Summary
This study reports a rare duplication of the 10q22.1-q25.1 chromosomal segment in a 12-year-old girl. This case highlights the genetic basis of intellectual disability and distinctive facial features associated with this specific chromosomal abnormality.
Area of Science:
- Genetics
- Human Biology
- Medical Science
Background:
- Chromosomal duplications can lead to developmental abnormalities.
- The 10q22.1-q25.1 segment is rarely reported with duplications.
- Previous cases of 10q22.1-q25.1 duplication were documented in fetal cases.
Observation:
- A 12-year-old girl presented with intellectual disability.
- The patient exhibited distinctive facial dysmorphology.
- This is the second reported case of duplication for the 10q22.1-q25.1 segment.
Findings:
- The case confirms the association between 10q22.1-q25.1 duplication and intellectual disability.
- Distinctive facial dysmorphology is a key phenotypic feature of this duplication.
- This pediatric case provides further evidence for the clinical significance of this chromosomal segment.
Implications:
- Understanding chromosomal abnormalities like 10q22.1-q25.1 duplication is crucial for genetic counseling.
- Further research into this specific duplication can improve diagnostic accuracy.
- This case contributes to the literature on rare genetic disorders affecting development.
