As seen in Figure 1, the “key” to the structure of the endometriosis complex SNP network are rs11031005 FSHB (causes −0.55% entropy), rs11031002 FSHB (−0.41%) and the paired antagonistic “dialogue” between rs11031005 FSHB and six other loci (rs11031002 FSHB, rs112295236 SLC22A10, rs117585797 ANO2, rs117145500 CHD9, rs727428 SHBG, rs1641549 TP53) (−0.19–−0.28%). Here, CHD9 is linked to endometriosis.
