Abstract
THE abnormal assembly and accumulation of neurofilaments (NF) in the perika rya and proximal axons of motor neurones is a characteristic of ALS. Deleti ons in the KSP repeat region of the NF-H gene have previously been reported in seven patients with sporadic ALS. Here we report the identification of a novel 84 bp insertion in the NF-H gene. This leads to an extra four KSP r epeat elements in a highly conserved repetitive region of the gene. Althoug h neurofilament mutations are only associated with a very small proportion of ALS cases, this insertion provides further support of a role for neurofi laments in the pathogenesis of ALS.
