Down syndrome is a genetic disorder, that has an extra chromosome 21, some of it’s characteristics are mild to severe mental impairment, shorter stature, flattened facial profile, and weak muscle tone. Down syndrome is caused when there's an extra copy of chromosome 21. When you have that extra copy means that you have three copies instead of two making it hard to control how much protein is made. Making too much or too little protein can have serious consequences. There are over 50 symptoms of down syndrome, but not everybody with down syndrome has the same features or health problems, Some of the problems and features are common though. Short stature, weak muscles, a short or wide neck, short stocky arms and legs, slanted eyes, nasal bridge that looks pushed in, small ears, irregular and crooked teeth, intellectual disability, heart defects, hypothyroidism, celiac disease, depression. About 1 out of every 660 babies are born with down syndrome. Downs Syndrome is not a dominant, recessive, or sex-linked disorder. Downs Syndrome is not a dominant, recessive, or sex-linked disorder The diagnosis is always based on the presence of an extra number 21 chromosome on a karyotype (a picture of an individual's chromosomes). Because there is no cure, the goals of Down syndrome treatment are to control symptoms and manage any resulting medical conditions. This includes regular checkups and screenings, medications, and surgery. It is rare for people with down syndrome to reproduce. 15% to 30% of women with down syndrome are fertile and they have about a 50% risk of having a child with down syndrome. There's no evidence of a man with down syndrome fathering a child.
