One mother had extreme pruritus without jaundice in the last trimester of each of 4 pregnancies, consistent with ICP. Two fathers had reduced maximum excretion of sulfobromophthalein. Treatment with cholestyramine, a bile-salt-sequestering exchange resin, reduced the hyperbilirubinemia. Because the bile showed an increased proportion of dihydroxy bile salts as well as the early onset of changes in the stool and the response to cholestyramine, a defect in bile salt metabolism was postulated. <a href="https://pubmed.ncbi.nlm.nih.gov/?cmd=link&linkname=pubmed_pubmed&from_uid=5762004" target="_blank" onclick="gtag('event', 'mim_outbound', {'name': 'PubMed Related', 'domain': 'pubmed.ncbi.nlm.nih.gov'})"><span class="glyphicon glyphicon-plus-sign mim-tip-hint" title="Click this 'reference-plus' icon to see articles related to this paragraph in PubMed."></span></a></p><p><a href="#20" class="mim-tip-reference" title="Kaye, R. &lt;strong&gt;Comments.&lt;/strong&gt; J.

<p>Progressive familial intrahepatic cholestasis is a heterogeneous group of autosomal recessive liver disorders characterized by early onset of cholestasis that progresses to hepatic fibrosis, cirrhosis, and end-stage liver disease before adulthood (Alonso et al., 1994; Whitington et al., 1994; Klomp et al., 2004). </p><p><strong><em>Genetic Heterogeneity of Progressive Familial Intrahepatic Cholestasis</em></strong></p><p>
PFIC is a genetically heterogeneous disorder caused by defects in the transport of bile acids. See also PFIC2 (601847), caused by mutation in a liver-specific ATP-binding cassette transporter gene (ABCB11; 603201) on chromosome 2q24; PFIC3 (602347), caused by mutation in the class III multidrug resistance P-glycoprotein gene (ABCB4; 171060) on chromosome 7q21; PFIC4 (615878), caused by mutation in the TJP2 gene (607709) on chromosome 9q12; PFIC5 (617049), caused by mutation in the NR1H4 gene (603826) on chromosome 12q23; PFIC6 (619484), caused by mutation in the SLC51A gene (612084) on chromosome 3q29; PFIC7 (619658), caused by mutation in the USP53 gene (617431) on chromosome 4q26; PFIC8 (619662), caused by mutation in the KIF12 gene (611278) on chromosome 9q32; PFIC9 (619849), caused by mutation in the ZFYVE19 gene (619635) on chromosome 15q15; PFIC10 (619868), caused by mutation in the MYO5B gene (606540) on chromosome 18q21; PFIC11 (619874), caused by mutation in the SEMA7A gene (607961) on chromosome 15q24; PFIC12 (620010), caused by mutation in the VPS33B gene (608552) on chromosome 15q26; and PFIC13 (620962) is caused by mutation in the PSKH1 gene (177015) on chromosome 16q22.</p><p>PFIC1 and PFIC2 are associated with mildly elevated or normal serum levels of gamma-glutamyltransferase (GGT; see 612346), whereas PFIC3 is associated with high serum GGT levels and liver histology that shows portal inflammation and ductular proliferation in an early stage (Maggiore et al. (1987, 1991)). PFIC4 is associated with normal or mildly increased GGT levels (Sambrotta et al., 2014). PFIC5 is associated with low to normal GGT levels. PFIC8 and PFIC9 are associated with high GGT levels. </p><p>There are also several phenotypically similar liver disorders that result from congenital defects in bile acid synthesis.

<strong>Clinical Features</strong>
</span>
</h4>
</div>
<span class="mim-text-font">
<p>In the Old Order Amish, Clayton et al. (1965, 1969) described a severe form of intrahepatic cholestasis leading to death in the first decade of life. The main clinical features were early onset of loose, foul-smelling stools, jaundice, hepatosplenomegaly, impaired growth with short stature, and in 4 of 6 cases, death between 17 months and 8 years. One mother had extreme pruritus without jaundice in the last trimester of each of 4 pregnancies, consistent with ICP. Two fathers had reduced maximum excretion of sulfobromophthalein. Treatment with cholestyramine, a bile-salt-sequestering exchange resin, reduced the hyperbilirubinemia. Because the bile showed an increased proportion of dihydroxy bile salts as well as the early onset of changes in the stool and the response to cholestyramine, a defect in bile salt metabolism was postulated. </p><p>Kaye (1965) studied 3 sibs with intrahepatic cholestasis in which itching predated jaundice, which began by 2 or 3 years of age. One sib died at about 7 years of age and 2 were still alive at ages of about 5 and 10. Cholestyramine had no benefit. These patients were later reported by Williams et al. (1972). The same condition was probably described by Gray and Saunders (1966) in 2 sisters who died under 3 years of age and in a patient reported by Hirooka and Ohno (1968). Toussaint and Gros (1966) reported affected brothers. Landing (1972) suggested that hepatoma may be a terminal event in some patients with PFIC. </p><p>De Vos et al. (1975) reported a child with Byler disease. Liver biopsy showed intrahepatic cholestasis, and electron microscopy showed interruptions of the bile canalicular membrane. The findings suggested a primary disturbance in bile acid secretion as the cause of cholestasis. </p><p>Kaplinsky et al. (1980) described a brother and sister with pruritus since infancy who developed cholestatic hepatic cirrhosis early in life. Although the boy had Kayser-Fleischer rings, further studies excluded Wilson disease (277900). Determination of the concentrations and patterns of bile acids in the serum indicated a defect in bile acid transport, not bile acid synthesis. Some of the clinical features resembled those described by Jones et al. (1976). Differences from Byler disease were the absence of steatorrhea and physical retardation and survival beyond puberty in 1 sib. </p><p>Nielsen et al. (1986) described Byler disease in 16 Greenland Eskimo children. Typical features included jaundice, pruritus, malnutrition, steatorrhea, osteodystrophy, short stature, and hyperbilirubinemia. Eight patients had died between the ages of 6 weeks and 3 years. The pedigrees were consistent with autosomal recessive inheritance. Liver biopsy showed nonspecific cholestatic features (Ornvold et al., 1989). </p><p>Whitington et al. (1994) reported 33 patients with PFIC. Symptoms developed almost invariably before 6 months of age with severe pruritus and moderate jaundice. Serum levels of gamma-GGT and cholesterol were not elevated. Twenty-six patients had either partial biliary diversion or orthotopic liver transplantation. Seven patients died at a mean age of 3.9 years from liver failure, hepatocellular carcinoma, or complications of liver transplantation. </p><p>Jacquemin et al. (1994) found that total bile acid concentration was decreased in the bile of 7 children with Byler disease compared to children with other cholestatic diseases. Total bile acid concentration in serum was similar between the 2 groups. Jacquemin et al. (1994) concluded that Byler disease is caused by a defect in primary bile acid secretion. </p><p>In liver biopsies from 28 patients with PFIC and low GGT1 levels, Alonso et al. (1994) found canalicular cholestasis and disruption of the liver cell plate. Giant cell transformation was present in 56% of initial biopsies. Bile duct loss was a prominent and early finding and many biopsies had abnormal bile duct epithelium. Other features included bridging fibrosis, cirrhosis, and pseudoacinar transformation. Mallory hyaline bodies and hepatocellular carcinoma were observed in some patients with advanced cirrhosis. </p><p>Bourke et al. (1996) reported familial cholestasis resembling Byler disease in 8 children in 2 sibships related as first cousins in a highly intermarried group of Irish Travellers, an indigenous Irish nomadic community. The children had a history of neonatal diarrhea, sepsis, and intermittent jaundice that ultimately became permanent. They suffered from intractable pruritus and growth retardation. Despite evidence of severe cholestasis, serum gamma-glutamyltransferase and cholesterol concentrations were normal. Sweat sodium concentrations were raised in 3 children. </p><p>Trauner et al. (1998) reviewed the molecular changes in the hepatocellular transport systems in patients with cholestatic disorders. PFIC1 and PFIC2 were associated with low serum gamma-glutamyltransferase concentrations; the concentration of this enzyme was high in PFIC3. </p><p>Oshima et al. (1999) described 2 sibs with Byler disease and congenital sensorineural hearing loss. </p><p>Klomp et al. (2000) found that liver specimens from 3 Inuit patients with PFIC showed bland canalicular cholestasis. Transmission electron microscopy showed coarsely granular bile similar to that described in Amish patients with the disorder. </p>

<strong>Other Features</strong>

</div>
<span class="mim-text-font">
<p>Nagasaka et al. (2004) reported 2 unrelated patients with PFIC1 and BRIC, respectively, confirmed by the finding of mutations in the ATP8B1 gene. Both patients had short stature, decreased bone mineral density, and episodic hypocalcemia as a result of resistance to parathyroid hormone (PTH; 168450). Detailed biochemical analysis of both patients showed that calcium and phosphorus levels were decreased and increased, respectively, with increasing serum total bilirubin levels. The findings corresponded clinically to pseudohypoparathyroidism type II, in which cAMP response to PTH infusion is normal. </p>

<strong>Mapping</strong>
</span>
</h4>
</div>
<span class="mim-text-font">
<p>By linkage analysis and homozygosity mapping of the extended Amish kindred in which Byler disease was originally described, Carlton et al. (1995) mapped the disease locus, which they symbolized PFIC, to chromosome 18q21-q22. This region was identified by finding shared segments in 2 distantly related Old Order Amish PFIC patients. Carlton et al. (1995) noted that a locus for benign recurrent intrahepatic cholestasis had been mapped to the same region, and suggested that BRIC and PFIC are allelic disorders. Both the clinical and biochemical features of both disorders suggested a defect in primary bile acid secretion. The 19-cM candidate region was located between markers D18S41 and D18S68. </p><p>Eiberg and Nielsen (1993) studied linkage to 45 polymorphic protein markers in Eskimo children from Greenland with Byler disease. Eiberg and Nielsen (2000) demonstrated linkage of Byler disease in Greenland Eskimo children to chromosome 18q between markers D18S851 and D18S858 (multipoint lod score of 3.25). Different haplotypes were associated with the disease gene among Inuits in west Greenland, raising the possibility of locus heterogeneity. </p>

To ensure long-term funding for the OMIM project, we have diversified
our revenue stream. We are determined to keep this website freely
accessible. Unfortunately, it is not free to produce. Expert curators
review the literature and organize it to facilitate your work. Over 90%
of the OMIM's operating expenses go to salary support for MD and PhD
science writers and biocurators. Please join your colleagues by making a
donation now and again in the future. Donations are an important
component of our efforts to ensure long-term funding to provide you the
information that you need at your fingertips.
