Gene mutations in Janus kinase/signal transducer and activator of transcription signaling pathway can promote the occurrence of type 2 diabetes mellitus and autoimmune diseases. We report two type 2 diabetes mellitus patients (mother and her adult son) with concomitant Hashimoto ' s thyroiditis and autoimmune diseases. The son was diagnosed with systemic sclerosis and antiphospholipid syndrome, while the mother was diagnosed with primary biliary cholangitis. Both diagnoses occurred simultaneously. These cases highlight that in clinical practice, careful symptom assessment, thorough history-taking, standardized physical examination, and obtaining a detailed family history are important. This reduces misdiagnosis and missed diagnosis rates, enabling early diagnosis and treatment, thereby improving patient outcomes. While genetic testing is not performed in these two patients, this represents a potential direction for future research.
