    Summary
    Predicted to enable tryptophan 5-monooxygenase activity. Involved in several processes, including cellular response to lithium ion; response to activity; and response to estrogen. Predicted to be active in neuron projection. Human ortholog(s) of this gene implicated in autistic disorder; major depressive disorder; and panic disorder. Orthologous to human TPH2 (tryptophan hydroxylase 2). [provided by Alliance of Genome Resources, Dec 2024]

    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.
