Background: Gaucher disease (GD) is an autosomal recessive lysosomal storage disease. The disease develops due to glucocerebrosidase enzyme deficiency caused by biallelic pathogenic variants in the glucosylceramidase beta 1 (GBA1) gene, which encodes the glucocerebrosidase enzyme. The GBA1 gene is located at chromosomal location 1q22 and consists of 11 exons. In this article, we report a novel pathogenic variant in the GBA1 gene. Case Presentations: A 32-year-old female patient with no known chronic disease was admitted with complaints of weakness, bone pain, and abdominal pain. Her evaluation included hepatosplenomegaly, thrombocytopenia, osteoporosis, and anemia. The clinical suspicion of Gaucher disease was confirmed by glucocerebrosidase enzyme level and genetic testing. In her family screening, her sister also had hepato-splenomegaly, osteoporosis, thrombocytopenia, and anemia. Both sisters had no neurological symptoms. As a result of GBA1 gene sequence analysis in two of our patients, a missense variant was detected in the c.593C > A homozygous genotype. This variant has not been reported in any previously published case. Conclusion: In this case report, we aimed to contribute to the literature by reporting a new novel pathogenic variant in the GBA1 gene leading to type 1 Gaucher disease that has not been described before.
