CC -!- DISEASE: Pheochromocytoma (PCC) [MIM:171300]: A catecholamine-producing
CC tumor of chromaffin tissue of the adrenal medulla or sympathetic
CC paraganglia. The cardinal symptom, reflecting the increased secretion
CC of epinephrine and norepinephrine, is hypertension, which may be
CC persistent or intermittent. {ECO:0000269|PubMed:11404820,

CC susceptibility is associated with variants affecting the gene

CC -!- DISEASE: Paragangliomas 4 (PGL4) [MIM:115310]: A neural crest tumor
CC usually derived from the chromoreceptor tissue of a paraganglion.
CC Paragangliomas can develop at various body sites, including the head,
CC neck, thorax and abdomen. Most commonly, they are located in the head
CC and neck region, specifically at the carotid bifurcation, the jugular
CC foramen, the vagal nerve, and in the middle ear.

CC -!- DISEASE: Paraganglioma and gastric stromal sarcoma (PGGSS)
CC [MIM:606864]: Gastrointestinal stromal tumors may be sporadic or
CC inherited in an autosomal dominant manner, alone or as a component of a
CC syndrome associated with other tumors, such as in the context of
CC neurofibromatosis type 1 (NF1). Patients have both gastrointestinal
CC stromal tumors and paragangliomas. Susceptibility to the tumors was
CC inherited in an apparently autosomal dominant manner, with incomplete
CC penetrance. {ECO:0000269|PubMed:17804857}. Note=The disease is caused
CC by variants affecting the gene represented in this entry.
CC -!- DISEASE: Mitochondrial complex II deficiency, nuclear type 4 (MC2DN4)
CC [MIM:619224]: A form of mitochondrial complex II deficiency, a disorder
CC with heterogeneous clinical manifestations. Some patients have
CC multisystem involvement of the brain, heart, muscle, liver, and kidneys
CC resulting in death in infancy, whereas others have only isolated
CC cardiac or muscle involvement with onset in adulthood and normal
CC cognition. Clinical features include psychomotor regression in infants,
CC poor growth with lack of speech development, severe spastic
CC quadriplegia, dystonia, progressive leukoencephalopathy, muscle
CC weakness, exercise intolerance, cardiomyopathy. Some patients manifest
CC Leigh syndrome or Kearns-Sayre syndrome. MC2DN4 is a severe, autosomal
CC recessive form characterized by early-onset progressive
CC neurodegeneration with leukoencephalopathy.
