We also found that three endometriosis-associated variants (Table S7) and 31 proxy loci (Table S8) have been involved in the alternative splicing regulation of 13 genes (KRTCAP3, IFT172, TRIM54, STON1-GTF2A1L, BRI3, STON1, SNX17, PPP1R21, GTF2A1L, GPN1, GCKR, FNDC4, BAIAP2L1) with an impact on endometriosis biology organs/tissues such as pituitary [3 genes] (FNDC4, IFT172, PPP1R21), adipose [9 genes] (BRI3, FNDC4, GPN1, GTF2A1L, IFT172, PPP1R21, SNX17, STON1, STON1-GTF2A1L), thyroid [4 genes] (BRI3, IFT172, KRTCAP3, PPP1R21), and adrenal glands [3 genes] (FNDC4, GCKR, IFT172). Here, BAIAP2L1 is linked to endometriosis.
