SCIENTIFIC BACKGROUND

ADAMTS10, ADAMTS17, FBN1, LTBP2

Weill-Marchesani syndrome (WMS) is a rare connective tissue disease characterized by characteristic ocular symptoms: microspherophakia, severe myopia, lens ectopia and glaucoma. Other symptoms include proportionate short stature, brachydactyly, joint stiffness and cardiac anomalies such as pulmonary valve stenosis, mitral regurgitation or aortic valve stenosis.

 

WMS can be inherited in an autosomal dominant or autosomal recessive pattern, with no clinical difference between the two forms. In the majority of patients, the recessive form is present with homozygous or combined heterozygous variants in the ADAMTS10 gene (WMS1), which codes for a metalloproteinase of the extracellular matrix. Variants in the LTBP2 gene have occasionally been described in the second recessively inherited form (WMS3). A third, rare, recessively inherited form (WMS4) is caused by homozygous variants in the ADAMTS17 gene. Heterozygous variants in the FBN1 gene are the cause of the dominantly inherited form (WMS2), although it has only been described in a few families.
