Chromosome 7p deletion

Alternate names

Deletion 7p; Monosomy 7p; 7p deletion; 7p monosomy; Partial monosomy 7p

Definition

Chromosome 7p deletion is a chromosome abnormality that occurs when there is a missing copy of the genetic material located on the short arm (p) of chromosome 7.

Cause

This condition occurs when there is a missing copy of the genetic material located on the short arm (p) of chromosome 7.

Inheritance

Most cases are not inherited, but people can pass the deletion on to their children.

Signs and symptoms

• The severity of the condition and the signs and symptoms depend on the size and location of the deletion and which genes are involved.
• Features that often occur in people with chromosome 7p deletion include developmental delay, intellectual disability, behavioral problems, and distinctive facial features.

Diagnosis

Chromosome disorders may be suspected in people who have developmental delays, intellectual disabilities and/or physical abnormalities.

Several types of genetic tests can identify chromosome disorders:

• Karyotyping
• Microarray (also called array CGH)
• Fluorescence in situ hybridization (FISH)

Treatment

Treatment is based on the signs and symptoms present in each person.
