Abstract :Familial hypercholanemia-2 is a condition caused by mutations in the human solute carrier family 10 member 1 (SLC10A1) gene, which results in the inability to transport conjugated bile salts from plasma to hepatocytes. This is due to the sodium taurocholate cotransport polypeptide encoded by the gene being affected. Although the gene was first described in 1994, there is limited knowledge on the clinical features of the disease. In the few reported cases, both clinical and laboratory findings have varied. We reported a twelve-year-old girl was diagnosed with familial hypercholanemia-2 through a whole gene exome sequencing study. She was brought in with asymptomatic hypertransaminasemia, and after comprehensive studies on etiology failed to detect the cause, genetic testing was done. The patient had no clinically abnormal findings but had hypercholanemia (bile acid level 81.9 μmol/L) (fasting < 10 μmol/L, postprandial < 15 μmol/L) and hypertransaminasemia in laboratory examinations. It is believed that the disease can present with a wide range of phenotypes, and laboratory findings may differ between patients depending on the underlying genetic mutation or mechanisms that have not yet been identified. Therefore, it is recommended to expand diagnostic genetic examinations in patients with hypertransaminasemia whose cause cannot be determinedKeywords : Safra asitleri ve tuzları, Kolestaz, Hiperkolanemi, Sodyum taurokolat birlikte taşınan polipeptit
