Patent number: 6924102Abstract: The present invention concerns the development of a quantitative method for the molecular diagnosis of autosomal recessive spinal muscular atrophy (SMA) by measuring the amount of cytosolic mRNA from human muscle cells. Both the procedure using radioactive material and the Enzyme-Linked Immunosorbent Assay (ELISA) nonradioactive method were developed using 32P-dCTP labeled and biotinylated nucleotide probes. The results obtained demonstrate that the measurement of mRNA could be used as a quantitative method for the molecular diagnosis of SMA. There was a perfect concordance of the results obtained between the procedure using radioactive material, the ELISA method and the single strand conformation polymorphism (SSCP) analysis regarding the negative and positive SMA samples.Type: GrantFiled: August 24, 2001Date of Patent: August 2, 2005Inventors: Khue Vu Nguyen, Charles-Michel Wolff, Philippe Poindron
