Summary
This study details three patients with distal 22q duplication (dup(22q)) syndrome. Their varied clinical presentations highlight the syndrome
Area of Science:
- Genetics
- Human Molecular Genetics
- Clinical Genetics
Background:
- Duplication of distal 22q is a rare chromosomal abnormality.
- Understanding the genetic basis and phenotypic spectrum of dup(22q) is crucial.
Observation:
- Three patients with distal 22q duplication were analyzed.
- One patient had a de novo translocation t(21;22)(p13;q11).
- Two patients were offspring of a translocation carrier t(10;22)(q26;q12).
Findings:
- The patients presented with variable clinical manifestations.
- This variability underscores the complex nature of the dup(22q) syndrome.
- Genetic origin (de novo vs. inherited translocation) may influence phenotype.
Implications:
- These cases expand the known clinical spectrum of dup(22q) syndrome.
- Further research is needed to correlate specific genetic alterations with clinical outcomes.
- Improved understanding can aid in genetic counseling and patient management.
