The cause of most parathyroid adenomas is unknown. However, about 10% are said to be hereditary. It can be the result of multiple genetic mutations in genes such as the calcium-sensing receptor gene, HRPT2 gene (CDC73 gene), Cyclin D1 gene (CCND1)/PRAD1 gene, MEN1 gene, and RET gene.
Parathyroid adenoma is idiopathic in approximately 90% of the individuals. However, approximately 10% of parathyroid adenoma are caused by mutation in genes.[1]
