FIG4 gene mutations in neurodegeneration
View Patent ↗The present invention relates to neurological disease, in particular to mutations in the FIG4 gene. The present invention also provides assays for the detection of variant FIG4 alleles, and assays for detecting FIG4 polymorphisms and mutations associated with disease states such as ALS.
1. A method for detecting the presence of a variant FIG4gene in a biological sample from a human subject, comprising: (a) contacting a FIG4 gene in a biological sample from a human subject with a detectably labeled probe under high stringency conditions wherein the detectably labeled probe specifically hybridizes to a variant FIG4 gene but not with a non-variant FIG4 gene, and (b) detecting a hybrid resulting therefrom, wherein said variant FIG4 gene comprises a mutation of c.547C>T.
2. The method of claim 1 , wherein said biological sample is selected from the group consisting of a blood sample, a tissue sample, a urine sample, a DNA sample, and an amniotic fluid sample.
3. The method of claim 1 , wherein detecting the presence of a variant FIG4 gene comprises amplifying one or more exons or introns of FIG4.
4. The method of claim 3 , wherein said exons or introns are selected from the group consisting of exon 6, exon 12 and intron 1.
5. The method of claim 1 , wherein the probe is detectably labeled with an enzymatic, fluorescence, radioactive and/or luminescent label.
