if both parents are cf carriers?

An individual must inherit two non-functioning CF genes – one from each parent – to have CF. If both parents are carriers there is a 1 in 4 (25 percent) chance that both will pass on the non-functioning gene, which would result in a pregnancy affected with cystic fibrosis.

Because of this, people diagnosed with cystic fibrosis are prone to chronic infections — which is what leads into the premise of Five Feet Apart. People with the disease are at higher risk of cross-infection, which can lead to serious or even life-threatening infections.

If your parents don't have it but a brother or sister does, you have about 5% chance of getting type 1. That's about the same as if your father had it. If your identical twin has it, though, your odds may be as high as 50%.

You also need to choose someone to be your parents' agent. This is the person who will hold power of attorney over them. Thus, it has to be someone you can trust. Essentially, this should be their spouse and then you.

While a child could have the same blood type as one of his/her parents, it doesn't always happen that way. For example, parents with AB and O blood types can either have children with blood type A or blood type B. These two types are definitely different than parents' blood types!

If you or your partner has CF or is a CF carrier, you can have a prenatal test to find out if your baby has the condition or is a carrier. You can have either of these tests: Chorionic villus sampling (also called CVS). This test checks tissue from the placenta to see if a baby has a genetic condition, like CF.

The Punnett square below makes it clear that at each birth, there will be a 25% chance of you having a normal homozygous (AA) child, a 50% chance of a healthy heterozygous (Aa) carrier child like you and your mate, and a 25% chance of a homozygous recessive (aa) child who probably will eventually die from this ...

Each parent carries a gene for green (y) and a gene for yellow (Y). Place one parent's genes along the top of the Punnett square and the other parent's genes along the left side. Copy the genes down the columns and across the rows. Each of the four squares now shows a possible genotype combination.

If she gets the X chromosome with the hemophilia gene, she will have hemophilia. A man who has hemophilia and a woman who is a carrier have: a 25% (one in four) chance of having a son with hemophilia. a 25% chance of having a son with normal blood clotting.

Humans have two versions of all autosomal genes, called alleles, one from each parent. The recessive trait is hidden in the heterozygous individual (Dd) if the other allele is inherited in a dominant fashion, and so this person is a called a “carrier” of the recessive allele, but does not manifest the disease or trait.

Fathers pass down the altered BRCA gene at the same rate as mothers. When a parent carries the mutated gene, he or she has a 50 percent chance of passing it onto a son or daughter.

PAH can be hereditary or run in families. A gene called BMPR2 has been linked to familial pulmonary hypertension. Although the inheritence is autosomal dominant (one defective gene copy is enough to cause disease), only about 20% of patients with a bad gene copy develop the disease.

Newborn screening (NBS) for cystic fibrosis is done in the first few days after birth. By diagnosing CF early, CF health care providers can help parents learn ways to keep their child as healthy as possible and delay or prevent serious, lifelong health problems related to CF.

A couple are both phenotypically normal, but their son suffers from hemophilia, a sex-linked recessive disorder. ... Since the mother is a carrier, half of her X chromosomes will have the hemophilia gene and the other half will be normal. Therefore half of their sons are likely to have hemophilia.

Research suggests that cystic fibrosis contributes to low birth weight. Newly published research funded by the Cystic Fibrosis Trust has shown that babies with cystic fibrosis (CF) are born weighing less than babies without the condition, even allowing that they are more likely to be born prematurely.
