This study suggested several T1D susceptibility genes that also contribute to TPOAb levels, including STAT4, BACH2, UBASH3A, PTPN22, CTLA4, IL2, RASGRP1, SH2B3, FCRL3, FCRL1, IL2-IL21 and SPPL332, pointing that there are possibly more undiscovered TPOAb and TgAb loci that are also involved in the development of other non-thyroid diseases characterized by the presence of thyroid antibodies. Here, IL2 is linked to thyroid gland disorder.
