| A newly described variant of Ehlers-Danlos syndrome (EDS). Affected patients exhibit features consistent with EDS, including joint hypermobility, skin fragility and aortic dilatation. They also have periventricular heterotopia, which has characteristics of focal epilepsy usually beginning in the second decade of life. Intelligence is generally normal. Some patients also have cardiac anomalies such as patent ductus arteriosus, bicuspid aortic valves, or aneurysmal dilatation of the sinus of Valsalva. Caused by mutations in the filamin A gene (FLNA) located at locus Xq28 on the long arm of chromosome X. This suggests a novel cause of EDS. The disease is transmitted as an X-linked dominant trait. |
