Isodicentric 15
Isodicentric 15
Isodicentric 15 (pronounced: iso-di-centric fif-teen), also known as idic(15) or partial tetrasomy 15q, is a chromosomal abnormality in which a child is born with extra genetic material from chromosome 15. This condition is a type of chromosomal duplication.
Etymology
The term "isodicentric" is derived from the Greek words "iso" meaning equal, and "di" meaning two, and "centric" referring to the centromere, the part of a chromosome that links sister chromatids. The number "15" refers to the specific chromosome that is duplicated in this condition.
Symptoms
Children with isodicentric 15 may have developmental delays, intellectual disability, and behavioral problems. They may also have physical abnormalities such as unusual facial features, seizures, and low muscle tone (hypotonia). However, the severity of these symptoms can vary widely among affected individuals.
Diagnosis
Isodicentric 15 is diagnosed through a genetic test called a chromosome analysis or karyotype. This test can identify the extra chromosome 15 material in a person's cells.
Treatment
There is no cure for isodicentric 15, but treatments can help manage the symptoms. These may include physical, occupational, and speech therapy, as well as medications to control seizures and behavioral problems.
