Machado Joseph Disease

Machado Joseph disease is a genetic disorder affecting muscle movement and development. Unlike many other genetic diseases, only one parent needs to carry the gene to pass the condition onto children. ... read more »

How Do Genes Direct the Production of Proteins?

Most genes contain the information needed to make functional molecules called proteins. (A few genes produce other molecules that help the cell assemble proteins.) The journey from gene to protein is complex and tightly controlled within each cell. ... read more »

Common Genetic Conditions Due to Ethnicity

Some genetic disorders are more likely to occur among people who trace their ancestry to a particular geographic area. People in an ethnic group often share certain versions of their genes, which have been passed down from common ancestors. ... read more »

What Do Statistics Reveal About Genetic Conditions?

Statistical data can provide general information about how common a condition is, how many people have the condition, or how likely it is that a person will develop the condition. Statistics are not personalized, however, they offer estimates based on groups of people. ... read more »

How Chromosome Structure Affects Health and Development

Changes that affect the structure of chromosomes can cause problems with growth, development, and function of the body's systems. These changes can affect many genes along the chromosome and disrupt the proteins made from those genes. ... read more »

How Mitochondrial DNA Affects Health and Development

Mitochondria are structures within cells that convert the energy from food into a form that cells can use. Although most DNA is packaged in chromosomes within the nucleus, mitochondria also have a small amount of their own DNA. ... read more »
