Fabry disease (FD) is a rare X-linked recessive genetic disorder caused by a
deficient activity of the lysosomal enzyme alpha-galactosidase A (GLA) and is
characterised by intra-lysosomal accumulation of globotriaosylceramide (Gb3). We
performed a meta-analysis of peer-reviewed publications including high-throughput
omics technologies including naïve patients and those undergoing enzyme
replacement therapy (ERT). This study describes FD on a systems level using a
systems biology approach, in which molecular data sourced from multi-omics
studies is extracted from the literature and integrated as a whole in order to
reveal the biochemical processes and molecular pathways potentially affected by
the dysregulation of differentially expressed molecules. In this way new insights
are provided that describe the pathophysiology of this rare disease. Using gene
ontology and pathway term clustering, FD displays the involvement of major
biological processes such as the acute inflammatory response, regulation of wound
healing, extracellular matrix (ECM) remodelling, regulation of peptidase
activity, and cellular response to reactive oxygen species (ROS). Differential
expression of acute-phase response proteins in the groups of naïve (up-regulation
of ORM1, ORM2, ITIH4, SERPINA3 and FGA) and ERT (down-regulation of FGA, ORM1 and
ORM2) patients could be potential hallmarks for distinction of these two patient
groups.
