Insights
Trisomy 12p syndrome can be associated with myoclonic absences, a type of seizure observed in a young patient. This finding suggests a potential link between chromosomal abnormalities and specific seizure types.
Area of Science:
- Genetics
- Neurology
- Pediatrics
Background:
- Trisomy 12p syndrome is a rare chromosomal disorder.
- Myoclonic absences are a specific type of epileptic seizure characterized by brief lapses of awareness and myoclonic jerks.
Observation:
- A 6-year-old female with trisomy 12p syndrome presented with typical myoclonic absences.
- Clinical and electroencephalogram (EEG) data confirmed the seizure type.
Findings:
- The patient's presentation suggests a correlation between trisomy 12p syndrome and myoclonic absences.
- This case adds to a small body of literature suggesting chromosomal abnormalities may cause specific seizure phenotypes.
Implications:
- Myoclonic absences may be a direct or indirect consequence of chromosomal disorders like trisomy 12p.
- Further research into chromosomal abnormalities and their neurological manifestations is warranted.
Abstract:
We report the case of a 6-year-2-month-old female affected by trisomy 12p syndrome. Seizures were typical myoclonic absences from both the clinical and EEG points of view. Our patient and other sporadic reports in the literature seem to support the hypothesis that, at least in some cases, myoclonic absences can be a direct or indirect effect of a chromosomopathy.
