Description

Familial and de novo recurrent Xp11.22-p11.23 microduplication has been recently identified in males and females.

SMITH-MAGENIS SYNDROME


Alternate names

SMITH-MAGENIS SYNDROME Is also known as 17p11.2 microdeletion syndrome

Description

Smith-Magenis syndrome (SMS) is a complex genetic disorder characterized by variable intellectual deficit, sleep disturbance, craniofacial and skeletal anomalies, psychiatric disorders, and speech and motor delay.

Most common symptoms of SMITH-MAGENIS SYNDROME

  • Intellectual disability

X-LINKED NON-SYNDROMIC INTELLECTUAL DISABILITY


Alternate names

X-LINKED NON-SYNDROMIC INTELLECTUAL DISABILITY Is also known as mrx, mrx18, mental retardation, x-linked 78, mrx78, mental retardation, x-linked 18

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.

Most common symptoms of X-LINKED NON-SYNDROMIC INTELLECTUAL DISABILITY

  • Intellectual disability
  • Seizures
  • Global developmental delay
  • Generalized hypotonia
  • Microcephaly

AUTISM, SUSCEPTIBILITY TO, X-LINKED 2; AUTSX2


Description

Autism, the prototypic pervasive developmental disorder (PDD), is usually apparent by 3 years of age. It is characterized by a triad of limited or absent verbal communication, a lack of reciprocal social interaction or responsiveness, and restricted, stereotypic, and ritualized patterns of interests and behavior (Bailey et al., 1996; Risch et al., 1999). 'Autism spectrum disorder,' sometimes referred to as ASD, is a broader phenotype encompassing the less severe disorders Asperger syndrome (see ASPG1; {608638}) and pervasive developmental disorder, not otherwise specified (PDD-NOS). 'Broad autism phenotype' includes individuals with some symptoms of autism, but who do not meet the full criteria for autism or other disorders. Mental retardation coexists in approximately two-thirds of individuals with ASD, except for Asperger syndrome, in which mental retardation is conspicuously absent (Jones et al., 2008). Genetic studies in autism often include family members with these less stringent diagnoses (Schellenberg et al., 2006).For a discussion of genetic heterogeneity of autism, see {209850}.

Most common symptoms of AUTISM, SUSCEPTIBILITY TO, X-LINKED 2; AUTSX2

  • Intellectual disability
  • Seizures
  • Delayed speech and language development
  • Atrial septal defect
  • Autism

SEVERE INTELLECTUAL DISABILITY-PROGRESSIVE POSTNATAL MICROCEPHALY-MIDLINE STEREOTYPIC HAND MOVEMENTS SYNDROME


Alternate names

SEVERE INTELLECTUAL DISABILITY-PROGRESSIVE POSTNATAL MICROCEPHALY-MIDLINE STEREOTYPIC HAND MOVEMENTS SYNDROME Is also known as iqsec2-related syndromic intellectual disability

Description

Severe intellectual disability-progressive postnatal microcephaly-midline stereotypic hand movements syndrome is a rare, genetic, syndromic intellectual disability disorder characterized by severe intellectual disability, non-inherited, progressive, post-natal microcephaly, hypotonia, hyperkinesia, absence of speech, strabismus, and midline stereotypic hand movements (e.g. hand washing/rubbing). Additional features include developmental delay, seizures and behavioral disturbances, such as self injury and unexplained crying episodes.
