Marfan Lipodystrophy Syndrome

Clinical Characteristics
Ocular Features: 

The eyes are large resulting in high myopia and apparent proptosis.  The palpebral fissures usually slant downwards and ectopia lentis may be present.  

Systemic Features: 

This syndrome shares many features of Marfan syndrome (154700) such as tall stature, dislocated lenses, myopia, high arched palate, aortic root and valvular anomalies, arachnodactyly, high arched palate, lax and hyperextensible joints, and pectus excavatum.  In addition, MFLS patients have retrognathia, intrauterine growth retardation, scarce or absent subcutaneous fat, a progeroid facies, and sometimes macrocephaly.  Postnatal growth and psychomotor development have been reported to be normal albeit with slow weight gain.


This condition is transmitted as an autosomal dominant as the result of heterozygous mutations in FBN1 (15q21.1).  The same gene is mutated in 6 other conditions in this database including Marfan Syndrome (154700) with which it shares some features.

Treatment Options: 

There is no treatment for the overall condition but individual features such as ectopia lentis can be surgically corrected.  Patients with high myopia require frequent evaluation for retinal tears and detachments.  Cardiac monitoring likewise is important to monitor for aortic valve prolapse and dilation of the aortic root.
