Insights
This case study details a rare deletion on chromosome 12p (12p13.1-13.3) in an infant. This genetic finding is associated with mild intellectual disability and unilateral ectrodactyly.
Area of Science:
- Genetics
- Developmental Biology
- Clinical Medicine
Background:
- Genetic deletions can lead to significant developmental abnormalities.
- The 12p13.1-13.3 region is implicated in neurodevelopmental processes.
Observation:
- A case report of a rare deletion in the 12p13.1-13.3 chromosomal region.
- The affected infant presented with mild intellectual disability.
- Unilateral ectrodactyly was a notable clinical feature.
Findings:
- This specific deletion (12p13.1-13.3) is exceedingly rare, with only one prior documented case.
- The findings suggest a potential link between this 12p deletion and the observed neurodevelopmental and limb malformation phenotypes.
Implications:
- Further research is warranted to understand the precise genes and mechanisms affected by this deletion.
- This case contributes to the limited literature on 12p deletions and their clinical manifestations.
- Highlights the importance of detailed genetic analysis in cases of unexplained intellectual disability and congenital anomalies.
Abstract:
The authors report a case of a deletion at 12p13.1-13.3. Only one similar observation was published [16]. The infant is mildly retarded and shows unilateral ectrodactyly.
