Summary

Familial hypercholanemia-1 (FHCA1) is an autosomal recessive disorder characterized by elevated concentrations of bile acids (usually conjugated), itching, and fat malabsorption, leading to poor overall growth and deficiencies of fat-soluble vitamins. Vitamin D deficiency results in rickets, and vitamin K deficiency results in a coagulopathy (Morton et al., 2000; Shneider et al., 1997; summary by Carlton et al., 2003). See also bile acid conjugation defect-1 (BACD1; 619232), which can also show increased bile acid levels, although the bile acids in BACD1 are unconjugated. Genetic Heterogeneity of FHCA See FHCA2 (619256), caused by mutation in the SLC10A1 gene (182396) on chromosome 14q24. [from OMIM]
