Autism

Autism is a neurodevelopmental disorder characterized by impaired social interaction and communication, and by restricted and repetitive behavior. Autism begins in childhood. It is marked by the presence of markedly abnormal or impaired development in social interaction and communication and a markedly restricted repertoire of activity and interest. Manifestations of the disorder vary greatly depending on the developmental level and chronological age of the individual (DSM-IV). [from HPO]

Autistic disorder of childhood onset

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). Levy et al. (2009) provided a general review of autism and autism spectrum disorder, including epidemiology, characteristics of the disorder, diagnosis, neurobiologic hypotheses for the etiology, genetics, and treatment options. Genetic Heterogeneity of Autism Autism is considered to be a complex multifactorial disorder involving many genes. Accordingly, several loci have been identified, some or all of which may contribute to the phenotype. Included in this entry is AUTS1, which has been mapped to chromosome 7q22. Other susceptibility loci include AUTS3 (608049), which maps to chromosome 13q14; AUTS4 (608636), which maps to chromosome 15q11; AUTS5 (606053), which maps to chromosome 2q; AUTS6 (609378), which maps to chromosome 17q11; AUTS7 (610676), which maps to chromosome 17q21; AUTS8 (607373), which maps to chromosome 3q25-q27; AUTS9 (611015), which maps to chromosome 7q31; AUTS10 (611016), which maps to chromosome 7q36; AUTS11 (610836), which maps to chromosome 1q41; AUTS12 (610838), which maps to chromosome 21p13-q11; AUTS13 (610908), which maps to chromosome 12q14; AUTS14A (611913), which has been found in patients with a deletion of a region of 16p11.2; AUTS14B (614671), which has been found in patients with a duplication of a region of 16p11.2; AUTS15 (612100), associated with mutation in the CNTNAP2 gene (604569) on chromosome 7q35-q36; AUTS16 (613410), associated with mutation in the SLC9A9 gene (608396) on chromosome 3q24; AUTS17 (613436), associated with mutation in the SHANK2 gene (603290) on chromosome 11q13; and AUTS18 (615032), associated with mutation in the CHD8 gene (610528). (NOTE: the symbol 'AUTS2' has been used to refer to a gene on chromosome 7q11 (KIAA0442; 607270) and therefore is not used as a part of this autism locus series.) There are several X-linked forms of autism susceptibility: AUTSX1 (300425), associated with mutations in the NLGN3 gene (300336); AUTSX2 (300495), associated with mutations in NLGN4 (300427); AUTSX3 (300496), associated with mutations in MECP2 (300005); AUTSX4 (300830), associated with variation in the region on chromosome Xp22.11 containing the PTCHD1 gene (300828); AUTSX5 (300847), associated with mutations in the RPL10 gene (312173); and AUTSX6 (300872), associated with mutation in the TMLHE gene (300777). Folstein and Rosen-Sheidley (2001) reviewed the genetics of autism. [from OMIM]

SUPERNUMERARY DER(22)t(8

Carriers of the balanced constitutional translocation t(8;22)(q24.13;q11.2) are phenotypically normal but are at risk of having progeny with supernumerary der(22)t(8;22) syndrome as a result of malsegregation of the der(22). Although the supernumerary der(22)t(8;22) phenotype is variable between individuals, it tends to include ear and extremity abnormalities in addition to mild mental retardation (summary by Sheridan et al., 2010). [from OMIM]

Mental disorder

Mental disorders include a wide range of problems, including. -Anxiety disorders, including panic disorder, obsessive-compulsive disorder, post-traumatic stress disorder, and phobias. -Bipolar disorder. -Depression. -Mood disorders. -Personality disorders. -Psychotic disorders, including schizophrenia. There are many causes of mental disorders. Your genes and family history may play a role. Your life experiences, such as stress or a history of abuse, may also matter. Biological factors can also be part of the cause. A traumatic brain injury can lead to a mental disorder. A mother's exposure to viruses or toxic chemicals while pregnant may play a part. Other factors may increase your risk, such as use of illegal drugs or having a serious medical condition like cancer. Medications and counseling can help many mental disorders. .  [from MedlinePlus]

