Arthrogryposis, renal dysfunction, and cholestasis 1

Arthrogryposis, renal dysfunction, and cholestasis-1 (ARCS1) is characterized by congenital joint contractures, renal tubular dysfunction, cholestasis with low GGT (612346) activity, severe failure to thrive, ichthyosis, and a defect in platelet alpha-granule biogenesis. Most patients with ARC do not survive past the first year of life (Gissen et al., 2006; Smith et al., 2012). Another form of arthrogryposis, renal dysfunction, and cholestasis, ARCS2 (613404), is caused by mutation in the VIPAR gene on chromosome 14q24 (613401). [from OMIM]

Congenital bile acid synthesis defect 1

Congenital defects of bile acid synthesis are autosomal recessive disorders characterized by neonatal onset of progressive liver disease with cholestatic jaundice and malabsorption of lipids and lipid-soluble vitamins from the gastrointestinal tract resulting from a primary failure to synthesize bile acids. Affected infants show failure to thrive and secondary coagulopathy. In most forms of the disorder, there is a favorable response to oral bile acid therapy (summary by Cheng et al., 2003). Genetic Heterogeneity of Congenital Defects in Bile Acid Synthesis There are several disorders that result from defects in bile acid synthesis. See CBAS2 (235555), caused by mutation in the delta(4)-3-oxosteroid 5-beta-reductase gene (AKR1D1; 604741) on chromosome 7q33; CBAS3 (613812), caused by mutation in the 7-alpha hydroxylase gene (CYP7B1; 603711) on chromosome 8q12; CBAS4 (214950), caused by mutation in the AMACR gene (604489) on chromosome 5p13; CBAS5 (616278), caused by mutation in the ABCD3 gene (170995) on chromosome 1p21; and CBAS6 (617308), caused by mutation in the ACOX2 gene (601641) on chromosome 3p14. See also progressive familial intrahepatic cholestasis (PFIC1; 211600), which has a similar phenotype. [from OMIM]

Arthrogryposis, renal dysfunction, and cholestasis 2

Arthrogryposis, renal dysfunction, and cholestasis-2 (ARCS2) is a multisystem disorder associated with abnormalities in polarized liver and kidney cells (Qiu et al., 2019). For a general phenotypic description and a discussion of genetic heterogeneity of ARCS, see ARCS1 (208085). [from OMIM]
