A Fertility Test to Detect Ovarian Autoimmune Disease Using Human Recombinant MATER Protein
Posted Feb 28 2007 4:00pm
Description of Invention: The inventors have identified MATER, a gene that plays an important role in fertility, and have shown that antibodies against MATER protein are detected at higher frequencies in women experiencing infertility and irregular menstrual periods than in healthy women. The discovery of MATER as an important factor in autoimmune-mediated ovarian dysfunction will facilitate diagnosis and treatment of these disorders. In addition to its critical role in ovarian autoimmunity, the inventors have also discovered that the MATER gene plays an essential role in embryonic development.
The invention discloses the MATER gene, MATER protein and MATER-specific antibodies. Also disclosed are methods and kits for evaluating female infertility through detection of an abnormal autoimmune response, an abnormal MATER gene, or abnormal MATER protein expression.
Diagnostic test for women suffering from infertility or irregular menstrual periods
Tool for the study of early embryonic development
Tool for the development of MATER-based contraceptives.
Development Status: Established research test, ready for additional clinical research and commercial development.