Asperger disorder

Asperger syndrome is a disorder on the autism spectrum, which is a group of conditions characterized by impaired communication and social interaction. Asperger syndrome is on the mild, or "high-functioning," end of the autism spectrum. Many affected individuals learn to compensate for their differences and live independent and successful lives. However, the behavioral challenges associated with this condition often lead to social isolation and difficulties at school, at work, and in personal relationships.People with Asperger syndrome have average or above-average intelligence. In contrast to people with other disorders on the autism spectrum, they are not delayed in their language development. However, their ability to carry on a conversation is often impaired by a tendency to take idioms or humorous statements literally and an inability to read non-verbal cues such as body language to understand what others are feeling. They may speak in a monotone voice, have unusual mannerisms, or choose unusual topics of conversation.Individuals with Asperger syndrome tend to develop an intense interest in a particular subject. This interest may be a traditional hobby or academic discipline, and many people with Asperger syndrome develop advanced abilities in fields such as music, science, mathematics, or computer programming. However, they might also focus on an unusual interest such as bus routes or a particular type of household appliance. Often they are able to remember enormous amounts of detail on their subject of interest. They may want to share this large amount of information with others and may resist diversion to other topics.People with Asperger syndrome tend to be rigid about their established routines and may strongly resist disruptions such as changes in schedule. They may also have difficulty tolerating sensory stimuli such as noise or lights.Other features of Asperger syndrome may include mild impairment of motor skills. For example, basic skills such as crawling and walking may be somewhat delayed. Affected individuals may also have coordination problems that impair their ability to engage in such activities as playing ball games or riding a bicycle. This physical clumsiness may lead to further social isolation of children with Asperger syndrome.Signs and symptoms of Asperger syndrome may become apparent by the age of 3, when most children begin to develop social skills such as learning to play with others. Some affected children may come to medical attention due to delayed motor skills. In most cases, children with Asperger syndrome are diagnosed during the elementary school years, as their social behavior continues to diverge from the typical developmental path. Difficulties with social skills generally continue into adulthood, and affected individuals are at increased risk of other behavioral or psychiatric disorders such as attention deficit-hyperactivity disorder (ADHD), depression, anxiety, and obsessive-compulsive disorder.

Asperger syndrome 4

Asperger syndrome is considered to be a form of childhood autism (see, e.g., 209850). The DSM-IV (American Psychiatric Association, 1994) specifies several diagnostic criteria for Asperger syndrome, which has many of the same features as autism. In general, patients with Asperger syndrome and autism exhibit qualitative impairment in social interaction, as manifest by impairment in the use of nonverbal behaviors such as eye-to-eye gaze, facial expression, body postures, and gestures, failure to develop appropriate peer relationships, and lack of social sharing or reciprocity. Patients also exhibit restricted, repetitive and stereotyped patterns of behavior, interests, and activities, including abnormal preoccupation with certain activities and inflexible adherence to routines or rituals. Asperger syndrome is primarily distinguished from autism by the higher cognitive abilities and a more normal and timely development of language and communicative phrases. Gillberg et al. (2001) described the development of the Asperger syndrome (and high-functioning autism) Diagnostic Interview (ASDI), which they claimed has a strong validity in the diagnosis of the disorder. For a discussion of genetic heterogeneity of Asperger syndrome, see ASPG1 (608638). [from OMIM]

Other autosomal loci include ASPG2 (608631) on chromosome 17p, ASPG3 (608781) on 1q21-q22, and ASPG4 (609954) on 3p24-p21. Two X-linked forms, ASPGX1 (300494) and ASPGX2 (300497), are associated with mutation in the NLGN3 gene (300336) and the NLGN4 gene (300427), respectively. [from OMIM]
