What is the medical definition of autosomal dominant and autosomal recessive?

What is the medical definition of autosomal dominant and autosomal recessive?

Input required: In dominant disorders, the dominant member of the gene pair controls how the gene activities are expressed, so the other gene can carry the same or normal information.In recessive disorders, the normal gene compensates for the bad information in the other gene, allowing a person to function normally unless both genes carry the bad information. ...Read more

What is the difference between autosomal dominant and autosomal recessive inheritance?

What is the difference between autosomal dominant and autosomal recessive inheritance?

2 copies of genes: We all have two copies of each gene in our chromosomes. In autosomal dominant conditions you only need one copy of the gene to have the disease. In autosomal recessive conditions you need two copies in order to have the disease. It is called recessive because people with only one copy do not have the disease, that is the conditions recedes or is hidden. ...Read more

Is there a difference between autosomal dominant and autosomal recessive polycystic kidney disease?

Is there a difference between autosomal dominant and autosomal recessive polycystic kidney disease?

Yes: The dominant form occurs mostly in adults. It is inherited but it takes time to show up as a diagnosable disease in middle to later age. Depending on your luck you either have it from your parent or not( 50% chance).The recessive form could be carried by seemingly healthy persons and when manifests as a disease in the offspring, it shows up at a much earlier age. ...Read more

What are the differences between autosomal dominant and autosomal recessive polycystic kidney disease?

What are the differences between autosomal dominant and autosomal recessive polycystic kidney disease?

Differences: Main differences are---ADPKD shows itself in adults and 1/3 stays silent, 1/3 cause complications like hypertension etc, and 1/3 progress to end stage renal disease. ARPKD --- on the other hand manifests itself in pediatric population, in fact soon after birth, almost always involves kidneys bilaterally and requires dialysis for survival. Good news-- ADPKD is dominant therefore never skips generat ...Read more

Please help! what is the difference between autosomal dominant and autosomal recessive polycystic kidney disease?

Please help! what is the difference between autosomal dominant and autosomal recessive polycystic kidney disease?

Genes: There are caused by different loci. The recessive form generally causes illness from the time of birth due to the large, ineffective kidneys. The dominant form sneaks up on a person during adult life. The affected kidneys look different in the two diseases. ...Read more

How can a pedigree help you understand if a disease is autosomal dominant or recessive?

How can a pedigree help you understand if a disease is autosomal dominant or recessive?

See below: In brief, in case of a dominant gene, at least one of the parents has the relevant disease. In case of recessive gene both parents can be normal. See this site for an introduction to the topic.

Can you tell me how I could tell whether certain disorders are autosomal recessive, autosomal dominant, or x-linked?

Confusing question: If you are aware of the name of the disorder you can look it up.The NIH website has many such listings. Geneticists begin the process by compiling family trees of affected persons and sorting the issue out over time. ...Read more

Is a child with a autosomal recessive disease for sure going to be bad off?

Is a child with a autosomal recessive disease for sure going to be bad off?

Depends on the dz: This all depends on which disease the child has. Some autosomal recessive diseases can be relatively innocuous (e.g., mcardle's syndrome), whereas others can be quite serious (e.g., cystic fibrosis). The classification of "autosomal recessive" describes how the disease is inherited; it does not define the characteristics of the disease itself. ...Read more

How can I calculate carrier frequency of autosomal recessive conditions?

How can I calculate carrier frequency of autosomal recessive conditions?

Depends of the gene.: Different genes have different carrier frequency rates.
This site refers to the Hardy Weinberg equation. But more information is needed in order to complete the calculation.

Celiac autosomal recessive?

Celiac autosomal recessive?

Possibly: There are several gene-markers which make a person more likely but not certainly to develop celiac disease. It is certainly not sex-linked. Perhaps there are still other genetic markers or mutations required for one to develop the full-blown disease. ...Read more

What happens if a pedigree shows x linked recessive inheritance does it also show autosomal recessive inheritance?

What happens if a pedigree shows x linked recessive inheritance does it also show autosomal recessive inheritance?

No: X-linked recessive inheritance involves asymptomatic females passing a condition to their sons. An example is hemophilia A and B. Usually only males are affected.

Autosomal recessive inheritance affects both sexes equally. Two asymptomatic parents can pass a condition to their children 25% of the time on average. ...Read more

Is autosomal recessive polycystic kidney disease very serious?

Is autosomal recessive polycystic kidney disease very serious?

It is different: It usually is more serious than the autosomal dominant disease since it needs inheritance from both parents to be expressed i.e. Both genes are affected. It accordingly gets expressed at an earlier age in life. The longer duration of polycystic disease is a factor in predicting dialysis need. ...Read more

Does autosomal recessive polycystic kidney disease of one parent could be genetically transmissible to one of the children and what is the percentage?

Does autosomal recessive polycystic kidney disease of one parent could be genetically transmissible to one of the children and what is the percentage?

ARPKD: Autosomal recessive kidney disease will transmit to a child from a parent who has ARPKD only if both parents carry the trait. Percentage is low. ...Read more

I have calcium oxalate stones in my two kidneys and I have pkd, autosomal recessive kidney disease, please advice what type of food I should eat!

Oxalate stones: Studies show high intake of lemon citrate is essential. high intake of magnesium and potassium is essential. Low intake of salt and animal protein is essential. Take 5 teaspoons of ReaLemon extract per day. Eat tropical fruits such as mango, melons, kiwi, tomato. Drink 3-4 quarts fluid per day. Avoid caffeine. ...Read more

Is edward's syndrome autosomal or sex-linked? Dominant or recessive?

Is edward's syndrome autosomal or sex-linked? Dominant or recessive?

None of the above: Edward syndrome is brought on by an abnormality of chromosome numbers, specifically an extra 18. The abnormal egg with a single chromosome 1-17 & 19-22 + x has a pair of 18's. When the sperm brings a single chromosome 1-22 + x or y then the embryo ends up with 47 chromosomes rather than 46 in every cell.(3-18's) the excess distorts the organ building information & defects arise. ...Read more

Down syndrome is autosomal dominat?

Down syndrome is autosomal dominat?

No autosomal: Down syndrome happens when an extra 21 chromosome is present in all the cells of the body. It happens before conception when the donor egg fails to shed one of its 21 chromosomes in the formation of the egg & the male 21 joins the female pair & creates an embryo with 3 number 21's. It has nothing to do with traits or mutations in the gene code. ...Read more

Is obesity recessive or dominant?

Is obesity recessive or dominant?

It's complicated: There is no single gene for obesity. There are at least 30 different genes related to obesity (probably many more); some are recessive and some are dominant. but even amongst those who have a genetic predisposition, diet and lifestyle still play a major role. Not everyone with genetic tendencies to obesity become obese.
