Summary
Predicted to enable phenylalanine 4-monooxygenase activity. Acts upstream of or within cellular response to estrogen stimulus. Is expressed in several structures, including digestive system; epidermis; eye; optic vesicle; and periderm. Human ortholog(s) of this gene implicated in intellectual disability and phenylketonuria. Orthologous to human PAH (phenylalanine hydroxylase). [provided by Alliance of Genome Resources, Jun 2025]

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.
