{Abstract}: Hyperekplexia (HPX) is a rare hereditary disorder characterized by an exaggerated startle reflex and neonatal hypertonia. It exhibits both autosomal dominant and autosomal recessive inheritance patterns, depending on the gene involved. It could be a fatal neurogenetic disorder, but it is treatable. We reported a nine-month-old female child with mild gross motor delay, an exaggerated startle reflex, and multiple episodes of transient hypertonia. Neurological and electrophysiological investigations and clinical presentation suggested the diagnosis of hereditary HPX. The child showed a good response to oral clonazepam, with a reduced frequency of such episodes and attainment of age-specific milestones.
