This is a case report of a patient, who was diagnosed with epilepsy (atypical infantile convulsions) at the age of one year and unspecific myopathy at the age of three years. At the age of 25 years, the patient was referred to a neuromuscular clinic due to myopathy, but the diagnose was changed to atypical infantile convulsions with seizures in adulthood and paroxysmal choreoathetosis due to a pathogenic variant c.970G>A, p. (Gly324Arg) in the PRRT2 gene.

Neuroblastoma is a malignant tumor derived from the neural crest cells that often involves the adrenal glands and rarely metastasizes to the skin. Here, we present a case of a nine-month-old male infant who presented with multiple noncompressible blue-purple subcutaneous nodules, initially suggestive of atypical deep hemangiomas. The ultrasound revealed a lack of increased vascularity of the masses and an adrenal mass, leading to a biopsy and diagnosis of a neuroblastoma involving the adrenal gland, liver, and skin.

Deleterious variations in are responsible for early infantile epileptic encephalopathy type 4 (EIEE4, OMIM # 612164) because of its dysfunction in the central nervous system. The clinical spectrum of the neurodevelopmental delays associated with STXBP1 aberrations is collectively defined as encephalopathy (-E), the conspicuous features of which are highlighted by early-onset epileptic seizures without structural brain anomalies. A girl was first diagnosed with unexplained disorders of movement and cognition, which later developed into -E with unexpected leukoaraiosis and late onset of seizures.

To summarize the clinical features of epilepsy and (or) developmental delay associated with KCNB1 gene variants in children. A case series study was conducted on 24 children with KCNB1 gene variants associated with epilepsy and (or) developmental delay who were treated at the Children's Medical Center of Peking University First Hospital and the Department of Neurology of Shenzhen Children's Hospital from July 2015 to June 2024. The manifestations of seizures, electroencephalogram (EEG) and genetic test results of those children were analyzed.
