Introduction to X-linked mental retardation De silva type
The phenotype represented in this entry is termed X-linked syndromic mental retardation, Turner type because the first mutation in the HUWE1 gene was found in the large affected family originally reported by Turner et al. (1994).Subsequently, HUWE1 mutations were found in patients with several other similar X-linked disorders, including Juberg-Marsidi syndrome and Brooks-Wisniewski-Brown.
X linked mental retardation (XLMR) is subdivided in two categories⁚ syndromic XLMR (MRXS) when MR is associated with clinical features and non-syndromic XLMR (MRX) when MR is isolated. Aim⁚ The aim of this systematic review of the literature was to join together the results of several studies related to X linked mental retardation and to.
Billuart et al. (1998) reported a large family in which 4 males had X-linked mental retardation. Des Portes et al. (2004) performed clinical and 3-dimensional brain MRI evaluations on the affected males of the family studied by Billuart et al. (1998) and an unrelated female patient with an X;12 balanced translocation described by Bienvenu et al. (1997) (see 300127).
The fragile X syndrome is the second most common chromosome abnormality, after trisomy 21 or Downs syndrome, among the mentally retarded. While trisomy 21 is usually sporadic, the fragile X syndrome is transmissible and is the most common genetic cause of mental retardation. The first report of a marker X chromosome containing a.
Introduction. Mutations resulting in X-linked intellectual disability (XLID) have been described in 102 genes (Table S1, available online). 1 This work was accomplished over a 40 year period during which the term X-linked mental retardation was widely used; however, we will use intellectual disability (ID), which is emerging as the preferred terminology.
