Gaucher disease in children

Classification and early presentation

Gaucher disease is an autosomal recessive lysosomal storage disorder caused by pathogenic variants in the GBA1 gene, resulting in deficient activity of the enzyme acid β glucosidase. This deficiency leads to accumulation of glucosylceramide and related lipids within macrophages, forming characteristic Gaucher cells.^1-5 These lipid laden cells infiltrate multiple organs, particularly the spleen, liver, bone marrow and lungs.^1,2

Why early recognition of Gaucher disease matters

Early recognition in paediatric patients enables timely intervention, preventing irreversible skeletal, hematologic, and visceral complications.^1,2 Various types of treatment are available for patients with Gaucher disease, which focuses on addressing the underlying metabolic defect to reduce disease burden and improve organ function, alongside supportive care for hematologic, skeletal, and growth-related complications. Therapy is individualized based on disease severity, symptoms, and progression, with regular monitoring to guide initiation and adjustment of treatment strategies.¹

Gaucher disease should be considered in children

• frequently presenting with splenomegaly which often emerges before other symptoms and sometimes as the only early sign⁴  
• with hepatomegaly, thrombocytopenia, and anaemia if there is no alternative explanation^2,3
• with bone manifestations, including bone pain, delayed growth, Erlenmeyer-flask deformity, and bone crises^1,4
• with growth delay and delayed puberty²

Clinical types

Gaucher disease comprises three major clinical types ranging from neuronopathic to severe neuronopathic forms, of which type 1 is the most seen form in children (table 1).^3,6-9

Table 1. Clinical types of Gaucher disease^3,6-9

Clinical presentation in children

Children with Gaucher disease almost always (95%) present with splenomegaly, appearing earlier than bone manifestations. In half of young children, splenomegaly is the only initial symptom.^1,4
Hepatomegaly (present in 87% of cases), thrombocytopenia (50%) and anaemia (40%) are among the most common presenting combinations in children with Gaucher disease.^1,2,4

Gaucher disease should be considered when splenomegaly coexists with cytopenias or bone pain.^1,4

Key early symptoms^1,2,3

Age at which symptoms may occur

Symptoms of Gaucher disease can begin in infancy, especially in the more severe forms like Gaucher disease type 2, which often presents prenatally, perinatally, or in the first few months of life, and typically leads to death in infancy. For Gaucher disease type 3, children often show symptoms within the first year and later in childhood, including neurological issues like seizures and saccadic gaze abnormalities. In contrast, GD1 (non-neuronopathic form) tends to have more variable onset, but still typically appears in childhood, with symptoms such as hepatosplenomegaly, thrombocytopenia, anaemia and bone pain. Due to the variability in symptoms and lack of awareness, diagnosis can be significantly delayed. About 1 in 6 patients experienced a delay of ≥7 years or more from the first medical consultation to diagnosis.¹

Differential diagnosis in children

Gaucher disease may be initially mistaken for:

• Hematologic malignancies^1,2
• Immune thrombocytopenia⁴
• Thalassemia⁴
• Other disorders (e.g., ASMD)^1,3
