The epilepsy of trisomy 9p

Area of Science:

• Genetics
• Neurology
• Medical Imaging

Background:

• Trisomy 9p is a chromosomal disorder linked to brain abnormalities, neurological issues, and epilepsy.
• Previous literature lacks detailed descriptions of epilepsy in adults with trisomy 9p.

Observation:

• A 27-year-old male with trisomy 9p presented with complex partial epilepsy.
• Electroencephalogram (EEG) revealed multifocal independent spike discharges and asymmetric generalized spike discharges.
• Magnetic Resonance Imaging (MRI) showed white matter underdevelopment, corpus callosum and cerebellar atrophy, and a choroidal fissure cyst.

Findings:

• This is the first detailed report of epilepsy in an adult with trisomy 9p.
• The patient's EEG and MRI findings provide specific insights into the neurological manifestations of trisomy 9p.
• The observed brain structural abnormalities correlate with the patient's neurological dysfunction and epilepsy.

Implications:

• This case expands the understanding of trisomy 9p's neurological spectrum.
• Findings may aid in diagnosing and managing epilepsy in individuals with trisomy 9p.
• Highlights the importance of advanced neuroimaging in characterizing genetic disorders.
