3. Cause This disease is an autosomal RECESSIVE gene. Meaning there has to be 2 copies of the mutated or abnormal gene on the chromosome for the disease to be in the body. Chromosome 18 is affected by this. A healthy gene would break down fat and cholesterol and distribute the cells evenly around the body.

4. Cause Continued This is not a sex linked gene This is not a non-disjunction The only way this is inherited is when each parent has the gene on their chromosome 18. The gene may be there but not affect the parents.(Carriers) But when it is passed on to the offspring, it becomes present.
