ALG1L2 and proctitis: The ALG1L2 mapped to the significant CNV region on chr3:129690192–129,896,364 (along with TRH and FAM86HP) was also found to be associated with proctitis in the transcriptomic analysis of whole-blood tissue, while the other two genes (TRH & FAM86HP) were not predicted in either of the two tissues.
