Down syndrome or Down's syndrome, also known as trisomy 21, is a genetic disorder caused by the presence of all or part of a third copy of chromosome 21. [3] It is usually associated with developmental delays, mild to moderate intellectual disability, and characteristic physical features. [1] [12] There are three types of Down syndrome, the ...
Chromosome 5q deletion syndrome is an acquired, hematological disorder characterized by loss of part of the long arm ( q arm, band 5q33.1) of human chromosome 5 in bone marrow myelocyte cells. This chromosome abnormality is most commonly associated with the myelodysplastic syndrome . It should not be confused with "partial trisomy 5q", though ...
DiGeorge syndrome, also known as 22q11.2 deletion syndrome, is a syndrome caused by a microdeletion on the long arm of chromosome 22. [7] While the symptoms can vary, they often include congenital heart problems, specific facial features, frequent infections, developmental disability, intellectual disability and cleft palate. [7]
3q29 microdeletion syndrome. 3q29 microdeletion syndrome. Other names. 3qter deletion, Monosomy 3q29. Chromosome 3 is associated with this condition. 3q29 microdeletion syndrome is a rare genetic disorder resulting from the deletion of a segment of chromosome 3. This syndrome was first described in 2005.
Full. Full tetrasomy of an individual occurs due to non-disjunction when the cells are dividing ( meiosis I or II) to form egg and sperm cells ( gametogenesis ). This can result in extra chromosomes in a sperm or egg cell. After fertilization, the resulting fetus has 48 chromosomes instead of the typical 46.
1p36 deletion syndrome is a congenital genetic disorder characterized by moderate to severe intellectual disability, delayed growth, hypotonia, seizures, limited speech ability, malformations, hearing and vision impairment, and distinct facial features. The symptoms may vary, depending on the exact location of the chromosomal deletion.
1q21.1 duplication syndrome or 1q21.1 (recurrent) microduplication is a rare aberration of chromosome 1. [citation needed] On chromosome 1, a human cell typically has one pair of identical chromosomes. One copy of chromosome 1 in the 1q21.1 duplication syndrome is overcomplete because a portion of its sequence has been duplicated twice or more.
