The invention broadly relates to the use of the Active in the causal treatment of a disease caused by axonal demyelination, in which the Active maintains the integrity of myelination (for example by promoting remyelination, and/or preventing demyelination, of the axonal sheaths). The invention is particularly directed to the causal treatment of CNS demyelination diseases, for example MS, especially primary progressive MS and/or relapse remitting MS, and PNS demyelination diseases, for example Charcot-Marie-Tooth Disease. The Active of the invention may be suitably administered when a patient is in relapse (i.e. upon relapse), and be continued while the patient is in relapse, with a view to attenuating the severity of the relapse, and/or accelerating disease remission. Alternatively, the Active may be administered continuously with a view to prolonging the remission period, and/or attenuating the severity of the relapse, and/or preventing relapse. The invention also relates to the use of the Active as a treatment for symptoms of demyelination disease, especially MS, selected from vision deficits, motor control deficits, and sensation deficits.

Animals with mutations in COL4α4 present with autosomal recessive Alport Syndrome (ARAS). Through sequencing of COL4α4, the mutation causative for ARAS in the English Cocker Spaniel (ECS) has been identified. The resulting protein is severely truncated due to a premature stop codon in exon 3. This nonsense mutation occurs in the 7S domain and also causes the loss of the entire collagenous and NC1 domains of the protein. Methods for the identification of animals that harbor a mutation in the COL4α4 gene are described. Mutations in the COL4α4 gene can be identified from any biological sample such as a cell or tissue that contains genomic DNA. Methods for identifying single nucleotide polymorphisms (SNPs) that are inherited with the disease are also described. A microsatellite marker that segregates with ARAS is also described that was identified using linkage disequilibrium mapping.
