Microdeletion and Microduplication Syndromes in the Human Genome Posted February 21, 2020 Small changes in the sequence of human chromosomes can have detrimental effects in the persons health and development. Summary. The 15q11-q13 microduplication (dup15q11-q13) syndrome is characterized by neurobehavioral disorders, hypotonia, cognitive deficit, language delay and seizures. The format is GTR00000001.1, with a leading prefix 'GTR' followed by 8 digits, a period, then 1 or more digits representing the version. Microdeletion and microduplication syndromes are disorders caused by submicroscopic deletions or duplications of contiguous genes on particular parts of chromosomes. Specialized testing is needed to identify these duplications. 3q29 microduplication syndrome is characterized by widely variable clinical presentation, but generally mild features. In families where the 1q21.1 microduplication has been inherited from a parent, the possibility of having another child-either a girl or a boy-with the 1q21.1 microduplication rises to 50% in each pregnancy. However, the effect of the microduplication on the childs development, health and behaviour cannot be reliably predicted. Chromosomes are made up mostly of DNA and are the structures in the nucleus of the bodys cells that carry genetic information (known as genes), telling the body how to develop, grow and function. 1q21.1 microduplication is a chromosomal change in which a small amount of genetic material on chromosome 1 is abnormally copied (duplicated). The duplication occurs Authors Elham Abbas 1 , Devin M Cox 2 , Teri Smith 1 , Merlin G Butler 2 Affiliations Karyotyping was normal, but subtelomeric analysis revealed a 18q23 duplication. The often affect multiple genes but are too small to be visible with traditional karyotyping methods.

In a common situation a human cell has one pair of identical chromosomes on chromosome 1. Angioedema & Dysmorphic Facies Symptom Checker: Possible causes include Bamforth Syndrome. The 3Mb duplication encompasses a region containing 40 genes including the TBX1 gene that has been shown to be the major disease gene responsible for the DGS/VCFS. The tiny extra bit increases the risk of learning Authors Microduplications are typically one to three megabases (Mb) long and involve several contiguous genes. 15q13.3 microduplication syndrome is caused by having an extra piece of genetic information (duplication) on one of the chromosomes.
