The INS gene encodes proinsulin which by cleavage of the precursor signal peptide becomes activated. Insulin is an important regulator of glocose homeostasis. Some mutations are associated with autosomal dominant diabetes those include permanent neonatal diabetes and MODY diabetes of type 10. Also, some mutations are associated with abnormal circulating insulin. Those include hyperproinsulinemia, Wakayama insulin and others.
