An instance of restrictive cardiomyopathy that is caused by an inherited modification of the individual's genome.
No HPO annotations are available for this condition.
Age of onset: before birth, infancy, childhood.
Gaucher disease (GD) encompasses a spectrum of clinical findings from a perinatal-lethal form to an asymptomatic form. However, for the purposes of determining prognosis and management, the classification of GD by clinical type is still useful in describing the wide range of clinical findings and broad variability in presentation. Three major clinical types are delineated by the absence (type 1) or presence (types 2 and 3) of primary central nervous system (CNS) involvement .
Suggestive Findings Scenario 1: Abnormal Newborn Screening (NBS) Result NBS for Gaucher disease (GD) is primarily based on quantification of glucocerebrosidase enzyme activity on dried blood spots. Glucocerebrosidase enzyme activity values below the cutoff reported by the screening laboratory are considered positive, and additional testing is required to establish the diagnosis . Scenario 2: Symptomatic Individual GD encompasses a continuum of clinical findings from a perinatal-lethal disorder to type 1 GD with adult onset. GD should be suspected in individuals (by age) with the following combination of central nervous system, bony, hematologic, and other clinical and family history findings . Table 1. Gaucher Disease: Clinical Phenotypes
No approved treatments are currently available for familial restrictive cardiomyopathy. The disease remains an area of unmet medical need.
Clinical management guidelines for Gaucher disease (GD) have been published . Management by a multidisciplinary team with expertise in treating GD is available at Comprehensive Treatment Centers (see National Gaucher Foundation).
To establish the extent of disease and needs in an individual diagnosed with GD, the evaluations summarized in or (if not performed as part of the evaluation that led to the diagnosis) are recommended. Recommended evaluations following initial diagnosis can vary based on age at diagnosis, mode of ascertainment (e.g., asymptomatic vs symptomatic individual), and presence or absence of primary neurologic involvement. Baseline (pre-treatment) assessments may be useful in selecting treatment modality and regimen (e.g., enzyme dose, frequency of infusion).
Physicians who are the US regional coordinators for the International Collaborative Gaucher Group Registry (ICGG) and other groups have published recommendations for comprehensive serial monitoring of the severity and rate of disease progression [, , , ]. A European working group has also published a consensus document relating to management goals for individuals with type 1 GD . To monitor existing manifestations, the individual's response to supportive care, and the emergence of new manifestations, the evaluations summarized in are recommended.
7 clinical trials registered, 3 recruiting. Interventions under study include other interventions and drug therapy. Pipeline includes 1 NA. Research is sponsored by a mix of industry and academic institutions.

Findings in Gaucher disease (GD) may overlap with some lysosomal storage diseases ; however, the distinctive clinical features associated with these lysosomal storage disorders, biochemical testing, and an understanding of their natural history should help distinguish between them.

Nonsteroidal anti-inflammatory drugs should be avoided in individuals with moderate-to-severe thrombocytopenia. The use of anticoagulants in individuals with severe thrombocytopenia and/or coagulopathy should be discussed with a hematologist to avoid the possibility of excessive bleeding.

Substrate reduction therapy. Venglustat, an investigational, brain-penetrant glucosylceramide synthase inhibitor, has been administered to adults with type 3 GD receiving imiglucerase. In an early phase clinical trial, addition of once-daily venglustat showed acceptable safety and tolerability and preliminary evidence of clinical stability but inconsistent changes in selected biomarkers . These findings need to be validated and confirmed in future research. Chaperone-mediated enzyme enhancement therapy. Pharmacologic chaperones (PCs), competitive reversible active site inhibitors, serve as a folding template for the defective enzyme during its transit to the endoplasmic reticulum. Such agents may restore enzyme activity within the lysosome and clear stored substrate.
