Chromosome 6q duplication
Alternate names[edit]
Duplication 6q; Trisomy 6q; 6q duplication; 6q trisomy; Partial trisomy 6q
Definition[edit]
Chromosome 6q duplication is a chromosome abnormality that occurs when there is an extra copy of genetic material on the long arm (q) of chromosome 6.
Cause[edit]
This condition occurs when there is an extra copy of genetic material on the long arm (q) of chromosome 6.
Inheritance[edit]
In most cases, chromosome 6q duplication occurs de novo or is inherited from a parent with a chromosomal rearrangement such as a balanced translocation.
Signs and symptoms[edit]
- The severity of the condition and the signs and symptoms depend on the size and location of the duplication and which genes are involved.
- Features that often occur in people with chromosome 6q duplication include developmental delay, intellectual disability, behavioral problems and distinctive facial features.
Diagnosis[edit]
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[edit]
Treatment is based on the signs and symptoms present in each person.
