lysosomal storage diseases (lsds) result from a genetic defect in synthesis and cellular transport of lysosomal enzyme to the lysosomes. lsds are progressive and may present at any age affecting multiple tissues and organ systems. they comprise a diverse group of over 40 clinically distinct inherited disorders. as a group they occur in approximately 1 in 5000 to 8000 births in the western socie...

Lysosomal storage diseases (LSDs) are a family of disorders that result from inherited gene mutations that perturb lysosomal homeostasis. LSDs mainly stem from deficiencies in lysosomal enzymes, but also in some non-enzymatic lysosomal proteins, which lead to abnormal storage of macromolecular substrates. Valuable insights into lysosome functions have emerged from research into these diseases. ...

Autophagy is a complex pathway regulated by numerous signaling events that recycles macromolecules and can be perturbed in lysosomal storage diseases (LSDs). The concept of LSDs, which are characterized by aberrant, excessive storage of cellular material in lysosomes, developed following the discovery of an enzyme deficiency as the cause of Pompe disease in 1963. Great strides have since been m...

157 in the delivery room, and the normal newborn with a number of very pertinent sections about the situations in which the neonate finds himself in most serious trouble. The chapter on assessment of gestational age, for example, has both pictures and charts which will allow the physician to compare the physical examination in the patient with established standards. Pictures are of excellent qu...

Biochemical disorders in lysosomal storage diseases consist of the interruption of metabolic pathways involved in the recycling of the degradation products of one or several types of macromolecules. The progressive accumulation of these primary storage products is the direct consequence of the genetic defect and represents the initial pathogenic event. Downstream consequences for the affected c...
