Cystic fibrosis resulting when a person has mutations in both of the body's copies of the cftr gene; Suggestion that the mutant cftr gene persists so widely because of a heterozygote advantage; Suggestion from Gerald B. Pier and colleagues at Harvard Medical School in Boston, Massachusetts that...
What Is Cystic Fibrosis?The Cystic Fibrosis Gene
While ADHD is a complex disorder with several genetic and environmental causes working in concert, new research has discovered a gene that is linked... Learn more about this topic: Attention Deficit Hyperactivity Disorder: Definition of ADHD ...
What is autosomal gene expression? What is mutated in trisomy 21? Is PKU an autosomal recessive genetic mutation? Can a trait be sex-linked and autosomal? What chromosome has the genetic mutation for spina bifida? Is TP53 mutation genetic?
IgG Fc-binding protein (FCGBP) is also a component of the colon mucus and contains 13 vWDs, 12 cysteine-rich domains, and 12 trypsin inhibitor-like domains. TFF3 exists mainly as a heterodimer, while FCGBP is expressed and secreted by colon GCs as a partner protein linked to TFF3 by disu...
And then when I found out I had the gene, it was like, a gene! I felt like I wasn't a healthy person. . . . [Having the gene is] so much more complicated than not having the gene to me because now I know I have to go through all these other things—surgeries and worries ...
X-linked disorders: These disorders are caused by a mutated gene on the X chromosome. Some examples of X-linked disorders include hemophilia, Duchenne muscular dystrophy, and Fragile X syndrome. Monogenic diseases can range in severity from mild to severe. Some monogenic diseases are fatal, while...
Back to basics: mRNA Now that we have the code (or gene) for our example protein sequence,messenger RNA, or mRNA for short, steps in. It acts as the “go-between” from gene to protein — the “messenger” telling the cell’s ribosome what proteins to make — and is complementary to...
Is it possible for a Rh- woman and Rh+ man to have a RH- child? The genes for cystic fibrosis and blood group are not linked. Two parents are heterozygous for cystic fibrosis. One parent has blood group O and the other has blood group ...
What is paleopolyploidy? How does it contribute to the formation of gene families? How do genetic mutations occur? What are two examples of discoveries in genetics (besides epigenetics) that have led to the realization that genetic mapping is not as simple as genes being linked or not?
