Galactosidase alpha is involved in the hydrolysis of terminal, non reducing alpha D galactose residues in alpha D galactosides, including galactose oligosaccharides, galactomannans and galactohydrolase. Defects in GLA are the cause of Fabry's disease (FD). FD is a rare X-linked sphingolipidosis disease where glycolipid accumulates in many tissues. Clinical recognition in males results from characteristic skin lesions (angiokeratomas) over the lower trunk. Patients may show ocular deposits, fe
