Genetics includes the study of heredity, or how traits are passed from parents to offspring. The topics of genetics vary and are constantly changing as we learn more about the genome and how we are influenced by our genes.

Lesson Plans.A norm of reaction is a graph that shows the relationship between genes and environmental factors when phenotypic differences are continuous.

When the norm of reaction is not parallel, as shown in the figure below, there is a gene by environment interaction. This indicates that each genotype responds to environmental variation in a different way.

Environmental variation can be physical, chemical, biological, behavior patterns or life events. Gene—environment interactions are studied to gain a better understanding of various phenomena. In genetic epidemiologygene—environment interactions are useful for understanding some diseases.

Sometimes, sensitivity to environmental risk factors for a disease are inherited rather than the disease itself being inherited. Individuals with different genotypes are affected differently by exposure to the same environmental factors, and thus gene—environment interactions can result in different disease phenotypes. For example, sunlight exposure has a stronger influence on skin cancer risk in fair-skinned humans than in individuals with darker skin.

These interactions are of particular interest to genetic epidemiologists for predicting disease rates and methods of prevention with respect to public health.

Nature versus nurture debates assume that variation in a trait is primarily due to either genetic differences or environmental differences. However, the current scientific opinion holds that neither genetic differences nor environmental differences are solely responsible for producing phenotypic variation, and that virtually all traits are influenced by both genetic and environmental differences.

Statistical analysis of the genetic and environmental differences contributing to the phenotype would have to be used to confirm these as gene—environment interactions. In developmental genetics, a causal interaction is enough to confirm gene—environment interactions.

The history of defining gene—environment interaction dates back to the s and remains a topic of debate today. The first instance of debate occurred between Ronald Fisher and Lancelot Hogben.

Galat h Fisher sought to eliminate interaction from statistical studies as it was a phenomenon that could be removed using a variation in scale. Hogben believed that the interaction should be investigated instead of eliminated as it provided information on the causation of certain elements of development.

A similar argument faced multiple scientists in the s. Lewontin and Layzer argued that in order to conclude causal mechanisms, the gene—environment interaction could not be ignored in the context of the study while Jensen defended that interaction was purely a statistical phenomenon and not related to development.

Around the same time, Kenneth J. Rothman supported the use of a statistical definition for interaction while researchers Kupper and Hogan believed the definition and existence of interaction was dependent on the model being used.

In contrast to previous debates, Moffitt and Caspi were now using the statistical analysis to prove that interaction existed and could be used to uncover the mechanisms of a vulnerability trait. Contention came from Zammit, Owen and Lewis who reiterated the concerns of Fisher in that the statistical effect was not related to the developmental process and would not be replicable with a difference of scale.

There are two different conceptions of gene—environment interaction today. Tabery [11] has labeled them biometric and developmental interaction, while Sesardic [12] uses the terms statistical and commonsense interaction. The biometric or statistical conception has its origins in research programs that seek to measure the relative proportions of genetic and environmental contributions to phenotypic variation within populations. Biometric gene—environment interaction has particular currency in population genetics and behavioral genetics.

Biometric interaction is relevant in the context of research on individual differences rather than in the context of the development of a particular organism.Gene therapy involves altering the genes inside your body's cells in an effort to treat or stop disease.

Genes contain your DNA — the code that controls much of your body's form and function, from making you grow taller to regulating your body systems. Genes that don't work properly can cause disease.

Gene therapy replaces a faulty gene or adds a new gene in an attempt to cure disease or improve your body's ability to fight disease. Gene therapy holds promise for treating a wide range of diseases, such as cancer, cystic fibrosis, heart disease, diabetes, hemophilia and AIDS.

Researchers are still studying how and when to use gene therapy. Currently, in the United States, gene therapy is available only as part of a clinical trial. Gene therapy is used to correct defective genes in order to cure a disease or help your body better fight disease.

Gene therapy has some potential risks. A gene can't easily be inserted directly into your cells. Rather, it usually has to be delivered using a carrier, called a vector. The most common gene therapy vectors are viruses because they can recognize certain cells and carry genetic material into the cells' genes.

Researchers remove the original disease-causing genes from the viruses, replacing them with the genes needed to stop disease. The gene therapy clinical trials underway in the U.

Currently, the only way for you to receive gene therapy is to participate in a clinical trial. Clinical trials are research studies that help doctors determine whether a gene therapy approach is safe for people. They also help doctors understand the effects of gene therapy on the body. Your specific procedure will depend on the disease you have and the type of gene therapy being used. Viruses aren't the only vectors that can be used to carry altered genes into your body's cells.

Gene families

Other vectors being studied in clinical trials include:. The possibilities of gene therapy hold much promise. Clinical trials of gene therapy in people have shown some success in treating certain diseases, such as:.

But several significant barriers stand in the way of gene therapy becoming a reliable form of treatment, including:. Gene therapy continues to be a very important and active area of research aimed at developing new, effective treatments for a variety of diseases.
