Other Duplications of 15q

Dup15q Alliance provides the following links to help families begin their search for information relevant to their particular diagnosis.​ We do not review or endorse the contents of linked websites.

Microduplications of 15q13.2-13.3

Symptoms of microduplications can vary significantly from those of core 15q duplications. For a description of the genetic differences, please visit our genetics web page. Families affected by 13.2 and 13.3 microduplications have formed a Facebook group and created a website.  Please visit  13.3 Microduplication Parent Facebook Group

Families affected by duplications outside the 15q11.2-13.1 region may find assistance from Unique, an organization based in the United Kingdom, which specializes in support and awareness of rare chromosome disorders, to be helpful. Visit their website at www.rarechromo.org.

Microduplications of 15q11.2

Symptoms of microduplications can vary significantly from those of core 15q duplications. For a description of the genetic differences, please visit our genetics web page. Families affected by 11.2 microduplications have formed a Facebook group and created a website. Please visit www.dup-15q11-2-network.com or 11.2 Microduplication Parent Facebook Group.

Families affected by duplications outside the 15q11.2-13.1 region may find assistance from Unique, an organization based in the United Kingdom, which specializes in support and awareness of rare chromosome disorders, to be helpful. Visit their website at www.rarechromo.org.

Duplications Outside 15q11-13

Families affected by duplications outside the 15q11-13 region may find assistance from Unique, an organization based in the United Kingdom, which specializes in support and awareness of rare chromosome disorders, to be helpful. Visit their website at www.rarechromo.org.

Deletions of Chromosome 15q

Dup15q, Angelman and Prader-Willi syndromes are different disorders, but each is caused by genetic variations within the q11-q13 region of the 15th chromosome. Angelman syndrome and Prader-Willi syndrome are caused by a deletion in this region, while dup15q syndrome is caused by a duplication in the same region. The three disorders share overlapping symptoms and, because of their rarity, are sometimes misdiagnosed for one another.

For more information on the similarities and differences, see our page on International 15q Day or visit Angelman Syndrome Foundation and Prader-Willi Syndrome Association

Microdeletions of 15q13.2-13.3

Families affected by deletions outside the 15q11.2-13.1 region may find assistance from Unique, an organization based in the United Kingdom, which specializes in support and awareness of rare chromosome disorders, to be helpful. Visit their website at www.rarechromo.org. A support group may be found on Facebook, as well. More information on 15q13.2-13.3 microdeletions can be found here.
