BACKGROUND Hepatitis C virus (HCV) infection is associated with the development of cirrhosis and hepatocellular carcinoma and is also related to fatty change of the liver. Variation in patatin-like phospholipase domain-containing 3 (PNPLA3) gene is associated with disease progression in nonalcoholic fatty liver disease (NAFLD). Recent reports have suggested that PNPLA3, IL28B and TLR4-associate...

BACKGROUND A genome-wide association study identified variants in or near patatin-like phospholipase domain-containing-3 (PNPLA3), neurocan (NCAN), lysophospholipase-like 1 (LYPLAL1), glucokinase regulatory protein (GCKR), and protein phosphatase 1 regulatory subunit 3b (PPP1R3B) that were strongly associated with nonalcoholic fatty liver disease (NAFLD) in adults of European ancestry. OBJECT...

Journal of Hepatology 20 group of heterozygous or homozygous subjects for the major allele (p = 0.02 for ALT and p = 0.01 for steatosis). Moreover, after weight loss, no differences among PNPLA3 genotypes were found in ALT levels or in the prevalence of steatosis (p = 0.1 and p = 0.2, respectively). Both the relationships between DBMI SDS and DALT and between DW/Hr and DALT were analysed, based...

Nonalcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease and has an estimated incidence of 20%–30% in the general population and 67%–75% in the obese population. Genetic predisposition can play an important role in development of this disease. Nonsynonymous coding SNP rs738409 C/G (I148Met) in the PNPLA3 gene has been found to be associated with the presence of...

AIM The adiponutrin gene family consists of five genes (PNPLA1-5) coding for proteins with both lipolytic and lipogenic properties. PNPLA3 has previously been associated with adult obesity. Here we investigated the possible association between genetic variants in these genes and childhood and adolescent obesity. METHODS/RESULTS Polymorphisms in the five genes of the adiponutrin gene family we...

The common PNPLA3 (adiponutrin) variant, p.I148M, was identified as a genetic determinant of liver fibrosis. Since the expression of PNPLA3 is induced by sterol regulatory element binding protein 1c (SREBP1c), we investigate two common SREBP1c variants (rs2297508 and rs11868035) for their association with liver stiffness. In 899 individuals (aged 17-83 years, 547 males) with chronic liver disea...

PURPOSE This study examined genetic associations of patatin-like phospholipase domain containing 3 gene (PNPLA3) polymorphisms and liver aminotransferases in an extensively documented, randomly recruited Mexican American population at high risk of liver disease. METHODS Two single nucleotide polymorphisms (SNP) in the PNPLA3 gene (i.e., rs738409 and rs2281135) were genotyped in 1532 individua...

The aim of this secondary analysis of a randomized controlled trial was to test whether the I148M variant of Patatin-like phospholipase domain-containing protein-3 (PNPLA3) is associated with the response to docosahexaenoic acid (DHA) in children with non-alcoholic fatty liver disease (NAFLD). Sixty children with NAFLD were randomized in equal numbers to DHA 250 mg/day, DHA 500 mg/day or placeb...

BACKGROUND AND AIM To evaluate if the presence of carotid atherosclerosis in patients with NAFLD, could be related to gene variants influencing hepatic fat accumulation and the severity of liver damage. METHODS We recorded anthropometric, metabolic and histological data(Kleiner score) of 162 consecutive, biopsy-proven Sicilian NAFLD patients. Intima-media thickness(IMT), IMT thickening(IMT≥1 ...

In normal weight subjects (body mass index < 25 kg/m2), non-alcoholic fatty liver disease (NAFLD) is likely to coexist with metabolic diseases. The patatin-like phospholipase 3 (PNPLA3) polymorphism rs738409 (c.444C>G) is associated with the risk of NAFLD and/or renal dysfunction; however, the influence of the weight status on the associations remains unknown. We aimed to clarify the associatio...
