Functional consequences of the human leptin receptor (LEPR) Q223R transversion.
Perturbations in the functional integrity of the leptin axis are obvious candidates for mediation of altered adiposity. In a large number of genetic association studies in humans, the nonconservative LEPR Q223R allele has been inconsistently associated with adiposity. Subtle, long-term effects of such genetic variants can be obscured by effects of the environment and other confounders that rend...

Polymorphism. A Hinf I PCR-RFLP was identified in the porcine leptin receptor ( LEPR) gene. Source and Description of Primers. Human cDNA (GenBank accession no. U43168) sequence was used to design primers to amplify porcine genomic DNA. Primer Sequences. Forward primer: 5¢GCATCCCATATCTGAACCC3¢; reverse primer: 5¢-CCACTTAAACCATAGCGAATC3¢.
متن کاملExonic and intronic sequence variation in the human leptin receptor gene (LEPR).
Increased adiposity is a major risk factor for cardiovascular disease and NIDDM (1). Genetic determinants of the degree of adiposity and body fat distribution have been demonstrated by twin and adoption studies, and the heritability (h) of obesity has been estimated to be as high as 0.90 (2). However, the major genes underlying the heritable contribution to body fatness in humans have remained ...
متن کاملEffects of leptin and cholecystokinin in rats with a null mutation of the leptin receptor Lepr(fak).
The Koletsky ("corpulent) obese rat is homozygous for an autosomal recessive mutation of the leptin receptor (Lepr) that results in hyperphagia, obesity, and hyperlipidemia. Unlike the Lepr mutation that characterizes the fatty Zucker rat (Lepr(fa)), the Koletsky mutation (Lepr(fak)) is null. Because the Lepr(fak) mutation is null, exogenous leptin should have no effect on body weight or food i...
متن کاملPooling analysis of genetic data: the association of leptin receptor (LEPR) polymorphisms with variables related to human adiposity.
Analysis of raw pooled data from distinct studies of a single question generates a single statistical conclusion with greater power and precision than conventional metaanalysis based on within-study estimates. However, conducting analyses with pooled genetic data, in particular, is a daunting task that raises important statistical issues. In the process of analyzing data pooled from nine studie...
