    Distinct expression requirements and rescue strategies for BEST1 loss- and gain-of-function mutations

    Qingqing Zhao, Yang Kong ... Tingting Yang
    BEST1 autosomal dominant loss-of-function mutations surprisingly behave in a dominant-negative manner, whereas gain-of-function mutations exhibit a strong dominant effect that necessitates CRISPR/Cas9-mediated suppression of the endogenous mutant allele in gene therapy.
