Figure 2From: Balancing selection is common in the extended MHC region but most alleles with opposite risk profile for autoimmune diseases are neutrally evolvingSchematic representation of the gene regions we resequenced in TAP2 , TRIM10/TRIM40 , CDSN/PSORS1C1 and BTNL2. Transcribed regions are shown in grey; different transcripts either from the same or from different genes are shown separately. The direction of transcription is indicated by the arrows. The location of SNPs with opposite risk profile is reported.Back to article page
