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 21 (Spanish: Cromosoma 21) is a Chilean crime thriller television series co-created by Matías Venables and Nico Martínez Bergen. The series traces a police investigation into a young man with down syndrome involved in a murder. It had its original run on Chilean network Canal 13 on 14 October 2022.
Down syndrome is a chromosomal abnormality characterized by the presence of an extra copy of genetic material on chromosome 21, either in whole (trisomy 21) or part (such as due to translocations). The effects of the extra copy varies greatly from individual to individual, depending on the extent of the extra copy, genetic background ...
Most people have two copies of chromosome 21, while those with three copies of chromosome 21 (trisomy 21) have Down syndrome . Researchers working on the Human Genome Project announced in May 2000 that they had determined the sequence of base pairs that make up this chromosome. [5]
Erik Barmack’s Wild Sheep Content, the new L.A.-based company of the former Netflix VP, has boarded “Cromosoma 21,” an original crime mystery series created and directed by Chile’s Matías ...
Down syndrome research. Chromosome 21 from Human Genome Program. Research of Down syndrome-related genes is based on studying the genes located on chromosome 21. In general, this leads to an overexpression of the genes. [1] [2] Understanding the genes involved may help to target medical treatment to individuals with Down syndrome.
XX male syndrome, also known as de la Chapelle syndrome, is a rare condition in which an individual with a 46,XX karyotype develops a male phenotype. Synonyms for XX male syndrome include 46,XX testicular difference of sex development (or 46,XX DSD)
This is a list of people with Down syndrome, a condition also known as Down's syndrome or trisomy 21. Down syndrome is a genetic disorder caused by the presence of all or part of a third copy of chromosome 21. It is typically associated with developmental delays, characteristic physical features, and mild to moderate intellectual disability.
World Down Syndrome Day ( WDSD) is marked each year on March 21, [1] beginning in 2007. The 21st day of March (the 3rd month of the year) was selected to signify the uniqueness of the triplication ( trisomy) of the 21st chromosome which causes Down syndrome.
Monosomy 9p (also known as Alfi's Syndrome or simply 9P-) is a rare chromosomal disorder in which some DNA is missing or has been deleted on the short arm region, "p", of one copy of chromosome 9 (9p22.2-p23). [1] [2] This deletion either happens de novo or as a result of a parent having the chromosome abnormality. [3]
