Summary

Familial hypercholanemia-3 (FHCA3) is an autosomal recessive metabolic disorder characterized by onset of symptoms, including jaundice and failure to thrive, in early infancy. The clinical features of the disorder result from impaired absorption of fat-soluble vitamins. Vitamin D deficiency causes rickets with variable growth deficiency, and vitamin K deficiency causes a coagulopathy with decreased production of vitamin K-dependent clotting factors. More variable features may include pruritis, anemia, hepatomegaly, and bile duct proliferation on liver biopsy. Laboratory studies show abnormally increased levels of unconjugated bile acids (summary by Setchell et al., 2013). For a discussion of genetic heterogeneity of FHCA, see FHCA1 (607748). [from OMIM]
