One case of misdiagnosis of 22q11.2 deletion syndrome with ovarian mixed germ cell tumor / 中华内分泌代谢杂志

Idiopathic hypoparathyroidism is a rare endocrine disease. It is often manifested as neuropsychiatric symptoms, especially epileptic seizures. Thus, it is easy to be misdiagnosed as primary epilepsy. The following case report details the diagnosis of a 17-year-old girl who had been misdiagnosed as primary epilepsy for a long time. She was found hypoparathyroidism during the hospitalization for the operation of ovarian mixed germ cell tumor. After whole exome sequencing, she was ultimately diagnosed as 22q11.2 deletion syndrome. This case suggested that clinicians should be aware of the possibility of hypoparathyroidism in adolescent epilepsy, especially hereditary hypoparathyroidism. At the same time, the possible high risk of tumors should also be considered in hereditary hypoparathyroidism.

Epilepsy and Other Neuropsychiatric Manifestations in Children and Adolescents with 22q11.2 Deletion Syndrome

BACKGROUND AND PURPOSE: 22q11.2 deletion syndrome (22q11.2DS) is the most common microdeletion syndrome. Epilepsy and other neuropsychiatric (NP) manifestations of this genetic syndrome are not uncommon, but they are also not well-understood. We sought to identify the characteristics of epilepsy and other associated NP manifestations in patients with 22q11.2DS. METHODS: We retrospectively analyzed the medical records of 145 child and adolescent patients (72 males and 73 females) with genetically diagnosed 22q11.2DS. The clinical data included seizures, growth chart, psychological reports, development characteristics, school performance, other clinical manifestations, and laboratory findings. RESULTS: Of the 145 patients with 22q11.2DS, 22 (15.2%) had epileptic seizures, 15 (10.3%) had developmental delay, and 5 (3.4%) had a psychiatric illness. Twelve patients with epilepsy were classified as genetic epilepsy whereas the remaining were classified as structural, including three with malformations of cortical development. Patients with epilepsy were more likely to display developmental delay (odds ratio=3.98; 95% confidence interval=1.5-10.5; p=0.005), and developmental delay was more common in patients with structural epilepsy than in those with genetic epilepsy. CONCLUSIONS: Patients with 22q11.2DS have a high risk of epilepsy, which in these cases is closely related to other NP manifestations. This implies that this specific genetic locus is critically linked to neurodevelopment and epileptogenesis.
