can you give me some symptoms signs of diabetes

Wolfram syndrome is an autosomal recessive neurodegenerative disorder first evident in childhood. It consists of diabetes insipidus, diabetes mellitus, optic atrophy, and deafness, hence the acronym DIDMOAD. It is due to mutations in a gene named WFS1, which encodes a 100.3 KDa transmembrane protein localized in the endoplasmic reticulum. The function of the protein is not known. The diabetes mellitus, which is nonimmune and not linked to specific HLA antigens, usually presents in the first decade together with the optic atrophy. Cranial diabetes insipidus and sensorineural deafness develop during the second decade in 60-75% of patients. Ureterohydronephrosis, neurogenic bladder, cerebellar ataxia, peripheral neuropathy, and psychiatric illness develop later in many patients. (current MD&T 2005)
