X-linked Non-syndromic Intellectual Disability

Description

Impaired mental functioning occurs as an isolated feature or as part of many syndromes listed in the X-linked catalog. Mental retardation that is not associated with other distinguishing features is referred to as 'nonspecific.' ClassificationOpitz and Sutherland (1984) reported on a conference in which fragile X mental retardation and X-linked mental retardation of numerous other types were discussed. The report contains a rather comprehensive discussion by Opitz of the nosology of X-linked mental retardation. Mulley et al. (1992) reviewed nomenclature guidelines for X-linked mental retardation.Raymond (2006) reviewed the diagnosis and classification of X-linked mental retardation and discussed the phenotypes associated with genes causing syndromic and nonsyndromic mental retardation.
