This specific mutation in mitochondrial ND1 has been reported in oncocytic thyroid carcinoma [29], oncocytic pituitary adenoma [30], renal oncocytoma, and chromophobe RCC (eosinophilic variant) [28], suggesting that C3572ins mutation in ND1 is associated with oncocytic tumors or variants. The gene discussed is MT-ND1; the disease is Thyroid Gland Oncocytic Follicular Carcinoma.
