Mutational analysis reveals the FUS homolog TAF15 as a candidate gene for familial amyotrophic lateral sclerosis

Am J Med Genet B Neuropsychiatr Genet. 2011 Apr;156B(3):285-90. doi: 10.1002/ajmg.b.31158. Epub 2011 Jan 13.


FUS, EWS, and TAF15 belong to the TET family of structurally similar DNA/RNA-binding proteins. Mutations in the FUS gene have recently been discovered as a cause of familial amyotrophic lateral sclerosis (FALS). Given the structural and functional similarities between the three genes, we screened TAF15 and EWS in 263 and 94 index FALS cases, respectively. No coding variants were found in EWS, while we identified six novel changes in TAF15. Of these, two 24 bp deletions and a R388H missense variant were also found in healthy controls. A D386N substitution was shown not to segregate with the disease in the affected pedigree. A single A31T and two R395Q changes were identified in FALS cases but not in over 1,100 controls. Interestingly, one of the R395Q FALS cases also harbors a TARDBP mutation (G384R). Altogether, these results suggest that additional studies are needed to determine whether mutations in the TAF15 gene represent a cause of FALS.
