(Noun. /SIN-drom)
by Yasemin Cole
What does it mean?
This word is used to describe a set of symptoms that typically co-occur in diseases. Usually, a medical condition is not solely a single symptom but a set of symptoms an individual experiences. The larger this set of symptoms is, the greater the likelihood of the individual having this condition. For example, you may have heard of Down syndrome. This genetic condition results from an extra copy of chromosome 21 and, therefore, an “extra set” of genes in each cell. This additional genetic material results in a number of manifestations, including characteristic facial features, muscle weakness, decreased height, and intellectual disability. It’s important to note that each person experiences these symptoms differently: Some are mildly affected, while others are more severely affected.
How do I use it in a sentence?
“A new patient had an appointment with a geneticist to learn whether they had a genetic syndrome.”
