The resequencing of 13 IFNA genes in 32 T1D cases identified 152 polymorphisms (see Additional file 1), 144 of which were SNPs and eight were deletion/insertion polymorphisms (DIPs); of these, 64 SNPs and eight DIPs were novel when compared with dbSNP build 124. The gene discussed is IFNA2; the disease is type 1 diabetes mellitus.
