7q11.23 duplication syndrome (also called dup7 or 7dup or duplication of the Williams-Beuren syndrome critical region) is a rare genetic syndrome caused by micro-duplication of 1.5-1.8 mega base in section q11.23 of chromosome 7.
7p22.1 microduplication syndrome (also called Trisomy 7p22.1) is a genetic disorder which is characterized by cranial and facial dysmorphisms, intellectual disability, and motor-speech delays. [1] It is caused by a duplication of the p22.1 region of chromosome 7 .
This category reflects the organization of International Statistical Classification of Diseases and Related Health Problems, 10th Revision. Generally, diseases outlined within the ICD-10 codes Q90-Q99 within Chapter XVII: Congenital malformations, deformations and chromosomal abnormalities should be included in this category.
9q34 deletion syndrome is a rare genetic disorder. Terminal deletions of chromosome 9q34 have been associated with childhood hypotonia, a distinctive facial appearance and developmental disability. The facial features typically described include arched eyebrows, small head circumference, midface hypoplasia, prominent jaw and a pouting lower lip ...
In 10% of the cases, the syndrome is associated with maternal uniparental disomy (UPD) on chromosome 7. [4] This is the result of non-disjunction, where the person receives two copies of chromosome 7 from the mother (maternally inherited) rather than one from each parent.
This is an alphabetically sorted list of all mental disorders in the DSM-IV and DSM-IV-TR, along with their ICD-9-CM codes, where applicable. The DSM-IV-TR is a text revision of the DSM-IV. [ 1 ] While no new disorders were added in this version, 11 subtypes were added and 8 were removed.
The International Statistical Classification of Diseases and Related Health Problems (ICD-10) refers to the diagnosis as "Other dissociative and conversion disorders". [2] Under the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM) , it was known as " Dissociative disorder not otherwise specified " ( DDNOS ).
When the chromosome's structure is altered, this can take several forms: [16] Deletions: A portion of the chromosome is missing or has been deleted. Known disorders in humans include Wolf–Hirschhorn syndrome, which is caused by partial deletion of the short arm of chromosome 4; and Jacobsen syndrome, also called the terminal 11q deletion ...
