Categories:
Chromosome 10p deletion is a chromosome abnormality that occurs when there is a missing (deleted) copy of genetic material on the short arm (p) of  chromosome 10. The severity and the signs and symptoms depend on the size and location of the deletion and which genes are involved. Features may affect many parts of the body and may include low birth weight, growth delay, developmental delay, low muscle tone (hypotonia), and communication difficulties. Birth defects, various medical problems, and/or distinctive facial features may also be present.[1]

Most 10p deletions are not inherited and occur randomly during the formation of egg or sperm cells, or very early in fetal development. Some 10p deletions are present because a parent has a rearrangement of genetic material on his/her chromosomes. This rearrangement is usually a balanced translocation, which typically does not cause any health problems. In some cases, a parent has the same deletion as the child. Chromosome testing of both parents can provide information about whether the deletion was inherited.[1] Treatment for chromosome 10p deletion is based on the signs and symptoms in each person.

This page is meant to provide general information about 10p deletions. You can contact GARD if you have questions about a specific deletion on chromosome 10p. To learn more about chromosome abnormalities, please visit our GARD webpage on FAQs about Chromosome Disorders.

This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.

Related diseases are conditions that have similar signs and symptoms. A health care provider may consider these conditions in the table below when making a diagnosis. Please note that the table may not include all the possible conditions related to this disease.

Conditions with similar signs and symptoms from Orphanet
The differential diagnosis for patients with distal monosomy 10p should include deletion 22q11 syndrome and other causes of hypoparathyroidism, depending on the phenotype.
Visit the Orphanet disease page for more information.

Support and advocacy groups can help you connect with other patients and families, and they can provide valuable services. Many develop patient-centered information and are the driving force behind research for better treatments and possible cures. They can direct you to research, resources, and services. Many organizations also have experts who serve as medical advisors or provide lists of doctors/clinics. Visit the group’s website or contact them to learn about the services they offer.
