MARFAN syndrome is an inherited disorder of connective tissue
manifested in the ocular, skeletal and cardiovascular systems. It is
inherited as an autosomal dominant with high penetrance, but has great
clinical variability1. Linkage studies have mapped the Marfan
locus to chromosome 15q 15–21.3 (refs 2, 3). There have been no reports
of genetic heterogeneity in the syndrome. Following the identification of fibrillin (a glycoprotein component of the extracellular
microfibril4), immunohistopathological quantification of the protein in skin and fibroblast culture5, and examination of fibrillin synthesis, extracellular transport, and incorporation into the
extracellular matrix (D. M. Milewicz, R.E.P., E. S. Crawford and P. H. Byers,
manuscript in preparation) have demonstrated abnormalities of fibrillin
metabolism in most patients. A portion of the complementary DNA encoding
fibrillin has been cloned6 and mapped by in
situ hybridization to chromosome 15 (ref. 7). Here we report that the
fibrillin gene is linked to the Marfan phenotype ( =0.00; logarithm of
the odds (lod) = 3.9) and describe a de novo missense mutation in the
fibrillin gene in two patients with sporadic disease. We thus implicate
fibrillin as the protein defective in patients with the Marfan syndrome.
