title: [Chromosome X-linked mental retardation and marfanoid syndrome].
abstract: In the present paper we report two pairs of slightly to moderately mentally retarded brothers with Marfanoid habitus and similar craniofacial changes. They had a long and narrow face, small mandible, high-arched palate and hypernasal voice, as previously reported by Lujan et al. (1984) in 4 mentally retarded males of a large kindred. The present data suggest the existence of a specific type of X-linked mental retardation with Marfanoid habitus.
