Abstract
Background Schnyder's crystalline corneal dystrophy (SCCD) is a rare autosomal dominant disease and can occur in association with hyperlipoproteinemia. The disease has been mapped to chromosome 1p34.1–p36. Case report We report on a 66-year-old woman and her son with Schnyder's crystalline corneal dystrophy. The mother had type IV hyperlipoproteinemia and hypercholesterolemia while her son had hypercholesterolemia with elevated LDL-cholesterol. Analysis of microsatellite markers within the candidate interval of 1p34.1–p36 showed that the affected son and his unaffected brother had inherited different alleles only for the proximal marker D1S228 from their affected mother. Conclusions The haplotype analysis suggests that either recombination has occurred, which would allow the candidate interval to be narrowed down, or alternatively, the SCCD in the reported family is not linked to chromosome 1, which would be a first indication of genetic heterogeneity in this disease. To reduce the risk of cardiovascular disease, hyperlipidemia should always be excluded in patients with Schnyder's crystalline corneal dystrophy.
