Multiple genome-wide association studies have shown that the single-nucleotide polymorphism (SNP) rs2281808 TT variant, present within the signal regulatory protein gamma (SIRPG) gene, is associated with autoimmune diseases, such as type 1 diabetes.
Multiple GWAS studies have shown that the SNP rs2281808 TT variant, present within the SIRPG gene, is associated with autoimmune diseases, such as type 1 diabetes.
Furthermore, many AID risk SNPs from GWAS have been subsequently fine-mapped in recent Ichip projects, and fine-mapped AID SNPs overlapped with the thymic eQTLs within RNASET2 and SIRPG Finally, in all the eQTL regions, except C2orf74, SNPs underlying the thymic eQTLs were predicted to interfere with transcription factors important in T cell development.
