BACKGROUND We, and others, have shown that experimenting with cigarettes is a function of both non-genetic and genetic factors. In this analysis we ask: how much of the total risk of experimenting with cigarettes, among those who had not experimented with cigarettes when they enrolled in a prospective cohort, is attributable to genetic factors and to non-genetic factors? METHODS Participants ...

Prescribers have been practicing stratified medicine for many years. Patient characteristics, usually non-genetic, including age, comorbidities and concomitant medications are taken into account when deciding which drug to prescribe. In addition, the majority of drugs require dose adjustments across patient subgroups, usually determined by non-genetic differences between the subgroups. Whilst p...

Background: Recreational drugs have a significant impact on the lives of drug users, their close families and friends, as well as their society. Social, psychological, biological, and genetic factors could make a person more prone to using recreational drugs. Finger and A-B ridges (dermatoglyphics) are formed during the first and second trimesters of fetal development, under the influence of en...

This team takes the position that what is commonly referred to as non-familial Alzheimer's disease (AD) is predominantly due to genetic factors. Population-based studies suggest that genetic factors cause the majority of cases that begin after age 60. There are several lines of evidence supporting this position: Data from the Nun Study suggest that the risk for AD is largely established by earl...

This study was conducted at the grasscutter section of the University of Education, Winneba, Ghana, to estimate effects of non-genetic factors on growth traits. Data consisted of records of 502 kids born from 136 does and 40 sires from 2006 to 2010. Feed intake increased (P<0.01) with increasing parity and years, whilst feed efficiency declined (P<0.01) with years. Animals consumed less (P<0.01...

The purpose of the present study is to provide guidelines regarding risk factors that may worsen the LongQT Syndrome (LQTS), based on available literature. This review evaluates the current knowledge on these risk factors of acquired LQTS, with an emphasis on non genetic risk factors, including environmental factors. PubMed was searched for literature in English from 1999 to 2011 on the molecul...

Quality grade of fed cattle is an important economic trait since approximately half of US fed cattle are marketed through value-based systems where carcasses are priced individually based on quality grade, yield grade and other factors. Quality grade of young cattle is primarily determined by marbling, a complex biological trait that has multiple controls and is not well understood. Once the ge...
