Gaucher Disease is a rare genetic disorder that affects the body's ability to break down a fatty substance called glucocerebroside. It is an autosomal recessive disorder, meaning that both parents must carry a mutated gene for their child to develop the disease. Gaucher Disease is more prevalent in certain populations, particularly those of Ashkenazi Jewish descent, where the carrier frequency is estimated to be around 1 in 15 individuals.
The overall prevalence of Gaucher Disease varies across different populations. In the general population, it is estimated to affect approximately 1 in 40,000 to 60,000 individuals. However, in specific ethnic groups, such as Ashkenazi Jews, the prevalence is significantly higher, with an estimated incidence of 1 in 450 to 1 in 1,000 individuals.
It is important to note that Gaucher Disease has different types and varying degrees of severity. Type 1, the most common form, typically presents in adulthood and accounts for the majority of cases. Type 2 and Type 3 are less common and usually manifest in infancy or childhood. The prevalence of each type may differ within different populations.
Gaucher Disease, although rare overall, has a higher prevalence in certain ethnic groups, particularly among individuals of Ashkenazi Jewish descent. Genetic testing and counseling are crucial for individuals with a family history of the disease or belonging to at-risk populations to assess their risk and make informed decisions.
