Summaries for Chromosome 15q11.2 Deletion Syndrome

NIH Rare Diseases : 53 15q11.2 microdeletion refers to a chromosome abnormality in which a tiny piece of genetic material on the long arm of chromosome 15 (at a location designated q11.2) is missing (deleted). The features of people with a 15q11.2 microdeletion vary widely. The most common features include developmental, motor, and language delays; behavior and emotional problems; attention deficit disorders; and autism spectrum disorder. Other features may include birth defects and seizures. However, some people have no apparent physical, learning, or behavior problems. A 15q11.2 microdeletion may occur randomly for the first time in an affected person, or it may be inherited from a parent. Treatment depends on the signs and symptoms in each person.

MalaCards based summary : Chromosome 15q11.2 Deletion Syndrome, also known as 15q11.2 microdeletion syndrome, is related to chromosome 15q11-q13 duplication syndrome and alkuraya-kucinskas syndrome, and has symptoms including seizures, ataxia and clumsiness. An important gene associated with Chromosome 15q11.2 Deletion Syndrome is DEL15Q11.2 (Chromosome 15q11.2 Deletion Syndrome). Affiliated tissues include heart, and related phenotypes are hypertelorism and intellectual disability

OMIM : 57 A heterozygous deletion of chromosome 15q11.2 may increase the susceptibility to neuropsychiatric or neurodevelopmental problems, including delayed psychomotor development, speech delay, autism spectrum disorder, attention deficit-hyperactivity disorder, obsessive-compulsive disorder, and possibly seizures (summary by Doornbos et al., 2009 and Burnside et al., 2011). See also chromosome 15q11.2 duplication syndrome (608636). (615656)
