摘要: Progressive familial intrahepatic cholestasis (PFIC; OMIM 211600) is the second most common cholestatic syndrome presenting in infancy. A locus has previously been mapped to chromosome 18q21-22 original Byler pedigree. This chromosomal region also harbors for benign recurrent (BRIC) a related phenotype. Linkage analysis six consanguineous PFIC pedigrees from Middle East excluded linkage 18q21-22, indicating existence of heterogeneity within By use homozygosity mapping and genome scan these pedigrees, designated "PFIC2" 2q24. maximum LOD score 8.5 was obtained interval between marker loci D2S306 D2S124, with all families linked.
