Duffner et al. However, there are various difficulties in implementing this screening as a public health measure, since this disease is rare.
Another difficulty is foreseeing which phenotype the patient with a positive test will develop, since neither the level of enzyme activity nor the type of mutation predicts the clinical form. DK has a quick and lethal progression. Early diagnosis is fundamental for a good prognosis. HCT is more effective in the asymptomatic infantile and late onset forms, impeding neurological progression. Therefore, the earlier the diagnosis, the lower the incidence of neurological sequelae.

Center for Rare Disease Therapy. What is Krabbe Disease? Globoid Cell Leukodystrophy Krabbe disease "crab-A" is also known globoid cell leukodystrophy. Krabbe disease types There are two types of Krabbe disease: Infantile occurs in babies less than six months of age. Late-onset can happen at any other time. The effects of this disease can be severe, leading to death. Krabbe Disease Symptoms The symptoms of infantile Krabbe disease normally occur by the time a baby is six months old.
Some of the first symptoms of this disease include: Unusual fussiness or irritability Poor feeding Muscle weakness or stiffness Unexplained fevers As the disease progresses, other symptoms may include: Seizures Hearing loss Vision loss Nerve pain in the hands and feet Inability to move and swallow In late-onset Krabbe Disease, symptoms may include: Muscle weakness or stiffness Trouble walking Hearing or vision loss Seizures Decline in mental ability Diagnosing Krabbe Disease In some states, but not all, doctors routinely test newborns for Krabbe disease.
It's vital for treatment that doctors diagnose the disease as soon as possible. Krabbe Disease Treatment Right now, there is no cure for Krabbe disease. To make an appointment for your child or refer a patient for Krabbe disease care, contact us by: Phone at Email at rarecare chp.

In Krabbe disease, the short supply of GALC enzymes results in the accumulation of certain types of fats called galactolipids. Galactolipids normally exist in cells that produce and maintain the protective coating of nerve cells myelin. However, an abundance of galactolipids has a toxic effect.
Some galactolipids trigger myelin-forming cells to self-destruct. Other galactolipids are taken up by specialized debris-eating cells in the nervous system called microglia. The process of cleaning up excessive galactolipids transforms these normally helpful cells into abnormal, toxic cells called globoid cells, which promote myelin-damaging inflammation.
The subsequent loss of myelin demyelination prevents nerve cells from sending and receiving messages. To have an autosomal recessive disorder, you inherit two mutated genes, one from each parent. These disorders are usually passed on by two carriers. Their health is rarely affected, but they have one mutated gene recessive gene and one normal gene dominant gene for the condition. The gene mutation associated with Krabbe disease only causes the disease if two mutated copies of the gene are inherited.
A disease resulting from two mutated copies is called an autosomal recessive disorder. Genetic testing to understand the risk of having a child with Krabbe disease may be considered in certain situations:. Genetic testing should be carefully considered. Ask your doctor about genetic counseling services that can help you understand the benefits, limits and implications of genetic testing.
A number of complications — including infections and respiratory difficulties — can develop in children with advanced Krabbe disease. In the later stages of the disease, children become incapacitated, are confined to their beds and eventually lapse into a vegetative state.
Most children who develop Krabbe disease in infancy die before the age of 2, most often from respiratory failure or complications of immobility and markedly decreased muscle tone. Children who develop the disease later in childhood may have a somewhat longer life expectancy, usually between two and seven years after diagnosis.

Overview Krabbe KRAH-buh disease is an inherited disorder that destroys the protective coating myelin of nerve cells in the brain and throughout the nervous system.
