It is increasingly apparent that the identification of true genetic associations in common multifactorial disease will require studies comprising thousands rather than the hundreds of individuals employed to date. Using 2,873 families, we were unable to confirm a recently published association of the interleukin 12B gene in 422 type I diabetic families. These results emphasize the need for large datasets, small P values and independent replication if results are to be reliable.
越来越明显的是,要确定常见多因素疾病中的真正基因关联,研究需要纳入数千人,而不是迄今所采用的数百人。我们利用2873个家庭,未能在422个I型糖尿病家庭中证实最近发表的白细胞介素12B基因的关联。这些结果强调,如果结果要可靠,就需要大型数据集、小P值和独立重复验证。
