Answer: Sickle cell disease is inherited, which means it is passed from parent to child. To get sickle cell disease, a child has to inherit two sickle cell genes-one from each parent. When a child inherits the gene from just one parent, that child has sickle cell trait. Having this trait means that you do not have the disease but you are a carrier and could pass the gene on to your children.
Answer: Canavan disease, also referred to as spongy degeneration of the CNS, is autosomal recessive, secondary to mutations in the aspartoacylase gene (ASPA). Symptoms typically begin two to four months after birth, with death occurring by 10 years of age
Answer: Cystic Fibrosis is an example of a disease inherited as an autosomal recessive genetic disorder. Both parents of a baby who has Cystic Fibrosis have one abnormal recessive gene and one normal dominant gene and are therefore, Cystic Fibrosis carriers. Carriers are said to be heterozygous because they contain one normal copy of the gene and one abnormal copy. A baby who inherits cystic fibrosis has inherited the abnormal gene from both parents and is therefore said to be homozygous recessive.
Answer: Sickle-cell anemia is characterised by abnormal haemoglobin which are not the correct shape and cannot carry oxygen.
It is a genetic disease - and a person must have two copies of the gene to have sickle-cell anemia. (Heterozygous individuals, with one copy, are known as having sickle-cell trait - and some of their haemoglobin may be misshapen).
