Study Notes
Medical Conditions Resulting from Genetic Variants
- Haemophilia: A genetic disorder caused by a non-functioning gene located on the X chromosome. It is inherited in a recessive pattern, meaning an individual needs two copies of the affected gene to develop the condition.
- Sickle Cell Anemia: A genetic disorder caused by a mutation in the beta-globin gene, affecting the structure of red blood cells. It is inherited in an autosomal recessive pattern, meaning an individual needs two copies of the affected gene to develop the condition.
- Down Syndrome: A genetic disorder caused by the presence of an extra copy of chromosome 21. This condition is also known as trisomy 21.
Dental Conditions Resulting from Genetic Conditions
- Hypodontia: A condition where one or more permanent teeth are missing.
- Hyperdontia (Supernumerary): A condition where a person has more than the usual number of teeth.
- Microdontia: A condition where teeth are smaller than normal.
- Macrodontia: A condition where teeth are larger than normal.
- Macroglossia: A condition where the tongue is larger than normal.
- Amelogenesis Imperfecta: A condition where the enamel of the teeth is defective, making it weak and prone to wear.
- Dentinogenesis Imperfecta: A condition where the dentin of the teeth is defective, making it fragile and prone to breakage.
