Also known as BRIC; FIC1; ICP1; PFIC; ATPIC; PFIC1

Gene ID: 5205 | Gene type: protein coding

About ATP8B1

Cytogenetic location: 18q21.31 Genomic coordinates (GRCh38): 18:57,646,426-57,803,315 (from NCBI)

This gene has 8 transcripts (splice variants), 215 orthologues, 13 paralogues and is associated with 7 phenotypes. Broad expression in colon (RPKM 52.5), stomach (RPKM 26.5) and 17 other tissues.

Summary

This gene encodes a member of the P-type cation transport ATPase family, which belongs to the subfamily of aminophospholipid-transporting ATPases. The aminophospholipid translocases transport phosphatidylserine and phosphatidylethanolamine from one side of a bilayer to another. Mutations in this gene may result in progressive familial intrahepatic cholestasis type 1 and in benign recurrent intrahepatic cholestasis. [provided by RefSeq, Jul 2008]
