    Gene linked to mental retardation and cognitive function: By Sarah Post. August 2, gene known as AGTR2, which has been shown in mice to play a role in the central nervous system, has now been associated with mental retardation in human patients.. Researchers have found that diminished mental capacity appears to be correlated with mutations in the gene or physical changes in its. The historical record reveals the various meanings associated with mental retardation and its analogous conditions, including idiocy, foolishness, feeblemindedness, and mental deficiency. A review of this history depicts the many ways that mental retardation has been and continues to be defined.

the new mutation rate, for autosomal dominant forms. Where the phenotype is common i.e. mental retardation without syn-dromic features, the identification of these individuals is clini-cally difficult and thus the number of characterized autosomal dominant genes that give rise to mental retardation is low.

The human species has a tremendous potential for adaptation, a potential accompanied by the promise of great diversity across its individuals.

Human development, from the moment of conception, is influenced by a multitude of factors including genetic heritage, interaction with the physical and social environment, and personal biological and Cited by: 1. There are many causes of mental retardation, including genetic and chromosomal disorders, infections during pregnancy, drug and alcohol use during pregnancy, problems with the birth or delivery, prematurity and low family IQ in general.

Despite advances in medical diagnosis, the cause of MR in many individuals is unknown. Individuals affected by mental retardation are a clinically and aetiologically heterogeneous group.

This heterogeneity is particularly highlighted when we consider the genetics of mental retardation. Retardation in which there is no biological defect such as down syndrome, is called _____ cultural retardation if there is a family history of mental retardation.

Familial __________is the degree to which genetics play a role determining characteristics such as intelligence. DIAGNOSTIC EVALUATION OF THE MENTALLY RETARDED While genetically related disorders are responsible for nearly 50 percent of moderate mental retardation, an accurate diagnosis is essential for possible treatment and prevention by genetic coun seling and prenatal diagnosis.

Classification of Mental Retardation However, the AAMR has introduced a new system of classification that is based on the amount of support that the person needs in order to function to the highest possible level The four categories of mental retardation according to the intensity of needed supports are: (Wehmeyer, ).

This clinical report describes the clinical genetic evaluation of the child with developmental delays or mental retardation.

Genetic studies of children with mental retardation SaidehRajaei Department of Medical and Clinical Genetics, Institute of Biomedicine The Sahlgrenska Academy at the University of Gothenburg, Gothenburg, Sweden, Mental retardation (MR) is characterised by significant limitations in intellectual function and adaptive behaviour.

Severe and profound mental retardation are usually caused by genetic mutations or accidents during birth, whereas mild forms have both genetic and environmental influences. One cause of mental retardation is Down syndrome, a chromosomal disorder leading to mental retardation caused by the presence of all or part of an extra 21st chromosome.

Mental retardation is a developmental disability that first appears in children under the age of It is defined as an intellectual functioning level (as measured by standard tests for intelligence quotient) that is well below average and significant limitations in daily living skills (adaptive functioning).

Description. Genetic mental retardation refers to a deficiency of mental capacity that is at the mercy of a genetic predisposition. Like many other conditions, mental retardation and other mental problems can be brought about for many reasons. Sometimes, substance abuse or trauma can cause conditions like this; other times, it may be inherited.

The term mental retardation should be cast aside because it is stigmatizing, and genetic causes. Mild intellectual disability is 4 times more likely to be found in the offspring of women who As a result, new cases of mild intellectual disability continue to be diagnosed among children up to File Size: KB.

The Diagnostic and Statistical Manual of Mental Disorders (DSM) (latest edition: the DSM-5, published in ) is a publication for the classification of mental disorders using a common language and standard criteria.

It is published by the American Psychiatric Association (APA) and is used by clinicians, researchers, psychiatric drug regulation agencies, health insurance companies. Researchers have discovered several new genetic causes of mental retardation. One form of retardation, caused by a large deletion that spans six genes on chromos has characteristic facial.

Genetics of mental retardation This, in fact, is one of the complex neuropsychiatric disorders for which the etiopathogenesis is still poorly understood. This condition, of great concern for public health and society, is estimated to occur in 1% to 10% of the population, and research on its etiology has always been a challenge in medicine.

Developmental disability is a diverse group of chronic conditions that are due to mental or physical impairments that arise before adulthood. Developmental disabilities cause individuals living with them many difficulties in certain areas of life, especially in "language, mobility, learning, self-help, and independent living".

Developmental disabilities can be detected early on and persist Specialty: Psychiatry. Brachydactyly type D, also known as short thumb or stub thumb and commonly referred to as clubbed thumb, is a condition clinically recognised by a thumb being relatively short and round with an accompanying wide nail bed.

The distal phalanx of affected thumbs is approximately two-thirds the length of full-length thumbs. It is a type of brachydactyly, or shortness of digits, and is associated Specialty: Medical genetics.

The Severity of Genetic Disorders and the Degree of Impairment. Genetic disorders differ greatly in the impairment they entail. For example, Lesch-Nyhan syndrome involves severe mental retardation and self-mutilation (viz., biting fingers, lips, and shoulders) necessitating restraints on the child.
