Partial epilepsy and developmental delay in infant with ring chromosome 14.
Ring chromosome 14 (r14) causes early-onset epilepsy and developmental delays. Chromosomal analysis is crucial for diagnosing r14 in infants with unexplained seizures and developmental issues.
Area of Science:
- Genetics
- Neurology
- Pediatrics
Background:
- Ring chromosome 14 (r14) syndrome is a rare chromosomal disorder.
- It is associated with a distinct set of clinical features including early-onset epilepsy and developmental abnormalities.
Observation:
- A case of a female infant presenting with partial seizures and delayed development is described.
- The patient experienced afebrile generalized convulsions at 9 months, later evolving into complex partial seizures.
Findings:
- Karyotyping revealed the diagnosis of 46, XX, r(14) (p11.2q32.3).
- Despite the absence of consistent neuroimaging or EEG findings, clinical presentation and facial dysmorphisms aided diagnosis.
- Epilepsy in this patient was refractory to initial treatment, requiring adjustments in medication.
Implications:
- The study highlights the importance of chromosomal analysis in infants with unexplained refractory epilepsy and developmental delay.
- Early diagnosis of ring chromosome 14 syndrome can facilitate timely management and genetic counseling.
- Pediatric neurologists should consider chromosomal abnormalities when faced with complex neurological presentations in infancy.

Seizures: Classification
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:
