Weill Marchesani syndrome is a congenital disease that combines microspherophakia and skeletal abnormalities. The authors report a 19-year-old male, born of a consanguineous marriage, with a progressive decrease in visual acuity. The general examination showed a squat look, dwarfism, muscle hypertrophy, short hands and feet, and joint stiffness. The ophthalmological examination showed that visual acuity was limited to hand motion in the right eye despite correction and no perception of light in the left eye. Intraocular pressure was 36 mmHg in the right eye and 40 mmHg in the left eye. The anterior chamber was irregular with iridophakodonesis and microspherophakia of both lenses. The zonula was partially ruptured in the right eye. The iridocorneal angle was narrow. Fundus eye examination showed a pale optic disc with an excavation of 9/10 on the right. In the left eye, the optic disc was totally excavated. Cardiovascular check-up revealed rheumatic aortic valvular cardiopathy. The therapy consisted of combined surgery: phakophagia with anterior vitrectomy plus trabeculectomy operated on the right eye. Weill Marchesani syndrome is a rare congenital affection with a recessive autosomal transmission. The visual prognosis is dominated by secondary glaucoma due to pupillary blockage by the mobile eye lens. This observation illustrates the seriousness of spontaneous progression in Weill Marchesani syndrome, justifying the necessity of lens extraction before the onset of complications.

The acromelic dysplasia group includes three rare disorders: Weill-Marchesani syndrome (WMS), Geleophysic dysplasia (GD) and Acromicric dysplasia (AD) all characterized by short stature, short hands and stiff joints. The clinical overlap between the three disorders is striking. Indeed, in addition to the diagnostic criteria, they all share common features including delayed bone age, cone shaped epiphyses, thick skin and heart disease. In contrast, a microspherophakic lens seems to be a characteristic feature of WMS whereas hepatomegaly and a severe outcome are encountered only in the most severe forms of GD. Finally, WMS is transmitted either by an autosomal dominant or an autosomal recessive (AR) mode of inheritance, GD by an autosomal recessive mode of inheritance and AD by an autosomal dominant mode of inheritance. Using genetic approaches, we have identified the molecular basis of WMS and GD which both involved the same superfamily of proteins, the ADAMTS [A Disintegrin-like And Metalloproteinase domain (reprolysin type) with ThromboSpondin type 1 repeats (TSR)]. We have found ADAMTS10 mutations in the recessive form of WMS and Fibrillin 1 mutations in the dominant form of WMS. More recently, we have identified ADAMTSL2 mutations in GD. The function of ADAMTS1 0 and AD AMTSL 2 are unknown. But the findings of FBN1 and ADAMTS10 mutations in WMS suggest a direct link between the two proteins. Using a yeast double hybrid screen, we have identified LTBP1 (Latent TGFbeta Binding protein 1) as a partner of ADAMTSL2. The combination of these findings suggests that ADAMTS10 and ADAMTSL2 are both involved in the microfibrillar network.
