Types of Genes

Biochemical Tests
Biochemical Tests

Biochemical genetic testing is the study of enzymes or proteins in the body that may be unusual in some way. These proteins or enzymes may work differently and lead to things such as birth defects in children.

Carrier Testing
Carrier Testing

Carrier testing is a type of genetic testing that is used to determine if a person is a carrier for a specific autosomal recessive diseases. This kind of testing is used most often by couples who are considering becoming pregnant to determine the risks of their child inheriting one of these genetic disorders.

Chromosomal Genetic Tests
Chromosomal Genetic Tests

Prenatal testing is used to detect changes in a fetus's genes or chromosomes before birth. This type of testing is offered during pregnancy if there is an increased risk that the baby will have a genetic or chromosomal disorder.

Chromosome 1 (Human)
Chromosome 1 (Human)

Chromosome 1 is the designation for the largest human chromosome. Humans have two copies of chromosome 1, as they do with all of the autosomes, which are the non-sex chromosomes. Chromosome 1 spans about 249 million nucleotide base pairs, which are the basic units of information for DNA.

Chromosome 2 (Human)
Chromosome 2 (Human)

Genes, which are made up of DNA, act as instructions to make molecules called proteins. In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases. The Human Genome Project has estimated that humans have between 20,000 and 25,000 genes.

Chromosome 3 (Human)
Chromosome 3 (Human)

Genes Number of genes. The following are some of the gene count estimates of human chromosome 3. Because researchers use different approaches to genome annotation their predictions of the number of genes on each chromosome varies (for technical details, see gene prediction).

Chromosome 4 (Human)
Chromosome 4 (Human)

Humans normally have 46 chromosomes in each cell, divided into 23 pairs. Two copies of chromosome 4, one copy inherited from each parent, form one of the pairs. Chromosome 4 spans about 191 million DNA building blocks (base pairs) and represents more than 6 percent of the total DNA in cells.

Chromosome 5 (Human)
Chromosome 5 (Human)

Identifying genes on each chromosome is an active area of genetic research. Because researchers use different approaches to predict the number of genes on each chromosome, the estimated number of genes varies. Chromosome 5 likely contains about 900 genes that provide instructions for making proteins.

Chromosome 6 (Human)
Chromosome 6 (Human)

Chromosome 6 is one of the 23 pairs of chromosomes in humans. People normally have two copies of this chromosome. Chromosome 6 spans more than 170 million People normally have two copies of this chromosome.

Chromosome 7 (Human)
Chromosome 7 (Human)

Chromosome 7 is one of the 23 pairs of chromosomes in humans. People normally have two copies of this chromosome. Chromosome 7 spans about 159 million base pairs and represents between 5 and 5.5 percent of the total DNA in cells.

Chromosome 8 (Human)
Chromosome 8 (Human)

Chromosome 8 is one of the 23 pairs of chromosomes in humans. People normally have two copies of this chromosome. Chromosome 8 spans about 145 million base pairs (the building material of DNA) and represents between 4.5 and 5.0% of the total DNA in cells.

Cystic Fibrosis,
Cystic Fibrosis,

Cystic fibrosis is a common genetic disease within the white population in the United States. The disease occurs in 1 in 2,500 to 3,500 white newborns. Cystic fibrosis is less common in other ethnic groups, affecting about 1 in 17,000 African Americans and 1 in 31,000 Asian Americans.

Diagnostic Testing
Diagnostic Testing

Diagnostic genetic testing can usually work out if you have a specific genetic condition that your provider is concerned about. It gives a “yes or no” answer. Your doctor may suggest a diagnostic genetic test if you have a medical problem.

Diagnostic Testing
Diagnostic Testing

Diagnostic genetic testing may help even if your doctor already has diagnosed the cause of your illness. Diagnostic testing can identify the particular genetic link to your condition. Overall, diagnostic test results can help you and your doctor make choices about your treatment and care.

Hemochromatosis
Hemochromatosis

Hereditary hemochromatosis is a disorder that causes the body to absorb too much iron from the diet. The excess iron is stored in the body's tissues and organs, particularly the skin, heart, liver, pancreas, and joints.

Huntington's Disease, and
Huntington's Disease, and

Huntington disease is a progressive brain disorder that causes uncontrolled movements, emotional problems, and loss of thinking ability (cognition). Adult-onset Huntington disease, the most common form of this disorder, usually appears in a person's thirties or forties.

Marfan Syndrome,
Marfan Syndrome,

Marfan syndrome is a disorder that affects the connective tissue in many parts of the body. Connective tissue provides strength and flexibility to structures such as bones, ligaments, muscles, blood vessels, and heart valves. The signs and symptoms of Marfan syndrome vary widely in severity, timing of onset, and rate of progression.

Molecular Genetic Tests (or Gene Tests)
Molecular Genetic Tests (or Gene Tests)

Genetic testing is a type of medical test that identifies changes in chromosomes, genes, or proteins. The results of a genetic test can confirm or rule out a suspected genetic condition or help determine a person’s chance of developing or passing on a genetic disorder.

Newborn Screening
Newborn Screening

Newborn genetic screening is a health program that identifies treatable genetic disorders in newborn infants. Early intervention to treat these disorders can eliminate or reduce symptoms that might otherwise cause a lifetime of disability.

Pre-Implantation Testing
Pre-Implantation Testing

Preimplantation genetic diagnosis (PGD) is a procedure used prior to implantation to help identify genetic defects within embryos. This serves to prevent certain genetic diseases or disorders from being passed on to the child.

Preimplantation Genetic Diagnosis (PGD) ... The following are considered benefits of PGD: PGD can test for more than 100 different genetic conditions.

Prenatal Testing
Prenatal Testing

When you’re pregnant, prenatal tests give you information about your health and your baby’s. They help detect any problems that could affect him, like birth defects or genetic diseases. The results can help you make the best health care decisions before and after your child is born.

Sickle Cell Anemia,
Sickle Cell Anemia,

Sickle cell disease is the most common inherited blood disorder in the United States, affecting 70,000 to 80,000 Americans. The disease is estimated to occur in 1 in 500 African Americans and 1 in 1,000 to 1,400 Hispanic Americans.
