Protein QTL (pQTL) density for proteomics data from 2 years. X-axis represent pQTL genomic location on chromosomes. Y-axis represents pQTL density calculated on a 10Â cM sliding window. Chromosomal regions corresponding to the largest number of significant pQTLs are considered pQTL hotspots, on chromosomes 3, 5, 8, 9 for 2 years. a Protein QTL (pQTL) density from 2002 data across the genome. b Protein QTL (pQTL) density from 2003 data across the genome
