fi·bril·lin

(fī'bril-in), [MIM*134797]
A microfibrillar protein in connective tissue with a wide distribution in the body; molecular weight about 350,000. There is good evidence that Marfan syndrome is due to mutations of fibrillin.

fibrillin

An extracellular matrix protein, a major component of microfibrils associated with elastin fibres. People with MARFAN'S SYNDROME have abnormal fibrillin as a result of mutations of the FBN1 gene on chromosome 15.
