X-linked lissencephaly with abnormal genitalia (XLAG) is characterized by lissencephaly, absent corpus callosum and ambiguous genitalia. We examined hypothalamic dysfunctions in a XLAG case with a novel mutation of the ARX gene, and performed immunohistochemical evaluation of the diencephalons in autopsy brain. A 1-year-old boy showed intractable epilepsy, persistent diarrhea and disturbed temperature regulation. This case had abnormalities in circadian rhythms and pituitary hormone reserve test. He died of pneumonia. The globus pallidus and subthalamic nucleus was not identified, and the putamen and thalamus were dysplasic. The suprachiasmatic nucleus was absent. A few neurons immunoreactive for vasopressin seemed to form the ectopic supraoptic-like nucleus. The diencephalons were disturbed differently in each sub-region, and the changes may be related to various hypothalamic dysfunctions.

Hyponatremia is the most frequent electrolyte disorder in critically ill neurological patients. The major differential diagnoses in this situation are the syndrome of inappropriate antidiuretic hormone secretion, marked by inappropriate retention of free water, and cerebral salt wasting, characterized by excessive urinary loss of sodium and resulting in polyuria and extracellular volume contraction. Cerebral salt wasting is a syndrome of hyponatremia due to increased urine output and excessive natriuresis described in patients with central nervous system disease. Although cerebral salt wasting has been well described in neurosurgical patients, data regarding pediatric patients is sparse. We present a 34-month-old boy with lissencephaly who developed cerebral salt wasting after brain biopsy. The patient was treated with hypertonic saline and multiple antiepileptic drugs. Fludrocortisone supplementation effectively treated cerebral salt wasting.

Gene mutation of tubulin alpha-1A (TUBA1A), a critical component of microtubules of the cytoskeleton, impairs neural migration and causes lissencephaly (LIS). The approximately 45 cases of disease-associated TUBA1A mutations reported to date demonstrate a wide spectrum of phenotypes. Here we describe an 8-year-old girl with lissencephaly, microcephaly, and early-onset epileptic seizures associated with a novel mutation in the TUBA1A gene. The patient developed Hirschsprung disease and the syndrome of inappropriate antidiuretic hormone secretion (SIADH), which had not previously been described in TUBA1A mutation-associated disease. Our case provides new insight into the wide spectrum of disease phenotypes associated with TUBA1A mutation.
