Congenital hepatic fibrosis caused by PKHD1 gene mutation:a case report and literature review
Objective To explore the clinical features,pathological features,gene mutation loci and diagnosis and treatment of congenital hepatic fibrosis(CHF)caused by polycystic kidney and hepatic disease 1(PKHD1)gene mutation,in order to provide reference for clinical diagnosis and treatment of this disease.Methods The clinical course of 1 patient with CHF caused by PKHD1 gene mutation was retrospectively analyzed,and the related literature was reviewed.Results The patient started with acute upper gastrointestinal bleeding and was diagnosed as CHF by imaging,histology,and genetic examination.Genetic examination revealed double heterozygous mutations in PKHD1 gene(c.7445G>A and c.7769T>G).After endoscopic,interventional and drug treatment,the patient's condition improved and was discharged from the hospital.No recurrence was found in the follow-up to 1 year after the onset of the disease.Conclusion CHF is rare and easy to be misdiagnosed or missed.The diagnosis is mainly based on histopathological morphology.When patients have gastrointestinal bleeding and normal or mildly abnormal liver function,the possibility of CHF caused by PKHD1 gene should be considered.Genetic testing technology can help in the early diagnosis of this disease.
