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]
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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 08, 2022The c.950A>T (p.D317V) alteration is located in exon 15 (coding exon 11) of the NOSTRIN gene. This alteration results from a A to T substitution at nucleotide position 950, causing the aspartic acid (D) at amino acid position 317 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
