Genes affected

NOSIP (HGNC:17946): (nitric oxide synthase interacting protein) The protein encoded by this gene may modulate the activity and localization of nitric oxide synthase (endothelial and neuronal) and thus nitric oxide production. Alternative splicing results in multiple transcript variants that encode the same protein. [provided by RefSeq, Aug 2012]

The c.298A>G (p.K100E) alteration is located in exon 6 (coding exon 4) of the NOSIP gene. This alteration results from a A to G substitution at nucleotide position 298, causing the lysine (K) at amino acid position 100 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
