The findings of Tan et al. were confirmed by an independent study from Australia, in which the authors employed the 2H1 antibody and observed loss of parafibromin immunoreactivity in the majority of sporadic carcinomas (8/11; 73%) and HPT-JT-related tumours (3/4; 75%) as opposed to positive staining in benign tumours [21]. Here, CDC73 is linked to carcinoma.
