We report the familial occurrence of the G syndrome of multiple congenital anomalies affecting a mother and her three sons. All showed the characteristic syndromal facies, a low total ridge count, pronounced hypertelorism, and mild mental retardation, and severe dysphagia in infancy which improved with age but persisted in the boys (it has disappeared in the mother). One of the boys had a left cleft lip and cleft palate, another had a unilateral cleft lip. All boys had hypospadias: penile in two (with descended testes) and perineal in another (with cryptorchidism). Familial occurrence in this family is compatible with autosomal dominant inheritance.

We describe a novel, biotin-responsive basal ganglia disease in 10 patients. At onset, it appears as a subacute encephalopathy, with confusion, dysarthria and dysphagia with occasional supranuclear facial nerve palsy or external ophthalmoplegia, and progresses to severe cogwheel rigidity, dystonia and quadriparesis. These symptoms disappear within a few days if biotin (5-10 mg/kg/day) is administered, and there are no neurological sequelae. They reappear within 1 month if biotin is discontinued. Patients diagnosed late, or who have had repeated episodes, suffer from residual symptoms such as paraparesis, mild mental retardation or dystonia. The numerous biochemical studies of intermediary metabolism, like the autoimmune and toxicological studies, enzyme assays including biotinidase, carboxylase and lysosomal activities, and bacterial and viral studies were all normal. The aetiology may be related to a defect in the transporter of biotin across the blood-brain barrier. The only consistent radiological abnormality was central necrosis of the head of the caudate bilaterally and complete, or partial, involvement of the putamen on brain MRI. This was present during the initial acute encephalopathy and remained unchanged during follow-up of 3-10 years. Although its aetiology is unknown, it is important to recognize this disease, since its symptoms may be reversed and the progression of its clinical course prevented simply by providing biotin.

Triple A (Allgrove) syndrome, an autosomal recessive disease is characterized by achalasia, alacrimia and ACTH-resistant adrenal failure with progressive neurological syndrome including central, peripheral and autonomic nervous system impairment, and mild mental retardation. The triple A syndrome gene, designated AAAS, localized on chromosome 12q 13 encodes for a 546 amino acid protein called ALADIN (Alacrimia-Achlasia-Adrenal Insufficiency and Neurologic disorder). This report relates to two sisters, aged 8 and 12 years, who had vomiting, muscle weakness, alacrimia, excessive fatigue and dysphagia. Abdominal sonography, esophago-gastroduodenoscopy, barium swallow, esophageal manometry, CT scan abdomen and brain, biochemical profiles, as well as neurologic and ophthalmic evaluations were consistent with Allgrove's syndrome. Management consisted of pneumatic balloon dilatation for achalasia and initiation of cortisone therapy with successful resolution of dysphagia and other symptoms.
