Ferrochelatase Gene Variants Associated with Cholestasis in Adults: A Case Report.

Abstract

We reported a case of recurrent liver dysfunction in an adult patient with a history of abnormal liver enzymes persisting for over ten years. The primary abnormalities included elevated levels of gamma-glutamyl transferase and alkaline phosphatase. Despite conducting a series of extensive etiological tests to identify common causes of liver disease, the diagnosis remained unclear. However, whole-exome next-generation sequencing revealed a homozygous intronic mutation in the ferrochelatase gene (c.315-48T>C), which may be associated with the patient's cholestasis.
