Additional Information:

Description: (OMIM) The term 'X-linked mental retardation-hypotonic facies syndrome' comprises several syndromes previously reported separately. These include Juberg-Marsidi, Carpenter-Waziri, Holmes-Gang, and Smith-Fineman-Myers syndromes as well as 1 family with X-linked mental retardation with spastic paraplegia. All these syndromes were found ...
Clinical Description OMIM Smith et al. (1980) described 2 brothers with a combination of mental retardation, microcephaly, short stature, and unusual facial appearance, including slanted palpebral fissures, narrow face with maxillary overjet, alternating exotropia, and ptosis. Muscle tone was hypotonic, but ...
Molecular genetics OMIM In 1 surviving affected member and many heterozygous carriers of a family previously reported by Mattei et al. (1983) as having Juberg-Marsidi syndrome, Villard et al. (1996) identified a mutation in the ATRX gene (300032.0011).
