What is genetic counselling?
Genetic counseling is the process that helps you in determining hereditary or genetic (running in your family) problems that might affect you or your family. It is done by a trained professional.
It involves the following steps:
- Checking or reviewing your medical history, family history, and pregnancy history
- Identifying and interpreting the increased risk of inherited disorders or passing on a hereditary disease to your unborn baby
- Suggesting and organizing genetic tests
- Evaluating and providing information about test results
- Providing information about management and prevention and helping in the decision-making process
Genetic counseling sessions may last for an hour and may vary based on your specific health problem and family history.
What causes a genetic disorder?
- Defects in the chromosomes (small bodies carrying reproductive instructions of a cell)
- Mutation (spontaneous permanent changes) in the DNA (a molecule carrying instructions of living being make-up)
- Environmental exposure to chemicals or radiation
- Developmental defect of the sperm or egg
- Recreational drug use for long term
- Industrial chemical exposure
How are genetic disorders treated?
Genetic disorders are mostly incurable. These are results of a change in genes that are the functional unit of body cells. They affect many organs. However, management of symptoms can be possible with the following approaches:
- Many genetic conditions occur due to inborn errors in metabolism. Avoiding certain substances in the diet may prevent the build-up of potentially toxic substances.
- Enzyme replacement therapy may help to manage the conditions or prevent future complications.
- Surgery for certain genetic conditions such as heart transplant for the birth heart defect, bone marrow transplant for defective blood cell formation diseases (sickle cell disease), cleft palate, and clubfoot may improve the particular symptoms associated with disorders.
- Familial breast cancer gene (BRCA1 and BRCA2) mutation (changes) can be screened in all family members and can be prevented by removing the cancer cells by breast surgeries before growing it as cancer.
- Most of the treatment strategies include gene therapy that is still in the experimental stage; this involves changing a person’s defective genes that may be helpful in the future for many genetic disorders.

Down SyndromeGet the facts on Down syndrome, a genetic disorder caused by an additional set of chromosomes in a developing fetus. Down syndrome signs and symptoms include distinctive facial features, growth retardation, and decreased mental function and IQ. Blood tests and ultrasound may be used to screen for Down syndrome but chromosome analysis of the fetus is needed to diagnose the condition. People with Down syndrome age more quickly and may develop Alzheimer's disease as young as age 40. Sometimes people are diagnosed with mosaic Down syndrome, in which case they have more than one type of chromosomal makeup.

Genetic DiseasesThe definition of a genetic disease is a disorder or condition caused by abnormalities in a person's genome. Some types of genetic inheritance include single inheritance, including cystic fibrosis, sickle cell anemia, Marfan syndrome, and hemochromatosis. Other types of genetic diseases include multifactorial inheritance. Still other types of genetic diseases include chromosome abnormalities (for example, Turner syndrome, and Klinefelter syndrome), and mitochondrial inheritance (for example, epilepsy and dementia).

What Is the Life Expectancy of Someone With Noonan Syndrome?There is a wide range in the severity of signs and symptoms in people with Noonan syndrome (NS). Therefore, the prognosis (long-term outlook) of this disease may vary in every case. The life expectancy of a person with NS is likely to be normal if serious heart defects are absent.
What Is the Life Expectancy of Someone with Williams Syndrome?Williams syndrome is a genetic disorder that affects approximately one in 25,000 births. Early intervention is the key to a long lifespan with this disease and can it also improve quality of life.
What Is the Life Expectancy of Someone With Osteogenesis Imperfecta?Osteogenesis imperfecta (OI) or brittle bone disease is a group of rare disorders characterized by extremely weak bones. The life expectancy of a person with osteogenesis imperfecta (OI) greatly depends on the type of the disease. In the most severe form of OI called type II or perinatally lethal OI, the baby is born with multiple broken bones. Those born with the less severe form of the disease, such as type I OI, may lead a healthy life. Their life expectancy is not shortened because of the disease.
What Are the 3 Functions of the Nucleus?The nucleus (pleural nuclei) is the most prominent and largest organelle in the cell. The three major functions of the nucleus include the regulation of cell metabolism and it serves as the site that houses the genetic material, DNA, as well as the site where RNA is produced.
While you cannot control your genes, gender, or age, you can increase your metabolism. Here are 7 ways to boost your metabolism.
What Foods to Avoid If You Have G6PD DeficiencyGlucose-6-phosphate dehydrogenase (G6PD) deficiency (G6PDD) is a genetic (hereditary) disorder. Therefore, you cannot prevent it. However, you can prevent the more serious G6PDD symptoms by avoiding certain foods such as fava beans, aniline dyes and certain medications.
What Is the Life Expectancy of Someone With Coffin-Siris Syndrome?Coffin-Siris syndrome (CSS) is a rare hereditary condition noticeable from birth (congenital). Most people with Coffin-Siris syndrome (CSS) live relatively long lives. The lifespan of affected individuals varies widely depending on the person’s level of physical and mental development and the severity of the illness. Medical care increases the quality of life and lifetime of people with CSS.
Who Is the Oldest Progeria Survivor?Tiffany Wedekind of Columbus, Ohio, is 45 years old as of 2023, making her the oldest survivor of progeria, also known as rapid aging disease. It is believed that Wedekind's progeria differs slightly from that of others with the disease, which explains her surprising age. The reason Tiffany Wedekind's progeria remained undiagnosed for so long was that she never had any health issues other than her teeth falling out. However, Wedekind has health problems and heart problems caused by progeria.
