abstract objective: thyroid dysfunction complicates the metabolic derangement observed in diabetes mellitus (dm). it is necessary to recognize and treat it, when present, in order to achieve stability of metabolic control in these patients. the aim of this study was to investigate the effect of dm on thyroid hormone levels and other biochemical variables. materials and methods: to determine the...
Pinus ponderosa and P. resinosa population samples have mean frequencies of enzymatically inactive alleles of 0.0031 and 0.0028 at 29 and 27 enzyme loci, respectively. Such alleles are rare and are apparently maintained by selection-mutation balance. Ponderosa pine have much higher amounts of allozymic and polygenic phenotypic variation than red pine, yet both species have similar frequencies o...
Much of the genetic basis of complex traits is present on current genotyping products, but the individual variants that affect the traits have largely not been identified. Several traditional problems in genetic epidemiology have recently been addressed by assuming a polygenic basis for disease and treating it as a single entity. Here I briefly review some of these applications, which collectiv...
At the present study, the observations of performance traits including body weight at 8 and 12 weeks of age, age at sexual maturity, egg weight and egg number were analyzed to detect major genes in Yazd native fowl. The probability of segregation for major genes was studied using simple tests including tests of normality, Bartlett, Levene and Fain for residuals and Bayesian analysis. Segregati...
In this project, we aimed to bring large-scale gene identification findings into a developmental psychopathology framework. Using a family-based sample, we tested whether polygenic scores for externalizing disorders-based on single nucleotide polymorphism weights derived from genome-wide association study results in adults (n = 1,249)-predicted externalizing disorders, subclinical externalizing...
This paper presents an extension of the finite polygenic mixed model of Fernando et al. (1994) to linkage analysis. The finite polygenic mixed model, extended for linkage analysis, leads to a likelihood that can be calculated using efficient algorithms developed for oligogenic models. For comparison, linkage analysis of 5 simulated 4021-member pedigrees was performed using the usual mixed model...
Sex-differences in human liver gene expression were characterized on a genome-wide scale using a large liver sample collection, allowing for detection of small expression differences with high statistical power. 1,249 sex-biased genes were identified, 70% showing higher expression in females. Chromosomal bias was apparent, with female-biased genes enriched on chrX and male-biased genes enriched...
An open question in human evolution is the importance of polygenic adaptation: adaptive changes in the mean of a multifactorial trait due to shifts in allele frequencies across many loci. In recent years, several methods have been developed to detect polygenic adaptation using loci identified in genome-wide association studies (GWAS). Though powerful, these methods suffer from limited interpret...
