TETRASOMY Meaning and
Definition
-
Tetrasomy is a medical term used to describe a genetic disorder characterized by the presence of four copies of a specific chromosome or chromosome segment instead of the typical two copies. This condition results from a chromosomal abnormality known as a "tetrasomic" event, which can occur during the formation of reproductive cells (gametes) or early in embryonic development.
Tetrasomy can affect any chromosome, but the most commonly implicated chromosomes include the sex chromosomes X and Y, as well as chromosomes 13, 18, and 21. The additional genetic material present in tetrasomy individuals can disrupt normal cellular functioning and lead to various physical and developmental abnormalities.
Symptoms and severity of tetrasomy can vary widely depending on the specific chromosome involved and the size of the duplicated segment. Common features associated with tetrasomy include intellectual disabilities, developmental delays, growth abnormalities, distinctive facial features, skeletal malformations, and organ defects. Due to the complex nature of tetrasomy, affected individuals often require multidisciplinary medical care and supportive therapies to address their specific needs.
A diagnosis of tetrasomy is typically made through genetic testing, such as chromosomal analysis or microarray analysis. While tetrasomy is a rare condition, advancements in genetic technology have improved the ability to detect and diagnose this disorder.
In conclusion, tetrasomy is a genetic disorder characterized by the presence of four copies of a specific chromosome or chromosome segment. It can cause a range of physical and developmental abnormalities, requiring specialized care for affected individuals.
