A form of functioning pancreatic neuroendocrine tumor characterized most commonly by a solitary, small pancreatic lesion that causes hyperinsulinemic hypoglycemia. Insulinoma can present at any age but the median age of diagnosis is in the fifth decade of life. Insulinoma is malignant in only 7-10% of cases and the most common sites of metastasis are the liver and lymph nodes. The etiology is unknown in most sporadic cases but somatic YY1 (14q32.2) variants are associated with insulinoma in some cases. Insulinoma originates in the islet beta cells that are equally distributed throughout the pancreas. When functioning, the tumor manifests with hypersecretion of insulin and consequently causes hypoglycemia. With the exception of insulinoma in MEN1, insulinoma is not hereditary.	Concept non-current

A form of generalised enchondromatosis with involvement of the spine (so called spondyloenchondromatosis). Spondyloenchondromatosis is a very rare skeletal dysplasia characterised by severe platyspondyly, and mild involvement of hands and feet. It is though to be inherited as an autosomal recessive condition. Dominant pattern of inheritance has been recently suggested.	Concept non-current

A form of genetic LCAT (lecithin-cholesterol acyltransferase) deficiency characterised clinically by corneal opacifications, and biochemically by significantly reduced HDL cholesterol and partial LCAT enzyme deficiency. The disease is very rare. Corneal opacities are progressive and are observed from an early age (adolescence or young adulthood) and sometimes result in visual impairment. These lesions are generally more severe than in complete LCAT deficiency and form a mosaic pattern of small dot-like grey-white opacities. Signs of atherosclerosis have only been reported in rare cases although patients have low HDL cholesterol levels. In patients with this disorder, alpha-LCAT activity is abolished, but beta-LCAT activity is preserved. Impaired enzyme function is thought to result in deposition of lipids in the cornea. The disease follows an autosomal recessive pattern of inheritance.	A component that is no longer current, useful, appropriate or acceptable.

A form of hereditary spastic paraplegia characterised by either a pure phenotype of slowly progressive spastic paraplegia of the lower extremities with bladder dysfunction and pes cavus or a complex presentation with additional manifestations including cerebellar signs, nystagmus, distal or generalised muscle atrophy and cognitive impairment. Age of onset is highly variable, ranging from early childhood to adulthood. White matter hyperintensity and cerebellar and spinal cord atrophy may be noted on brain magnetic resonance imaging in some patients.

A form of hereditary spastic paraplegia which usually presents in late adolescence or early adulthood as a pure phenotype of lower limb spasticity with hyperreflexia and extensor plantar responses, as well as mild bladder disturbances and pes cavus. Rarely, it can present as a complex phenotype with additional manifestations including epilepsy, variable peripheral neuropathy and/or memory impairment.

A form of hereditary spastic paraplegia with high intrafamilial clinical variability. Characterised in most cases as a pure phenotype with an adult onset (mainly the third to fifth decade of life, but that can present at any age) with progressive gait impairment due to bilateral lower-limb spasticity and weakness as well as very mild proximal weakness and urinary urgency. In some cases, a complex phenotype is also reported with additional manifestations including cognitive impairment, cerebellar ataxia, epilepsy and neuropathy. A faster disease progression is noted in patients with a later age of onset. Caused by mutations in the SPAST gene (2p24-p21), encoding spastin.
