 en Evidence for non-HFE linked hemochromatosis in Asian Indians
Panigrahi I, Ahmad F, Kapoor R, Sharma PK, Makharia G, Saxena R

Abstract

BACKGROUND: Hereditary hemochromatosis is commonly due to two HFE1 (Histone Family E1) gene mutations - H63D and C282Y. Mutations in the Asian Indians are less well studied.
AIMS: The aim of this preliminary study was to find out the prevalence of HFE gene mutations in nonviral liver cirrhosis patients.
SETTINGS AND DESIGN: Unexplained liver cirrhosis cases with transferrin saturation>45%, attending the gastroenterology clinic in the years 2004 and 2005 were subjects of the prospective study. Asymptomatic individuals with negative family history of hemolytic anemia or liver disease served as controls.
MATERIALS AND METHODS: The clinical presentation was recorded in the patients. Transferrin saturation was estimated by standard colorimetric technique. The two common mutations in HFE1 gene and Y250X mutation of TFR (transferrin receptor) gene were studied by polymerase chain reaction based methods.
RESULTS: A majority of the cases were sporadic, but family history was positive in four patients. In one family with multiple affected members, there was clear evidence of autosomal dominant inheritance. Seven out of 31 (22.6%) of unexplained cirrhosis cases were positive for mutations. One was homozygous for H63D. In healthy controls, prevalence was 8.1% (6/74). None of the patients or controls was positive for C282Y mutation of HFE1 or Y250X of TFR gene.
CONCLUSIONS: Thus, in a number of cases of hemochromatosis in Indians, a gene with dominant inheritance may be involved in causation of the phenotype. The prevalence of HFE mutations in Indians is comparable to that reported from neighboring countries. It is worth studying other mutations in HFE gene and other iron overload genes in cryptogenic cirrhosis cases.
