Under the linkage peak of Chr6 QTL for atherosclerosis, Ath54, 41 protein-coding genes were polymorphic between BALB and LP strains, including Jazf1, Creb5, Tril, Cpvl, Chn2, Wipf3, Scrn1, Fkbp14, Plekha8, Mturn, Znrf2, Nod1, Ggct, Gars1, Crhr2, Inmt, Mindy4, Aqp1, Adcyap1r1, Neurod6, Itprid1, Ppp1r17, Pde1c, Lsm5, Avl9, Kbtbd2, Fkbp9, Nt5c3, Ppm1k, Herc6, Pyurf, Lancl2, Vopp1, Abcg2, Herc3, Fam13a, Gprin3, Snca, Mmrn1, Ccser1, and Grid2. This evidence concerns the gene AQP1 and atherosclerosis.
