    1. We then amassed convergent genomic evidence showing population level associations between LDAHexpression and occurrence of prostate cancer . We further identified loss of LDAH in both tissues and cell lines derived from human prostate cancer, and generated Ldah-/- mouse model, which recapitulated many of the clinical findings in DGAP056.

    RefSeqs maintained independently of Annotated Genomes

    These reference sequences exist independently of genome builds. Explain

    These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
