Published by Blackwell V Cormier-Daireq, B Gilbertr, Publishing Ltd, 2013 A Jacquettes,DHerons, P Collignont, D Lacombef, The association of marfanoid habitus (MH) and intellectual disability (ID) F Morice-Picardf, PS Jouku, has been reported in the literature, with overlapping presentations and VCusinv, M Willemsq, genetic heterogeneity. A hundred patients (71 males and 29 females) with w w a MH and ID were recruited.

Eighty patients could be classified as isolated MH and Van Kienaa,CBaumannab, ID: 12 chromosomal imbalances, 1 FBN1 mutation and 1 possibly B Leheupac,DMartin- pathogenic MED12 mutation were found (17%).

These results suggest either that there NMarlea,b, AL Mosca- are more loci with genes yet to be discovered or that MH can also be a Boidrona,b, F Mugnereta, relatively non-specific feature of patients with ID. The search for aortic ah aj complications is mandatory even if MH is associated with ID since FBN1 SGauthier , C Binquet , b,ah mutations or rearrangements were found in some patients.

In ophthalmic, and integumentary systems and the dura 2007, the systematic screening of 737 genes annotated mater. The diagnosis is based on an international in the Vertebrate Genome Annotation database on the classification (1–3). The severity of the condition lies human chromosome X in 250 families with syndromic in the risk of dilation and subsequent dissection of the or non-syndromic X-linked ID led to the identification ascending aorta. The FBN1 gene is the major gene of hemizygous mutations in the MED12 , ZDHHC9 , in patients with MFS, and variable expression of the and UPF3B genes in a very small number of familial disease has been largely identified within and between cases (18–20). The MED12 gene (MIM 300188, also families (4, 5). Patients with atypical presentations not called HOPA or TRAP230 ), located in Xq13, encodes fulfilling the criteria involving only one organ system for a subunit of the macromolecular complex known exist but are rare (6).
