WebMarfan syndrome is caused by mutations in a gene called FBN1, or fibrillin 1, on chromosome 15. It’s autosomal dominant, which means that even if there’s a normal copy of the gene, a single mutated copy of the gene – in other words a heterozygous mutation – is sufficient to cause the disease. WebMarfan syndrome is a genetic disorder that affects the connective tissue and is caused by a mutation in the fibrillin-1 (FBN1) gene on chromosome 15. The FBN1 gene encodes an FBN1 protein which is a principal component of the zonules, and its defect results in ectopia lentis (50%–80% cases).[ 1 , 2 ] Marfan syndrome is a systemic disease that classically …
