[Monosomy 9p. Clinical and cytogenetic aspects]
Summary
This study reports a new case of monosomy 9p in a newborn, a de novo deletion identified via banding techniques. Early recognition by neonatal staff is crucial due to distinctive features resembling Down syndrome.
Area of Science:
- Genetics
- Clinical Medicine
- Pediatrics
Background:
- Monosomy 9p is a rare chromosomal abnormality.
- Genetic deletions can lead to significant congenital anomalies.
- Accurate diagnosis is vital for appropriate infant care.
Observation:
- A newborn presented with morphological anomalies consistent with monosomy 9p.
- The chromosomal alteration was confirmed using banding techniques.
- Parents exhibited normal karyotypes, indicating a de novo event.
Findings:
- The case represents a new instance of monosomy 9p.
- The observed anomalies share similarities with previously reported cases and Down syndrome.
- The deletion was identified as a de novo occurrence.
Implications:
- Neonatal departments require thorough knowledge of monosomy 9p.
- Early diagnosis is feasible at birth due to characteristic features.
- Understanding this syndrome aids in timely intervention and management.
