Two siblings had identical clinical features, with late childhood onset of symptoms and slow progression, requiring crutches to walk at ages 37 and 38 years. Another patient developed ataxia aged 13 years and became wheel chair bound by 20 years of age. Although they all had raised serum AFP levels, their clinical, immunological, biochemical, cytogenetic and molecular genetic studies failed to support a diagnosis ofAtaxia Telangiectasia. Extensive investigation including imaging, biochemical and genetic studies excluded other known ataxias. Their clinical features most closely resemble the phenotype of a single consanguineous Japanese family with four individuals affected by spinocerebellar ataxia, peripheral neuropathy, raised AFP and hypercholesterolaemia. Homozygosity mapping has identified a locus in this Japanese family at 9q34. Haplotype analysis of our cases demonstrated possible linkage to 9q34, suggesting these may be the first Caucasian families described with this disorder.展开更多
