The results showed that there were statistically significant differences between the two groups in terms of whether they had neurological hearing impairment, whether they had clinical manifestations of multiple systems, whether they were maternal inheritance, and whether they had diabetes ketoacidosis (P < 0.05).There was no statistically significant difference in the age of onset, body type, insulin related antibody status, and duration of disease between the two groups of patients, with P values > 0.05 (Table 2). The gene discussed is INS; the disease is diabetes mellitus.
