Acute intermittent porphyria is the most frequent and the most severe form of the acute hepatic porphyrias (see this term). It is characterized by the occurrence of neuro-visceral attacks without cutaneous manifestations.

Abetalipoproteinemia/ homozygous familial hypobetalipoproteinemia (ABL/HoFHBL) is a severe form of familial hypobetalipoproteinemia (see this term) characterized by permanently low levels (below the 5th percentile) of apolipoprotein B and LDL cholesterol, and by growth delay, malabsorption, hepatomegaly, and neurological and neuromuscular manifestations.

Isolated hemihyperplasia is a rare overgrowth syndrome characterized by an asymmetric regional body overgrowth, involving at least one limb, and associated with an increased risk of developing embryonal tumors, principally nephroblastoma (see this term) and hepoblastoma.

Crisponi/cold-induced sweating syndrome is an autosomal recessive disorder characterized in the neonatal period by orofacial weakness with impaired sucking and swallowing resulting in poor feeding necessitating medical intervention. Affected infants show a tendency to startle, with contractions of the facial muscles in response to tactile stimuli or during crying, trismus, abundant salivation, and opisthotonus. During the first year, most infants have spiking fevers. These features, referred to as 'Crisponi syndrome' in infancy, can result in early death without advanced care. After the first 2 years, the abnormal muscle contractions and fevers abate, and most patients show normal psychomotor development. From childhood onward, the most disabling symptoms stem from impaired thermoregulation and disabling abnormal sweating, which can be treated with clonidine. Patients have hyperhidrosis, mainly of the upper body, in response to cold temperatures, and sweat very little with heat. Other features include characteristic facial anomalies, such as round face, chubby cheeks, micrognathia, high-arched palate, low-set ears, and depressed nasal bridge, dental decay, camptodactyly, and progressive kyphoscoliosis (summary by Hahn et al., 2010).For a discussion of genetic heterogeneity of Crisponi/cold-induced sweating syndrome, see CISS1 (OMIM ).

Ornithine transcarbamylase deficiency is an X-linked inborn error of metabolism of the urea cycle which causes hyperammonemia. The disorder is treatable with supplemental dietary arginine and low protein diet.Urea cycle disorders are characterized by the triad of hyperammonemia, encephalopathy, and respiratory alkalosis. Five disorders involving different defects in the biosynthesis of the enzymes of the urea cycle have been described: OTC deficiency, carbamyl phosphate synthetase deficiency (OMIM ), argininosuccinate synthetase deficiency, or citrullinemia (OMIM ), argininosuccinate lyase deficiency (OMIM ), and arginase deficiency (OMIM ).

Tyrosinemia type 1 (HTI) is an inborn error of tyrosine catabolism caused by defective activity of fumarylacetoacetate hydrolase (FAH) and is characterized by progressive liver disease, renal tubular dysfunction, porphyria-like crises and a dramatic improvement in prognosis following treatment with nitisinone.

Multiple endocrine neoplasia type IIB (MEN2B) is an autosomal dominant hamartoneoplastic syndrome characterized by aggressive medullary thyroid carcinoma (MTC), pheochromocytoma, mucosal neuromas, and thickened corneal nerves. Most affected individuals have characteristic physical features, including full lips, thickened eyelids, high-arched palate, and marfanoid habitus. Other more variable features include skeletal anomalies and gastrointestinal problems (review by Morrison and Nevin, 1996).For a discussion of genetic heterogeneity of multiple endocrine neoplasia (MEN), see MEN1 (OMIM ).
