Diseases

Disease IDSourceNameDescription
606864 OMIMParaganglioma and gastric stromal sarcoma (PGGSS)Gastrointestinal stromal tumors may be sporadic or inherited in an autosomal dominant manner, alone or as a component of a syndrome associated with other tumors, such as in the context of neurofibromatosis type 1 (NF1). Patients have both gastrointestinal stromal tumors and paragangliomas. Susceptibility to the tumors was inherited in an apparently autosomal dominant manner, with incomplete penetrance. The disease is caused by variants affecting the gene represented in this entry.
115310 OMIMParagangliomas 4 (PGL4)A neural crest tumor usually derived from the chromoreceptor tissue of a paraganglion. Paragangliomas can develop at various body sites, including the head, neck, thorax and abdomen. Most commonly, they are located in the head and neck region, specifically at the carotid bifurcation, the jugular foramen, the vagal nerve, and in the middle ear. The disease is caused by variants affecting the gene represented in this entry.
171300 OMIMPheochromocytoma (PCC)A catecholamine-producing tumor of chromaffin tissue of the adrenal medulla or sympathetic paraganglia. The cardinal symptom, reflecting the increased secretion of epinephrine and norepinephrine, is hypertension, which may be persistent or intermittent. Disease susceptibility is associated with variants affecting the gene represented in this entry.
