Hox genes: not enough room here to give good answer. I would go to wikipedia and then if you need more information go yto https://www.ncbi.nlm.nih.gov/pubmed/ and search hox genes AND reviews.

A 21-year-old member asked:

What genes play an important role in cerebrovascular disease?

2 doctor answers2 doctors weighed in
Dr. Michael Depietro
Pulmonary Critical Care 35 years experience
Many: Since there are many types of stroke, this is a very complicated question. Most strokes are related to atherosclerosis ( fat deposit in the arteries). So the genes involved ( there are many) in lipid (fat) metabolism and blood pressure regulation are important. One important set of genes seems to be located on chromosome number 9. In any case this is an active area of medical research.

Rarely one gene: Most strokes are due to risk factors such as hypertension, diabetes, and cholesterol issues have a genetic component that usually isn't localized to one gene. Familial clusters of strokes due to a single gene (eg cadasil) or single mitochondrial RNA mutation (eg melas) are rare.

How does a cell know which genes to turn on when?

1 doctor answer1 doctor weighed in
Dr. Richard Bensinger
Ophthalmology 52 years experience
Mostly unknown: We are aware that this happens and that the cell grows and matures by turning on and off genes. The biochemical means by which this is done is mostly unknown and is the subject of intense research. The answer to this probably will allow much improved therapy and probably ways to treat conditions such as cancer which involves the wrong genes being activated.

Dr. Thomas Marxen
Periodontics 36 years experience
Many: Many diseases and health conditions are influenced by genes. We have the technology today to do genetic testing from the blood which will provide genetic risk factors for many diseases eg heart disease, prostate cancer in men, breast cancer in women, lung cancer, and many other diseases and cancers.
