Other genes that might influence the T1D risk include IL2RA (encoding α subunit of the IL-2 receptor), interleukin genes (mainly IL-4 and IL-13), PTPN2 (protein tyrosine phosphatase, non-receptor type 2), IFIH1 (interferon-induced helicase), BACH2 (basic leucine zipper transcription factor 2), GLIS3 (Gli-similar 3 protein), and ubiquitin-associated and SH3 domain-containing protein A (UBASH3A) genes (Table 4) [39,40]. The gene discussed is PTPN2; the disease is type 1 diabetes mellitus.
