AI Article Synopsis
Article Abstract
In this case report, we present the bone scintigraphic findings of a 9-year-old boy with Gaucher disease who has a history of fractures to evaluate the extent of his osseous lesions. Gaucher disease is a genetic deficiency of lysosomal enzyme glucocerebrosidase, which results in the accumulation of glucocerebroside in the macrophages in the reticuloendothelial cells of the spleen, liver, and bone marrow. Most patients with type 1 Gaucher disease present a clinical or radiographic evidence of infiltrative bone disease. Lipid-filled macrophages called Gaucher cells infiltrate the bone marrow, leading to medullary expansion, diffuse osteoporosis, ischemic necrosis, and fractures.

Gaucher disease is a rare lysosomal storage disorder characterized by the accumulation of glucocerebroside lipids within multiple organs due to a deficiency of the lysosomal enzyme (acid β-glucosidase). It is an inherited autosomal recessive disease. The onset of symptoms can vary depending on disease type and severity, with milder forms presenting in adulthood.

Introduction: Gaucher disease (GD) is a lysosomal storage disorder causing systemic and skeletal complications. This study evaluates bone health in adult GD type 1 patients, focusing on skeletal complications, bone mineral density (BMD), and biochemical markers.
Material And Methods: A cohort of adult GD type 1 patients followed up at Ege University Pediatric Metabolism Department were retrospectively examined.

There are currently at least 70 characterised lysosomal storage diseases (LSD) resultant from inherited single-gene defects. Of these, at least 30 present with central nervous system (CNS) neurodegeneration and overlapping aetiology. Substrate accumulation and dysfunctional neuronal lysosomes are common denominator, but how variants in 30 different genes converge on this central cellular phenotype is unclear.

Gaucher disease (GD) is a rare lysosomal disorder characterized by the accumulation of glycosphingolipids in macrophages resulting from glucocerebrosidase (GCase) deficiency. The accumulation of toxic substrates, which causes the hallmark symptoms of GD, is dependent on the extent of enzyme dysfunction. Accordingly, three distinct subtypes have been recognized, with type 1 GD (GD1) as the common and milder form, while types 2 (GD2) and 3 (GD3) are categorized as neuronopathic and severe.
