Hereditary stomatocytosis

Hereditary stomatocytosis is a rare, genetic, hematologic disorder characterized by the presence of stomatocytes (red blood cells with a mouth-like shape) on peripheral blood smears, and associated with hemolytic anemia of variable severity.

Clinical Description[edit | edit source]

Hereditary stomatocytosis is a condition that affects red blood cells (RBCs), which carry oxygen from the lungs to the rest of the body. In most cases, this condition is characterized by hemolytic anemia. Hemolysis can lead to jaundice, and splenomegaly can occur. The condition is present from birth, and symptoms can range from mild to severe.

Genetics[edit | edit source]

Hereditary stomatocytosis is caused by mutations in the PIEZO1 gene. It is inherited in an autosomal dominant manner. This means that an individual only needs one copy of the altered gene for the condition to occur.

Diagnosis[edit | edit source]

Diagnosis of hereditary stomatocytosis is based on the clinical findings, a complete blood count, a family history, and specialized laboratory testing. Molecular genetic testing can confirm the diagnosis.

Management and Treatment[edit | edit source]

Treatment of hereditary stomatocytosis is focused on managing the symptoms and complications. This can include regular blood transfusions and, in some cases, removal of the spleen (splenectomy).

Prognosis[edit | edit source]

The long-term outlook for people with hereditary stomatocytosis varies. Some people may have mild symptoms or no symptoms, and others may have severe symptoms. It is important for people with this condition to have regular follow-up appointments with their healthcare provider.
