FGF12 copy number variant associated with epileptic encephalopathy.

Area of Science:

• Genetics
• Neurology
• Epilepsy Research

Background:

• Epilepsy is a neurological disorder characterized by recurrent seizures.
• Genetic factors play a significant role in the etiology of various epilepsy syndromes.
• Fibroblast growth factor 12 (FGF12) has been implicated in certain forms of epilepsy.

Observation:

• This report details a patient with a duplication involving the FGF12 gene.
• The patient exhibited a phenotype consistent with previously described cases of FGF12-related epilepsy.
• Early developmental milestones were within the normal range for this patient.

Findings:

• The patient's epilepsy presentation was typical for FGF12 gene involvement.
• Phenotypic variability in FGF12 related epilepsy is noted.
• The patient demonstrated a positive response to phenytoin therapy.

Implications:

• This case contributes to the understanding of FGF12 related epilepsy phenotypes.
• It highlights the potential efficacy of phenytoin in managing this specific epilepsy subtype.
• Further research into FGF12's role in neurodevelopment and epilepsy is warranted.
