Genes affected
NOS2 (HGNC:7873): (nitric oxide synthase 2) Nitric oxide is a reactive free radical which acts as a biologic mediator in several processes, including neurotransmission and antimicrobial and antitumoral activities. This gene encodes a nitric oxide synthase which is expressed in liver and is inducible by a combination of lipopolysaccharide and certain cytokines. Three related pseudogenes are located within the Smith-Magenis syndrome region on chromosome 17. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 21, 2023The c.3140G>A (p.R1047H) alteration is located in exon 25 (coding exon 24) of the NOS2 gene. This alteration results from a G to A substitution at nucleotide position 3140, causing the arginine (R) at amino acid position 1047 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
