Brief Summary

High-risk screening for Gaucher disease and Acid Sphingomyelinase Deficiency in patients with splenomegaly and/or thrombocytopenia in Taiwan

Detailed Description

Late-onset Gaucher disease (GD) present a unique set of challenges compared to their early-onset counterparts. Symptoms may not appear until adulthood, leading to delayed diagnosis and treatment. This delay can result in irreversible damage to affected tissues and organs, such as the liver, spleen, and central nervous system. Additionally, many late-onset GD are underdiagnosed or misdiagnosed due to their rarity and the variability of symptoms. This study is divided into two phases. In the first phase, patients with hepatosplenomegaly of unknown etiology will be initially screened using an electronic medical record database, and in the second phase, laboratory analysis of biomarkers, including Dry blood spot (DBS) for GBA1 enzyme activity, plasma Lyso-GB1 levels and GBA1 gene sequencing, will be performed. Acid sphingomyelinase deficiency (ASMD) is another lysosomal storage disorder that shares symptoms with GD. Consistent with the above screening strategy for GD patients in two phases (DBS for ASM enzyme activity, plasma Lyso-SM levels and ASM gene sequencing). This study will involve 2,000 candidates from electronic healthcare databases, 240 patients from outpatient clinics, and a cohort of 6 GD1/GD3 patients as controls. In conclusion, initial screening for late-onset GD and ASMD can provide patients with treatment opportunities that can improve outcomes for those affected by these rare diseases.
