Lability, learning disabilities, timidity and social phobia. Mitral valve prolapse with slight reflux and dilatation of the aortic root. Myopia without retinopathy. Karyotype in peripheral blood with G-band, molecular analysis for fragile X and biochemical investigation for homocystinuria had normal results. Patient 2 – female, 19 years, presented clinical symptoms similar to the patient 1 (her brother), although milder. Complementary tests showed no significant changes. Conclusions: These patients present marfanoid aspect and mental retardation consistent with X-linked inheritance. Although no research has been carried out on mutation in the gene MED 12, the clinical diagnosis of Lujan-Fryns syndrome is supported by the literature. There is no specific treatment, and the patients require special education and psychological counseling.
