Multiple sclerosis (MS) is a complex trait with a significant genetic component. Recent work has implicated the ST8SIA1 gene, encoding a ganglioside synthase, in susceptibility to the disease, perhaps with a parent-of-origin effect. In this investigation of 1318 MS patients from 756 Canadian families, we analysed the transmission of the four single nucleotide polymorphisms in ST8SIA previously shown to be associated with MS. No significant association was found in the entire sample or when stratifying by transmitting parent, indicating that this gene plays little or no role in susceptibility to MS in the Canadian population.
