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]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -12 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.007729441).
BS1
Variant frequency is greater than expected in population eas. gnomad4_exome allele frequency = 0.000613 (896/1461462) while in subpopulation EAS AF= 0.0212 (841/39694). AF 95% confidence interval is 0.02. There are 8 homozygotes in gnomad4_exome. There are 428 alleles in male gnomad4_exome subpopulation. Median coverage is 30. This position pass quality control queck.
BS2
High Homozygotes in GnomAdExome4 at 8 gene
