KIF12 Variants and Disturbed Hepatocyte Polarity in Children with a Phenotypic Spectrum of Cholestatic Liver Disease

KIF12 has been identified as a cholestasis-associated candidate gene. We describe 6 cases from 4 unrelated families with diverse cholestatic phenotypes carrying 2 different homozygous KIF12 truncating variants. Immunofluorescence investigations of paraffin-embedded liver sections suggest that KIF12-associated impaired functional cell polarity may be the underlying cause.

This study identified 6 cases from 4 unrelated families with diverse cholestatic phenotypes carrying 2 different homozygous KIF12 truncating variants. Immunofluorescence investigations of paraffin-embedded liver sections suggest that impaired functional cell polarity associated with KIF12 may be the underlying cause.
