developmental and epileptic encephalopathy 97

Developmental and epileptic encephalopathy 97 is a neurodevelopmental disorder that affects multiple aspects of brain function, including cognition, language, and motor skills. The condition is associated with changes in the CELF2 gene, which plays a role in normal neuronal regulation. It is inherited in an autosomal dominant pattern and typically presents in early childhood with significant delays in speech, intellectual disability, and seizures. Precise prevalence estimates are not well established, and the variability in symptoms means that each child’s experience can differ considerably.

Individuals with developmental and epileptic encephalopathy 97 typically present with marked delays in speech and language development as well as intellectual disability, both of which are consistently observed. Neurological features are a prominent aspect of this condition with frequent reports of seizures and autistic behaviors, while other motor difficulties such as hypotonia, delayed motor milestones (including crawling, sitting, and walking), and poor head control are also seen in many affected children. Less common features include tremor, epileptic spasms, nystagmus, ventriculomegaly, and stereotypical hand wringing. Not all individuals experience all features, and severity varies considerably.

The genetic basis of developmental and epileptic encephalopathy 97 is linked to alterations in the CELF2 gene. This condition follows an autosomal dominant pattern, meaning that a single altered copy of the gene can be sufficient to cause the disorder. As a result, affected individuals have a 50% chance of passing on the variant to their offspring, although not every carrier may exhibit the full range of symptoms. Genetic counseling is recommended to help families understand the implications of this inheritance pattern.

Currently, management of developmental and epileptic encephalopathy 97 focuses on supportive care and symptom management, with treatment tailored to the individual’s specific needs. Given the complex nature of the condition, a multidisciplinary team approach is essential, often involving neurologists, developmental specialists, and therapists to monitor and address the various challenges over time. Regular surveillance for potential complications is recommended as part of long-term care. Patients and their families are encouraged to discuss treatment options and management strategies with their healthcare team to identify the best individualized approach.

The outlook for individuals with developmental and epileptic encephalopathy 97 is highly variable, with outcomes depending on the severity of symptoms, the age at diagnosis, and access to specialized care. With current standards of care, many individuals continue to benefit from multidisciplinary management and supportive interventions, although the condition remains lifelong. Outcomes described in medical literature continue to evolve as standards of care improve. Families often find it helpful to connect with specialists familiar with this condition and to seek genetic counseling for further guidance on prognosis and future planning.
