Krabbe disease is a genetically inherited neurological disorder. What Are The Symptoms Of Krabbe Disease? . It is estimated that Krabbe Disease affects approximately 1 out of every 100,000 people worldwide. Krabbe's Leukodystrophy is a hereditary disorder transferred to offspring through recessive genes. These babies quickly stop developing normally and often die before the age of two. Krabbe disease (KD) is caused by mutations in the galactosylceramidase (GALC) gene, which encodes a lysosomal enzyme that degrades galactolipids, including galactosylceramide and galactosylsphingosine (psychosine). 1 As with many lysosomal storage disorders, babies appear normal for the first few months of life then begin to develop noticeable symptoms. Death occurs at an average age of 13 months. Newborn screening allows us to diagnose Krabbe disease before the onset . Courtesy Clausen family. The most common forms of Aicardi-Goutières syndrome and PMD display symptoms from birth or within the first few months of life. This condition is very rare. Infantile Krabbe Disease Prenatal\Newborn Screening Diagnosis. Signs and symptoms begin before 6 months of age and include. High levels of galactolipids destroy the protective covering of nerve cells called myelin. Due to the poor specificity of GALC for the diagnosis of Krabbe disease, second-tier testing services were provided to reduce the false positive rates for disease monitoring. Cases of infantile Krabbe disease have reported an average onset of clinical deterioration between 3 to 14 months of . In conjunction with genetic counseling, this knowledge may also allow relatives of patients with Krabbe disease to be tested for the presence of the genitic mutation responsible .

This is an increased disease prevalence of Krabbe disease compared to the currently reported rate of one in 250,000 in the United States and one in 100,000 in Europe 45,46. As a result, there is an accumulation of the toxic compound psychosine principally in the central and peripheral nervous systems, which leads to widespread neurological symptoms. Parents are considered "carriers" if they have one abnormal copy of the GALC gene and one normal copy. Symptoms include irritability, unexplained fever . Krabbe is classified both as a leukodystrophy and as a lysosomal storage disorder. Within the first few months of life, affected babies begin to show symptoms.
