Abstract: Use of the large form of human 2?,5?-Oligoadenylate Synthetase (OAS3) for diagnosis, prevention and treatment of infection with positive-sense single-stranded RNA viruses and for prediction of human genetic susceptibility to positive-sense single-stranded RNA virus-related diseases.

Abstract: The present invention relates to a method of diagnosis of neonatal diabetes, congenital hypothyroidism and congenital glaucoma, comprising detecting the presence of a mutation in the GLIS3 gene and to a method for preparing functional pancreatic beta-cells by culturing human multipotent or pluripotent cells, such as embryonic stem cells (ES-cells) or human somatic stem cells in a culture medium comprising a effective amount of GLIS3 to induce said cells differenciation into functional pancreatic beta-cells producing insulin. It also relates to a pharmaceutical composition comprising GLIS3 as active ingredient.

Abstract: The present invention is directed to isolated variant nucleic sequence of genomic sequence encoding the translation initiation factor 2 alpha kinase 3 (EIF2AK3) capable of inducing the Wolcott-Rallison syndrome (WRS) or affecting the risk of developing diabetes and/or other pathology related to WRS, and to the polypeptide encoded by these sequences. The invention also relates to vectors or transformned cells containing these sequences. The present invention further concerns method and kit for determining in a subject the risk of developing diabetes and/or other pathology related to WRS and method for selecting compound which can be used as medicament for the prevention and/or treatment of these pathologies.
