Genes affected

NOSTRIN (HGNC:20203): (nitric oxide synthase trafficking) Nitric oxide (NO) is a potent mediator in biologic processes such as neurotransmission, inflammatory response, and vascular homeostasis. NOSTRIN binds the enzyme responsible for NO production, endothelial NO synthase (ENOS; MIM 163729), and triggers the translocation of ENOS from the plasma membrane to vesicle-like subcellular structures, thereby attenuating ENOS-dependent NO production.[supplied by OMIM, Apr 2004]

NOSTRIN links:

SPC25 (HGNC:24031): (SPC25 component of NDC80 kinetochore complex) This gene encodes a protein that may be involved in kinetochore-microtubule interaction and spindle checkpoint activity. [provided by RefSeq, Jul 2008]

Mar 29, 2024

The c.1118C>A (p.A373D) alteration is located in exon 16 (coding exon 12) of the NOSTRIN gene. This alteration results from a C to A substitution at nucleotide position 1118, causing the alanine (A) at amino acid position 373 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
