What makes some genes responsible for an increased risk of certain cancers?

Some genes, when they mutate, are more likely to cause cancer than others. For example, tumor suppressor genes, such as p53 or Rb (retinoblastoma), when mutated, can cause cells to lose control of their cell cycle and divide abnormally.

What chromosome is the BRCA2 gene on?
Breast cancer, as all cancers, is highly complex and caused by mutations in numerous genes - each cancer, however, will likely have different gene mutations.However, there are some genes which are commonly mutated in a small proportion of breast cancers (a mutation in these genes shows increased susceptibility in a number of families) - the most commonly referred to are BRCA1 and BRCA2.BRCA1 is found on 17q21 (chromosome 17, q arm, band 21) and BRCA2 on 13q12.
What are the genes responsible for the characteristics?
Genes are transcribed to make Proteins
What can increase a person's chance of getting cancer?
Being born with certain genes.
What causes between 80 percent to 90 percent of cancers?
1) Genetic predisposition to cancers 2) Dietary intake of foods, toxins, and chemicals leading to cellular/genetic damage or activating oncogenes or hindering cancer suppression genes 3) Environmental influences of toxins, chemicals, and radiation (all responsible for cellular/genetic damage...again, leading to activation of oncogenes or hindering of cancer suppression genes
What molecule are genes responsible for making?
Genes are the blueprints for making proteins.
How are dieseases inherited?
This means that you inherit certain genes from your parents; these genes can predispose you to a certain diseases. For example, you may be more vulnerable to certain bacteria, or the genes may directly related to some defect, such as sickle-cell anemia.This means that you inherit certain genes from your parents; these genes can predispose you to a certain diseases.

What is the most common mutation to genes?
p53 gene..approximately 50% of human cancers involve this mutation.
What is genes responsible for dengue fever?

Are genes are responsible for all the traits of an organism.?
no they are not.
Who is at increased risk for developing type 1 and type 2?
People who are overweight, inactive and have a family history are at an increased risk for type 2 diabetes. Certain races, those over 45 and women who have had gestational diabetes are also at an increased risk for type 2. For type 1 diabetes, those who have a family history, the presence of certain genes, and some geographical areas have an increased risk.
Cancer can sometimes be an inheritable disease?
Yes, cancer can sometimes have a hereditary or genetic component. Some individuals may inherit gene mutations from their parents that increase their susceptibility to developing certain types of cancer. These inherited genetic mutations are associated with an increased risk of cancer, but they do not guarantee that cancer will develop. There are certain genes known as tumor suppressor genes and oncogenes that play crucial roles in regulating cell growth and preventing the formation of tumors. Mutations in these genes can lead to uncontrolled cell growth and an elevated risk of cancer. Two common types of hereditary cancer syndromes are: Hereditary Breast and Ovarian Cancer (HBOC): Mutations in the BRCA1 and BRCA2 genes are associated with an increased risk of breast and ovarian cancers. Individuals with these mutations have a higher-than-average risk of developing these cancers, as well as an increased risk of certain other cancers. Lynch Syndrome (Hereditary Nonpolyposis Colorectal Cancer - HNPCC): This syndrome is caused by mutations in genes involved in DNA repair, such as MLH1, MSH2, MSH6, and PMS2. Lynch Syndrome is associated with an elevated risk of colorectal cancer and an increased risk of other cancers, including endometrial, ovarian, and stomach cancers. It's important to note that while hereditary factors can contribute to an increased risk of cancer, the majority of cancers are not directly inherited. Most cancers are believed to result from a combination of genetic, environmental, and lifestyle factors. If there is a family history of certain types of cancer, genetic counseling and testing may be recommended. Genetic testing can identify whether an individual carries specific mutations associated with an increased cancer risk. This information can help individuals and their healthcare providers make informed decisions about monitoring, prevention, and early detection strategies. If you have concerns about your risk of developing cancer based on your family history, it is advisable to discuss these concerns with a healthcare professional or a genetic counselor. They can provide guidance on genetic testing and help assess your individual risk factors.
