Abstract
BackgroundAutosomal Recessive Polycystic Kidney Disease (ARPKD) is a rare hereditary disorder caused by variants in PKHD1. Currently, aberrant splicing has been reported to play important roles in genetic disease. Our goal is to analyze intronic variants in PKHD1 at the mRNA level.ResultsThe 12 candidate variants were introduced into the corresponding minigene and functionally assayed in HEK 293T and Hela cells. We identified 11 variants that induce splicing alterations, resulting in various consequences such as skipping of exons, intron retention and protein truncation.ConclusionsThis underlined the importance of mRNA-level assessment for genetic diagnostics in related genetic disorders.
