# data[].attributes.body
A genetic disorder that causes developmental and intellectual delays.

This is caused when there are 3 chromosome 21 instead of 2.

There is no cure for this disorder but it can be treated.

Intervention programs and therapy sessions are used to treat this disorder.

A disease in which mucus builds up in the lungs, pancreas and other vital organs.

This is an autosomal recessive gene disorder which means you need two copies of this trait to get the disease.

Symptoms include, pain in the abdomen, trouble breathing, wheezing, etc.

The treatment usually depends on the severity and sometimes there is no treatment.

# data[].attributes.body
A disease in which that destroys brain and spinal cord cells.
This disease is common in Jews.

This disease's pattern of inheritance is autosomal recessive.
In this disease a vital enzyme called hexosaminidase-A and in it's absence a lipid known as GM2 ganglioside accumulates in especially the brain cells which kills the cells.

This disease does not have a cure yet so this disease is fatal most of the time within 4 years.
Symptoms include feeling faint, muscle weakness, seizures.

A disease in which an blood cells are sickle shaped and are prone to rupturing and blockages.
This disease is common in African Americans.

Sickle Cell's pattern of inheritance is an autosomal incomplete dominance.
When you inherit two abnormal genes the you have Sickle Cell disease which is deadly.
Symptoms include pain in joints, chest, and fatigue.

When you only inherit only one abnormal gene then you have Sickle Cell Trait.
This rarely affects the person because the person produces both normal and abnormal cells.
The only ramification is that they can pass this gene to their children.

# data[].attributes.body
A disease in which nerve cells break down over time.

This is an autosomal dominant disorder so it is equally likely to affect both males and females.

Currently this disease is untreatable, and only the symptoms can be treated.

Symptoms include, paranoia, impulsive behaviour, and twitching.

# data[].attributes.body
A disorder in which blood does not clot normally.

This disorder is a recessive sex-linked disorder.

Symptoms include large bruises, unexplained bleeding, and urinating blood.

# data[].attributes.body
A birth defect that causes an amino acid called phenylalanine to build up in the body.

Caused when  a gene defect causes the enzyme, phenylalanine hydroxylase, not to be produced.
This causes the phenylalanine to build up because there are no enzymes to break it down.

PKU is an autosomal recessive trait disorder which means you need two copies of this gene to get it.
This can cause damage to the baby's brain due to phenylalanine buildup.
