pooling strategy for family-based association studies is described, which is robust to population stratification biases and to errors in pooling. It can achieve a statistical efficiency of 0.95 with ∼1 of 8 or fewer genotyping efforts, and an efficiency of 0.90 with ∼1 of 16 or fewer efforts compared with individual genotyping. The pooling method described in this article provides a tradeoff between genotyping efforts and subject recruitment efforts. Copyright © 2005 American Association for Cancer Research.
