Screening for candidate modifier genes that might be responsible for the early onset and severe course of the disease in the 25-year-old patient revealed an additional homozygous mutation of the CNTF gene not found in his yet unaffected sister. hSOD-1G93A mice were crossbred with CNTF(-/-) mice and were investigated with respect to disease onset and duration, to test the hypothesis that CNTF acts as a candidate modifier gene in FALS with mutations in the SOD-1 gene.
