Screening for hepatitis C in persons at high risk can lead to early identification of individuals at risk for progressive liver disease who may benefit from antiviral therapy and counseling to reduce HCV-related liver injury.
Background: A 25-year-old woman of English/Irish background was diagnosed with hemochromatosis. She manifested hypogonadotrophic hypogonadism and congestive heart failure. Although there were abnormal liver function tests, no cirrhosis was present. The patient has been treated intermittently by phlebotomy for 24 years. The aim of this study was to investigate the genetic basis of the patient’s iron overload disease. Methods: Genetic analysis was performed by direct sequencing of the genes for hemojuvelin, HFE, hepcidin, fer- roportin and transferrin receptor 2. Results and Con clusions: Molecular analysis showed that the patient was homozygous for a previously undescribed mutation of HJV, the gene encoding hemojuvelin. This mutation, nt 81G deletion, causes a frameshift encoding 23 additional irrelevant amino acids and premature termination. No mutations were found in the other hemochromatosis genes, hepcidin, HFE, ferroportin or transferrin receptor 2, which might have contributed to her iron overload.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
