Chromosomal deletion syndrome

Chromosomal deletion syndrome is a group of disorders characterized by the loss of genetic material from one of the 46 human chromosomes. These syndromes can lead to a variety of physical, mental, and developmental problems.

Causes

Chromosomal deletion syndromes are caused by the loss of genetic material from one of the 46 human chromosomes. This can occur during the formation of reproductive cells (eggs and sperm) or in early fetal development. The severity of the syndrome depends on the size and location of the deletion.

Symptoms

The symptoms of chromosomal deletion syndromes can vary widely, depending on the specific syndrome and the size and location of the deletion. Common symptoms can include growth delays, intellectual disability, physical abnormalities, and health problems.

Diagnosis

Diagnosis of chromosomal deletion syndromes typically involves genetic testing. This can include karyotyping, which is a test that examines the size, shape, and number of chromosomes, and microarray analysis, which can detect small deletions that may not be visible on a karyotype.

Treatment

There is no cure for chromosomal deletion syndromes, but treatment can help manage symptoms. This can include physical therapy, occupational therapy, speech therapy, and educational support. Some individuals may also require medical treatment for health problems associated with the syndrome.
