Among the 20 genes related to GCA survival and the 36 genes related to GNCA survival were just three genes that overlapped – CTSB, LEPR, and LIPF. The most significant statistical associations observed with survival (P<0.01 in log-rank tests) were for COL11A1, CTSB, and MMP9 for GCA, and ADA, ESRRG, and LHFP for GNCA. This evidence concerns the gene ESRRG and temporal arteritis.
