Lysosomes are cytoplasmic organelles that contain a variety of different
hydrolases. A genetic deficiency in the enzymatic activity of one of these
hydrolases will lead to the accumulation of the material meant for lysosomal
degradation. Examples include glycogen in the case of Pompe disease,
glycosaminoglycans in the case of the mucopolysaccharidoses, glycoproteins in the
cases of the oligosaccharidoses, and sphingolipids in the cases of Niemann-Pick
disease types A and B, Gaucher disease, Tay-Sachs disease, Krabbe disease, and
metachromatic leukodystrophy. Sometimes, the lysosomal storage can be caused not
by the enzymatic deficiency of one of the hydrolases, but by the deficiency of an
activator protein, as occurs in the AB variant of GM2 gangliosidosis. Still other
times, the accumulated lysosomal material results from failed egress of a small
molecule as a consequence of a deficient transporter, as in cystinosis or Salla
disease. In the last couple of decades, enzyme replacement therapy has become
available for a number of lysosomal storage diseases. Examples include
imiglucerase, taliglucerase and velaglucerase for Gaucher disease, laronidase for
Hurler disease, idursulfase for Hunter disease, elosulfase for Morquio disease,
galsulfase for Maroteaux-Lamy disease, alglucosidase alfa for Pompe disease, and
agalsidase alfa and beta for Fabry disease. In addition, substrate reduction
therapy has been approved for certain disorders, such as eliglustat for Gaucher
disease. The advent of treatment options for some of these disorders has led to
newborn screening pilot studies, and ultimately to the addition of Pompe disease
and Hurler disease to the Recommended Uniform Screening Panel (RUSP) in 2015 and
2016, respectively.
