Mutations in this gene cause the X-linked Kallmann syndrome. The encoded protein is similar in sequence to proteins known to function in neural cell adhesion and axonal migration. In addition, this cell surface protein is N-glycosylated and may have anti-protease activity.ANOS1 (Anosmin 1) is a Protein Coding gene. Diseases associated with ANOS1 include Hypogonadotropic Hypogonadism 1 With Or Without Anosmia and Kallmann Syndrome. Among its related pathways are Negative regulation of FGFR1 signaling and Signaling by FGFR2. GO annotations related to this gene include heparin binding and extracellular matrix structural constituent.
