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]

ACMG classification

Verdict is Benign. Variant got -8 ACMG points.

• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.015 (981/65262) while in subpopulation AFR AF= 0.0519 (918/17680). AF 95% confidence interval is 0.0491. There are 23 homozygotes in gnomad4. There are 495 alleles in male gnomad4 subpopulation. Median coverage is 0. This position pass quality control queck.
• BS2: High AC in GnomAd4 at 981 AD gene.
