Resumen
Gaucher disease (GD) is a lysosomal storage pathological condition, characterized by a genetic autosomal recessive transmission. The GD cause is the mutation of GBA1 gene, located on the chromosome 1 (1q21), that induces the deficiency of the lysosomal enzyme glucocerebrosidase with consequent abnormal storage of its substrate (glucosylceramide), in macrophages. The GD incidence in the general population varies from 1:40,000 to 1:60,000 live births, but it is higher in the Ashkenazi Jewish ethnicity (1:800 live births). In the literature, five different types of GD are described: type 1, the most common clinical variant in Europe and USA (90%), affects the viscera; type 2, characterized by visceral damage and severe neurological disorders; type 3, in which the neurological manifestations are variable; cardiovascular type; and, finally, perinatal lethal type. The most affected tissues and organs are the hematopoietic system, liver, bone tissue, nervous system, lungs, cardiovascular system and kidneys. Another aspect of GD is represented by oral and dental manifestations. These can be asymptomatic or cause the spontaneous bleeding, the post oral surgery infections and the bone involvement of both arches through the Gaucher cells infiltration into the maxilla and mandibular regions. The pharmacological treatment of choice is the enzyme replacement therapy, but the new pharmacological frontiers are represented by oral substrate reduction therapy, chaperone therapy, allogeneic hematopoietic stem cell transplantation and gene therapy.
