Genetics Test Information Provides information that may help with selection of the correct genetic test or proper submission of the test request

Not available for carrier detection.


Fucosidosis is an autosomal recessive lysosomal storage disorder caused by reduced or absent alpha-L-fucosidase enzyme activity.


For an individual clinically suspicious for an oligosaccharidosis and with a positive screening result (OLIGU / Oligosaccharide Screen, Urine; OLIWB / Oligosaccharidoses Screen, Leukocytes or OLITC / Oligosaccharidoses Screen, Fibroblasts) suggestive of fucosidosis, determining enzymatic activity is the next step of the diagnostic workup.


This test cannot be used to establish carrier status for fucosidosis.
