Omics Gaucher Study: Multiomic Approach

Gaucher disease is one of the most common lysosomal storage disorders (LSD) and is an autosomal recessive inherited disorder, primed by mutation in the GBA1 gene which leads to a deficiency in β-glucocerebrosidase (GCase) activity and accumulation of its substrate glucosylceramide (GluCer)/-sphingosine (GluSph). The macrophages are the main cell type exhibiting a Gaucher disease phenotype. The large accumulation of GluCer and to a lesser extent that of GluSph lead to dysfunction in organs such as spleen, liver, bone marrow, and lungs.

However, a validated, reproducible, and broadly applicable tool to classify Gaucher Disease at any stage of the disease is still missing.

The development of new technologies, such as genomic analysis by next generation sequencing (NGS) and other "omics technologies," has advanced the molecular understanding and diagnosis of Rare Diseases

The current study will analyze the transcriptional and metabolomic profiles in blood, plasma and isolated monocytes from Gaucher patients and healthy controls with the aim to compare these profiles and to define how much a patient profile differs from a healthy one.
