Variant 7-150996515-C-T details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Benign. Variant got -8 ACMG points: 0P and 8B. BP4_StrongBS2

The NM_000603.5(NOS3):c.382C>T(p.Arg128Trp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000144 in 1,607,330 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R128Q) has been classified as Benign.

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]

Ambry Genetics

Oct 26, 2021

The c.382C>T (p.R128W) alteration is located in exon 4 (coding exon 3) of the NOS3 gene. This alteration results from a C to T substitution at nucleotide position 382, causing the arginine (R) at amino acid position 128 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
