The Reality of Treating Krabbe Disease in Newborn Infants
Hope is all any parent can ask for their infant with Krabbe disease. Of all newborn baby health problems, the only defense against it is hope and we intend to give it to you. We include optimistic sources to counter this overwhelming health problem your baby is experiencing.
We address the key questions surrounding Krabbe and neurodegeneration as you go through this struggle searching for a treatment to this rare childhood disease. The information in this article provides answers and resources to make life a little easier for you and your baby.
What is Krabbe Disease?
Krabbe is considered both a Leukodystrophy (affecting motor functions) and a disorder (affecting the nervous system). Krabbe’s neurological effects develop in newborn babies in early development. This early infantile sickness affects an estimated 1 out of every 100,000 births in the United States and 1 in every 170,000 births outside the US. Signs of this autosomal recessive disorder appear often before 6 months of age. In 2021, Krabbe’s neurodegeneration is considered fatal by age 2 by destroying an infant’s nerve cells in the brain and throughout the nervous system.
What Causes Krabbe In Newborn Babys?
Krabbe is an inherited genetic progressive disorder. This neurodegeneration is often referred to as a GalC deficiency. Mutations (globoid cell leukodystrophy) in the GalC gene (responsible for making the galactosylceramidase enzyme) result in the protective myelin enzyme breaking down. Without the nervous system’s myelin cover, the body sustains fatal damage. As this is an autosomal recessive disorder, if both parents carry this recessive disease, their child has a 1 in 4 chance of being born with this heartbreaking newborn baby health problem.
Symptoms of Krabbe
Symptoms develop at a rapid pace in a newborn infant’s first six months. There are mental and physical delays in development, muscle weakness, fever, and hyperirritability. The two most obvious symptoms in babies are regression of previously acquired motor functions i.e. difficulty walking, manual dexterity and swallowing followed by vision loss.
Other symptoms include but are not limited to, hearing loss, vomiting, spastic contractions in the lower extremities, and difficulty breathing. Prior to hearing loss, affected infants are hypersensitive to sound.
Diagnosing Krabbe in Infants
A series of tests are conducted to diagnose Krabbe.
Forms & Variations
Krabbe is a type of Leukodystrophy in two forms.
As many as 150 other mutations occur in the GalC gene. Not all lead to disease in newborn babies.

Treating Krabbe Disease
Krabbe disease has no cure, but there are treatments. GalC deficiency is treatable. Transplantation of Myelin-forming cells (Hematopoietic Stem Cell Transplant) has been pioneered by Dr. Maria Escolar in an effort to stabilize symptoms. Benefits are short term with best results in babies who are asymptomatic or mildly symptomatic. HSCT has not proven to correct the GalC deficiency in the peripheral nervous system of infants with a mortality rate of 15%.
