Gaucher Disease

Gaucher disease is a genetic disorder characterized by the accumulation of glucocerebroside due to a deficiency in the glucocerebrosidase enzyme, which is typically treated through enzyme replacement therapy.

Similarities to Other Organisims with this mutation

affects chromosome 1q21
two copies of the N370S mutation of the GBA gene
Gene Mutation
genotypes (N370S) encodes an enzyme that has sufficient residual enzyme activity to ensure that significant neurologic disease does not occur
death
anemia
Bone damage
jaundice
Fatigue
Pain
glucocerebrosidase

Fat Accumulates in:

Bone Marrow

Spleen

Liver

glucocerebroside fat can't be broken down

multifactorial inheritance disorders
Alzheimer's disease
Cancer
Monogenetic Inheritance Disorders
Cystic fibrosis

Life expectancy only into their 50's

Patterns of Evolution

Types of Gacuher Disease
Type 3 is chronic neuronopathic

It is treatable

primary central nervous system involvement,

eye movement disorders

seizures

liver and spleen enlargement

breathing problems

blood disorders

skeletal problems

Type 2 is called acute neuronopathic

primary central nervous system involvement

neurological impacts

abnormal accumulation of glucocerebroside in the brain

affects newborns and infants

It is fatal

Type 1 is called non-neuronopathic

lack of primary central nervous system involvement

don't have enough platelets in their blood

Proteins in blood

How platelets function

possibly kidney, lung, and skeletal problems

enlarged liver or spleen

bruise easily and feel tired often

history of excessive or prolonged bleeding

Subtopic

Surgical procedure

Minor cut

Women more prone than men

Skin becomes thinner

Some dietary supplements, such as ginkgo biloba, have a blood-thinning effect.

Corticosteroids thin the skin, making it easier to bruise

protective fatty layer that helps cushion blood vessels from injury gets thinner

Blood leaks out of vessels and appears as dark matter under the skin.

Small blood vessels (cappilaries) are broken

Arms

Legs

Blow/Injusry

It is treatable.

affects 90% of people

Treatment
glucocerebrosidase enzyme given intravenously
enzyme replacement therapy
Population Affected
Ashkenazi Jewish population 1 in 500 persons
affects approximately 1 in 100,000 persons

How the Mutation Arose

increased risk of developing Parkinson disease and related disorders
it is an autosomal recessive inherited disorder that affects the metabolism
passed down from parent to child
Transmission from carrier parents

1 in 4 (25 percent) chance to have a child who is neither affected nor a carrier

1 in 2 (50 percent) chance to have a child who is a carrier like themselves

1 in 4 (25 percent) chance to have a baby born with Gaucher disease

lack of phenotypes
verified by a beta-glucosidase leukocyte (BGL) test
50% of people diagnosed are under the age of 20
GBA gene (glucosylceramidase beta)
