| 520 | _aBACKGROUND: The nitric oxide (NO) signaling pathway in hypothalamic neurons plays a key role in the regulation of the secretion of gonadotropin-releasing hormone (GnRH), crucial for reproduction. We hypothesized that a disruption of neuronal NO synthase (NOS1) activity underlies some forms of hypogonadotropic hypogonadism. METHODS: Whole exome sequencing was performed on a large cohort of probands with congenital hypogonadotropic hypogonadism to identify ultra-rare variants in NOS1. The activity of NOS1 mutants identified was assessed by their ability to promote nitrite and cGMP production in vitro. In addition, physiological and pharmacological characterization was carried out in a Nos1-deficient mouse model. FINDINGS: We identified 5 heterozygous NOS1 loss-of-function mutations in 6 probands with congenital hypogonadotropic hypogonadism (2%), who displayed additional phenotypes including anosmia, hearing loss and intellectual disability. In addition, NOS1 was found to be transiently expressed by newly born GnRH neurons in the nose of both humans and mice, and Nos1 deficiency in mice resulted in dose-dependent defects not only in sexual maturation but also olfaction, hearing and cognition. The pharmacological inhibition of NO production in infantile mice revealed a critical time window during which Nos1 activity shaped minipuberty and sexual maturation. Inhaled NO treatment at minipuberty rescued both reproductive and behavioral phenotypes in Nos1-deficient mice. INTERPRETATION: The lack of timely NOS1 activity causes GnRH deficiency and lifelong sensory and intellectual comorbidities in humans and mice. NO treatment during a critical window, by reversing deficits in sexual maturation, olfaction and cognition in Nos1-deficient mice, thus holds therapeutic potential for humans. | ||
