What DNA mutations are directly linked to inherited diseases?
Some common DNA mutations directly linked to inherited diseases include the CFTR gene mutation in cystic fibrosis, the BRCA gene mutations in breast and ovarian cancers, and the HTT gene mutation in Huntington's disease. These mutations can be inherited from one or both parents and increase the likelihood of developing the associated disease.
The BRCA 1 and BRCA 2 mutations increase the risk of which cancer in women?
BRCA1 and BRCA2 mutations increase the risk of breast and ovarian cancer in women. Women with these mutations have a higher lifetime risk of developing these cancers compared to those without the mutations.
Is a gene all of an organisms DNA or only a segment of DNA?
A gene is a portion on a chromosome. It is not the entire DNA which codes for all you see in an individual.
Is a gene all of an organism's DNA or only a segment of DNA?
A gene is a portion on a chromosome. It is not the entire DNA which codes for all you see in an individual.
Are the two copies of each gene in your body always the same?
yes. all of your cell have the same gene.
What does BRCA 2 control?
you can figure it out
What does BRCA stand for?
BRCA1 and BRCA2 are genes that can mutate into cancer.
Where is BRCA testing done?
It's usually done in hospitals.
What mutagen causes breast cancer?
Well the onco genes are BRCA-I and BRCA-II if mutated they cause breast cancer, I think that is what you meant, if not then you may have learned something new anyway

What is the most common cause for endometrial cancer?
The cause of breast cancer is not fully understood. Heredity or genetically related susceptibility is considered to play a role. Hormonal regulation of the breast is related to the development of breast cancer, but the mechanisms are poorly understood. Sex hormones (like estrogen) may act as a tumour promoters id initiating agents have induced malignant changes. Estrogen doesn't cause Breast Cancer, but the initiating agents that are found in a susceptible person may accelerate its growth. Additional factor under study include physical inactivity, dietary fat intake, obesity, and alcohol intake. Environmental factors such as chemical, pesticide, and radiation exposure may also play a role. Gene abnormalities may be inherited. 5 to 10 percent of all breast cancer persons inherit this gene. Tumour suppressor genes BRCA-1 gene, located in chromosome 17 is a tumour suppressor gene that inhibits tumor development when functioning normally. Women who have BRCA-1 mutations have a 50-85 percent lifetime chance of developing breast cancer. BRCA-2 is another culprit. BRCA tumor suppressor genes mutations may account for 10-40 percent of breast cancers.
How is testing for brca1 or brca2 different from testing for a gene such as the tay-sachs gene?
Testing for BRCA1 or BRCA2 genes primarily focuses on assessing an individual's risk for breast and ovarian cancers due to inherited mutations, which can significantly impact management and preventive strategies. In contrast, Tay-Sachs testing is aimed at identifying carriers of a specific mutation that leads to a fatal genetic disorder affecting neurological development, primarily in Ashkenazi Jewish populations. While BRCA testing often involves assessing family history and may lead to proactive measures, Tay-Sachs testing typically focuses on reproductive decisions for carriers. Additionally, BRCA mutations have a broader spectrum of implications for cancer risk, while Tay-Sachs is a single-gene disorder with a clear phenotype.
What does BRCA mean?
BRCA1 and BRCA2 are two genes in your DNA which when altered or mutated, leads to Breast cancer.
The combined alleles of all the individuals in a population is what?
The entire collection of genes among a population is called the "gene pool".
What does a gene do in a organism?
A gene has all the traits of the organism
How do the BRCA genes function differently in a person with the mutation?
The BRCA genes are involved in initiating DNA repair and cell cycle check points, they as as regulators of other tumour supressors genes such as p53 and help the cell repair and damage which may lead to cancer occurring in the cell. In mutant versions of the BRCA genes they cannot perform their roles and damaged DNA may cause the cell to replicate uncontrollably as check point to prevent this has been removed. Genome stabiliy is affected and cancer can develop
The collection of all the genes in a population is called?
The collection of all the genes in a population is called the gene pool. This gene pool contains all of the genetic variation within a population, which can be passed on to future generations through reproduction.
