The Three Most Common Types Of Down Syndrome

Down Syndrome is caused by a chromosome defect. More specifically, a person with Down Syndrome has an extra copy of chromosome 21. This results in intellectual disabilities, physical abnormalities, developmental delays and other language and non-language characteristics. However, these characteristics do not affect every person with Down Syndrome in the same way. Some may have a mild to moderate intellectual disability, while others may have a more severe intellectual disability. There are three types of Down Syndrome: Trisomy 21, Translocation Down syndrome, and Mosaic Down syndrome. Most of the time, people can’t differentiate between the three without looking at the chromosomes because their physical features and behaviors are similar. Trisomy 21 is the most common type of Down Syndrome, in which each cell has three separate copies of chromosome 21 instead
For example, Down Syndrome can cause heart defects, craniofacial abnormalities, childhood leukemia, or early on-set Alzheimer’s. Developmental delays are one of the main issues concerning Down Syndrome. Milestones, such as crawling, occur almost twice as slow as children without the impairment. The average life-span of a person with this impairment is 55 years of age. Even though people without this impairment look at people with Down Syndrome as disabled, this is not the case at all. There are many examples that show people with Down Syndrome living independent lives, holding jobs, and having relationships, whether that’s in a marital or social context. People are almost always able to recognize a child with Down Syndrome because of their craniofacial abnormalities and poor muscle tone. Children with Down Syndrome are still able to express their feelings and emotions in a full range, being happy when something exciting happens, or being upset if someone hurts their
