To investigate the loss of heterozygosity (LOH) at mitofusin-2 (Mfn2) gene in hepatocellular carcinoma (HCC) and its clinicopathological significance. Four high polymorphic microsatellite markers flanking Mfn2 were selected for LOH analysis in 29 cases of HCC. The frequencies of LOH on D1S2667, D1S2740, D1S434 and D1S228 were 21%, 23%, 21% and 22%, respectively. LOH at Mfn2 was closely correlated with tumor size, age, capsule, differentiation and t HBV infection (P<0.05), not with gender, thrombosis, cirrhosis and serum AFP levels (P>0.05). LOH at Mfn2 gene in HCC is associated with the clinicopathological features of patients.

D006528	Carcinoma, Hepatocellular	A primary malignant neoplasm of epithelial liver cells. It ranges from a well-differentiated tumor with EPITHELIAL CELLS indistinguishable from normal HEPATOCYTES to a poorly differentiated neoplasm. The cells may be uniform or markedly pleomorphic, or form GIANT CELLS. Several classification schemes have been suggested.

D019656	Loss of Heterozygosity	The loss of one allele at a specific locus, caused by a deletion mutation; or loss of a chromosome from a chromosome pair, resulting in abnormal HEMIZYGOSITY. It is detected when heterozygous markers for a locus appear monomorphic because one of the ALLELES was deleted.	Allelic Loss,Heterozygosity, Loss of,Allelic Losses,Heterozygosity Loss
