Liver enlargement could be a warning sign of this rare genetic condition: What to know about Gaucher disease

Gaucher is a rare genetic condition that causes fatty substance build up in the tissues of spleen, liver and bones and ultimately causes damage and dysfunction of tissues and organs."Nearly 1 in 100 people globally may carry a mutation in the GBA gene, which causes Gaucher Disease, yet many affected patients remain undiagnosed for years because the symptoms often resemble common blood or liver disorders," says Dr Furqan Khan, Consultant Neurologist at Saifee Hospital.

Adding to this, Dr Sachin Adukia, Senior Consultant Neurologist, Dr. L. H. Hiranandani Hospital, Powai told TOI Health, "in the expanding world of genetic medicine, some conditions remain surprisingly unfamiliar outside specialist circles.

Gaucher disease, the most common lysosomal storage disorder worldwide, is one such example." "From a general medicine perspective, Gaucher disease is caused by deficiency of the enzyme glucocerebrosidase. This leads to accumulation of fatty substances within cells of the liver, spleen and bone marrow. Research published in the Journal of the American Medical Association describes Gaucher disease as a disorder in which lipid-laden macrophages infiltrate multiple organs, producing systemic symptoms," Dr.

Sachin added."For neurologists, Gaucher disease has gained attention for another reason. Research published in The New England Journal of Medicine demonstrated that mutations in the GBA gene, responsible for Gaucher disease, represent one of the most important genetic risk factors for Parkinson’s disease. This discovery has reshaped scientific thinking about neurodegeneration. Even carriers of the mutation, people who do not have Gaucher disease themselves, may have a higher risk of Parkinsonian symptoms later in life," he added.

Gaucher disease hides in plain sight

"One of the reasons Gaucher disease often goes unrecognized is that its symptoms can mimic more common conditions. Patients may present with enlarged liver or spleen, anemia, low platelet counts, bone pain, recurrent fractures, and fatigue as common symptoms. In children, it may manifest as growth delay or unexplained abdominal swelling. Because these symptoms are nonspecific, patients may remain undiagnosed for years," says Dr.

Furqan Khan. "In India, awareness among clinicians and the public is still evolving. Because Gaucher disease is genetic and inherited in an autosomal recessive pattern, genetic counseling and family screening are essential once a case is diagnosed."

Early diagnosis is crucial

There are three main types of Gaucher disease Type 1 (Non-neuronopathic): Most common; primarily affects spleen, liver, and bones. Type 2 (Acute neuronopathic): Severe form affecting infants with rapid neurological decline and Type 3 (Chronic neuronopathic): Progressive neurological involvement with systemic disease.

More than 90% of the cases are Type 1, MayoClinic says."Early diagnosis is important because effective treatments are available, including enzyme replacement therapy (ERT) and substrate reduction therapy (SRT). These therapies can significantly improve quality of life, reduce organ enlargement, improve blood counts, and prevent long-term complications if started early," Dr. Furqan Khan says.Medical experts consulted This article includes expert inputs shared with TOI Health by: Dr Sachin Adukia, Senior Consultant Neurologist, Dr. L.
