Genetic conditions (2024)

FAQs

What does it mean when we say someone has a genetic disease choose the best answer? ›

A genetic condition is caused by an altered gene or set of genes. The four broad groups of genetic conditions include single gene conditions, chromosome anomalies, mitochondrial conditions and multifactorial conditions.

Genetic disorders occur when a mutation affects your genes. Carrying the mutation doesn't always mean you'll end up with a disease.

A genetic condition occurs when you inherit an altered (changed) gene from your parents that increases your risk of developing that particular condition. However not all genetic conditions are passed down from your parents, some gene changes occur randomly before you are born.

Carrier Screening. Based on early studies, every person is estimated to carry approximately three to five genetic mutations. Carrying a mutation does not typically cause any related disorders for that person, but it can mean that their children are at risk for having a disorder.

In some cases, an affected person inherits the condition from an affected parent . In others, the condition may result from a new variant in the gene and occur in people with no history of the disorder in their family. In autosomal recessive inheritance , variants occur in both copies of the gene in each cell.

Genetics. ADHD tends to run in families and, in most cases, it's thought the genes you inherit from your parents are a significant factor in developing the condition. Research shows that parents and siblings of someone with ADHD are more likely to have ADHD themselves.

Angelman syndrome

A rare syndrome causing physical and intellectual disability. It can't be cured, but some therapies can improve the quality of life of those affected....

Approximately 2% to 3% of couples are carriers of the same condition. Although certain genetic conditions may be individually rare, collectively, their prevalence is more significant and accounts for more than 10% of pediatric deaths.

Is autism genetic? ›

Autism is highly heritable: It is estimated at least 50% of genetic risk is predicted by common genetic variation and another 15-20% is due to spontaneous mutations or predictable inheritance patterns. The remaining genetic risk is yet to be determined.

Many genetic disorders result from gene changes that are present in essentially every cell in the body. As a result, these disorders often affect many body systems, and most cannot be cured. However, approaches may be available to treat or manage some of the associated signs and symptoms.

There are well over 6,000 known genetic disorders, and new genetic disorders are constantly being described in medical literature. More than 600 genetic disorders are treatable. Around 1 in 50 people are affected by a known single-gene disorder, while around 1 in 263 are affected by a chromosomal disorder.

In pedigrees of families with multiple affected generations, autosomal recessive single-gene diseases often show a clear pattern in which the disease "skips" one or more generations. Phenylketonuria (PKU) is a prominent example of a single-gene disease with an autosomal recessive inheritance pattern.

Down syndrome is a genetic condition where a person is born with an extra chromosome. This can affect how their brain and body develop. People diagnosed with Down syndrome can lead healthy lives with supportive care.

A genetic disease is one that is caused by a change (mutation) in the genetic information of an individual that can be passed on from one generation to the next.

Sometimes there is a mutation, a change in a gene or genes. The mutation changes the gene's instructions for making a protein, so the protein does not work properly or is missing entirely. This can cause a medical condition called a genetic disorder. You can inherit a gene mutation from one or both parents.

Genetic disorders can be caused by a mutation in one gene (monogenic disorder), by mutations in multiple genes (multifactorial inheritance disorder), by a combination of gene mutations and environmental factors, or by damage to chromosomes (changes in the number or structure of entire chromosomes, the structures that ...

How many times have you heard someone say, “It's genetic”? Many people know the general meaning of what it means to have a genetic condition — it runs in the family.
