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.364G>C (p.V122L) alteration is located in exon 6 (coding exon 4) of the NOSIP gene. This alteration results from a G to C substitution at nucleotide position 364, causing the valine (V) at amino acid position 122 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
