Study Notes
Heterozygous Gene
- A heterozygous individual possesses two different alleles for a gene.
Genetic Mutations
- Common causes include DNA damage from toxins and UV radiation.
- Inheritance of altered genes from either parent also contributes.
X-linked Recessive Disorders
- A father with an X-linked recessive disorder will pass the carrier state to his daughters.
Multifactorial Disorders
- Multifactorial disorders result from complex interactions of genetic and environmental factors.
Positive Genetic Mutation Test
- A positive genetic mutation test indicates a gene alteration was found.
- It suggests a genetic disease predisposition and potential risk for other family members.
- It does not guarantee the development of the disease.
Pharmacogenomics
- Pharmacogenomics assesses how single genes affect drug responses and variability.
- This information can be used assess the effectiveness of a drug.
Hemophilia A
- If a couple has one child with Hemophilia, and they have a second child it is a 50% chance the child will be a carrier, if female. If male it will be a 100% chance the child will have hemophilia.
