PKHD1 and Hepatic fibrosis: Comparing peaks from multiple tissues in that region, there are also several liver-specific regulatory peaks within intron 59 of PKHD1 (Ensembl Transcript ID: ENSECAT00000024985.1) that may affect expression of this or another hepatic gene nearby (Figure 4) and represent another avenue to explore for the molecular mechanism underlying liver fibrosis.
