Title: FIC1 and BSEP defects in Taiwanese patients with chronic intrahepatic cholestasis with low gamma-glutamyltranspeptidase levels. Author: Chen HL, Chang PS, Hsu HC, Ni YH, Hsu HY, Lee JH, Jeng YM, Shau WY, Chang MH. Journal: J Pediatr; 2002 Jan; 140(1):119-24. PubMed ID: 11815775. Abstract: To elucidate the frequency of FIC1 (ATP8B1) and BSEP (ABCB11) mutations in Taiwanese children with chronic intrahepatic cholestasis with low gamma-glutamyltranspeptidase (GGT) levels, we assessed 13 unrelated patients with infantile onset chronic intrahepatic cholestasis. Liver complementary DNA sequencing was performed in 7 infants for mutation analyses of FIC1 and BSEP genes. Two distinct liver histologic features were found. Group 1 (n = 5) was characterized by bland cholestasis and group 2 (n = 8) by giant cell transformation. Group 2 patients were associated with higher transaminase levels, alpha-fetoprotein levels, and early mortality. Novel FIC1 mutations were found in all 4 patients tested in group 1, including a 74-bp deletion, a 98-bp deletion, a nonsense, and 2 missense mutations. BSEP mutations were found in 2 of the 3 patients in group 2, including 2 missense mutations and a 1-bp deletion. Phenotypic characterization is useful to differentiate FIC1- from BSEP-related disease.[Abstract] [Full Text] [Related] [New Search]
