Is nonsyndromic paraganglioma inherited ?
Nonsyndromic paraganglioma can be inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to increase the risk of developing a paraganglioma or pheochromocytoma. People with mutations in the gene inherit an increased risk of this condition, not the condition itself. Not all people with this condition have a mutation in the gene, and not all people with a gene mutation will develop the disorder.  Most cases of nonsyndromic paraganglioma and pheochromocytoma are considered sporadic, which means the tumors occur in people with no history of the disorder in their family.
