What may cause Marfan syndrome?
Some diseases are also associated with features that resemble Marfan syndrome. For example, multiple endocrine neoplasia (MEN) type III is associated with what’s been called a marfanoid habitus — patients commonly have the elongated axial bones and hyperextensible joints seen in true Marfan syndrome. MEN-III is caused by a mutation in the RET gene on chromosome 10. It is inherited in an autosomal dominant pattern.
