Genetic connection of carotid atherosclerosis with coat color and body weight in an intercross between hyperlipidemic mouse strains.

ABSTRACT: Atherosclerosis in the carotid artery is a major cause of ischemic stroke and has a strong genetic component. The aim of this study was to identify genetic factors contributing to carotid atherosclerosis. One hundred fifty-four female F2 mice were generated from an intercross between LP/J and BALB/cJ Apoe-null (Apoe^-/-) mice and fed 12 wk of Western diet. Atherosclerotic lesions, body weight, and coat color were measured and genotyping was performed using miniMUGA genotyping arrays. A significant quantitative trait locus (QTL) on chromosome (Chr) 7, named Cath20, and five suggestive QTL on Chr 6, 12, 13, 15, and X were identified for carotid lesions. Three significant QTL, Bwfq2, Bw1n, Bwtq6, on Chr 2, 7, and 15 were identified for body weight. Two si
