Genes affected

NOS3 (HGNC:7876): (nitric oxide synthase 3) Nitric oxide is a reactive free radical which acts as a biologic mediator in several processes, including neurotransmission and antimicrobial and antitumoral activities. Nitric oxide is synthesized from L-arginine by nitric oxide synthases. Variations in this gene are associated with susceptibility to coronary spasm. Alternative splicing and the use of alternative promoters results in multiple transcript variants. [provided by RefSeq, Oct 2016]

The NOS3 c.292C>T variant is predicted to result in the amino acid substitution p.Arg98Cys. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0078% of alleles in individuals of Latino descent in gnomAD (http://gnomad.broadinstitute.org/variant/7-150693513-C-T). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
