Krabbe disease is caused by an autosomal recessive Autosomal Recessive Genetic disorders determined by a single gene (Mendelian disorders) are easiest to analyze and the most well understood. If expression of a trait requires only one copy of a gene (one allele)... read more galactocerebroside beta-galactosidase deficiency. There are 4 forms: infantile, late infantile, juvenile, and adult.
