MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a heme enzyme that plays a critical role in tryptophan metabolism by catalyzing the first and rate-limiting step of the kynurenine pathway. Increased activity of the encoded protein and subsequent kynurenine production may also play a role in cancer through the suppression of antitumor immune responses, and single nucleotide polymorphisms in this gene may be associated with autism. [provided by RefSeq, Feb 2012]
PHENOTYPE: Mice homozygous for a knock-out allele exhibit increased plasma and brain levels of tryptophan, increased serotonin levels in the brain, decreased anxiety-related behavior, increased neuronal precursor proliferation and accelerated neurogenesis in the granule cell layer of the olfactory bulb. [provided by MGI curators]
