The gene symbol is listed, along with an “X” to indicate if it was an eQTL or a non-synonymous coding SNP. Citations are provided for genes that have been previously reported in selectively bred mice, if a knockout mouse exists with an abnormal FC phenotype, or if additional evidence from rodent or human studies provides support
