Clinical demographics of multiplex families with multiple sclerosis. Multiple Sclerosis Genetics Group. 1998


The demographic and clinical characteristics of 89 multiplex families whose affected members meet proposed diagnostic criteria for multiple sclerosis (MS) genetic research are described and compared with 425 sporadic cases of MS and other published collections of MS multiplex families. The proportion of affected multiplex family members who experienced gradual progression of disability from onset (primary progressive MS) is lower than reported by other investigators. Different phenotypes of MS may reflect genetic heterogeneity that may partially explain inconsistencies in the results of genetic linkage studies. Clinical details of affected multiplex family members must be described so that comparisons of genetic results across studies can be properly interpreted.

D009103 Multiple Sclerosis An autoimmune disorder mainly affecting young adults and characterized by destruction of myelin in the central nervous system. Pathologic findings include multiple sharply demarcated areas of demyelination throughout the white matter of the central nervous system. Clinical manifestations include visual loss, extra-ocular movement disorders, paresthesias, loss of sensation, weakness, dysarthria, spasticity, ataxia, and bladder dysfunction. The usual pattern is one of recurrent attacks followed by partial recovery (see MULTIPLE SCLEROSIS, RELAPSING-REMITTING), but acute fulminating and chronic progressive forms (see MULTIPLE SCLEROSIS, CHRONIC PROGRESSIVE) also occur.
