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]

The c.3005A>T (p.H1002L) alteration is located in exon 24 (coding exon 23) of the NOS2 gene. This alteration results from a A to T substitution at nucleotide position 3005, causing the histidine (H) at amino acid position 1002 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
