BACKGROUND: IRF2BPL (interferon regulatory factor 2-binding protein-like) gene is an intronless gene present ubiquitously in the human body, including the brain.
Pathogenic variants lead to neurodegeneration and present with phenotypic features of a neurological disorder, including dyslexia, dyscalculia, epilepsy, dystonia, neurodevelopmental regression, loss of motor skills and cerebellar ataxia.
CASE: We present a case of a 9-year-old boy who was brought to the emergency department with generalised tonic-clonic seizures and mild hypotonia.
A history included neurological regression.
After insignificant lab and imaging results, the patient underwent genetic testing, revealing a novel pathogenic mutation in the IRF2BPL gene (heterozygous variant), which had never been reported in the literature before.
An autosomal dominant loss of function mutation was demonstrated, denoting in DNA as NM_0 24 496 c.911 C>T, which results in premature protein termination (p.Glu494).
CONCLUSION: Our case highlights the importance of early recognition of the neurological symptoms associated with various IRF2BPL gene mutations so that a timely multidisciplinary management approach can be provided.
