Genes affected

NRDC (HGNC:7995): (nardilysin convertase) This gene encodes a zinc-dependent endopeptidase that cleaves peptide substrates at the N-terminus of arginine residues in dibasic moieties and is a member of the peptidase M16 family. This protein interacts with heparin-binding EGF-like growth factor and plays a role in cell migration and proliferation. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, May 2011]

OSBPL9 (HGNC:16386): (oxysterol binding protein like 9) This gene encodes a member of the oxysterol-binding protein (OSBP) family, a group of intracellular lipid receptors. Most members contain an N-terminal pleckstrin homology domain and a highly conserved C-terminal OSBP-like sterol-binding domain, although some members contain only the sterol-binding domain. This family member functions as a cholesterol transfer protein that regulates Golgi structure and function. Multiple transcript variants, most of which encode distinct isoforms, have been identified. Related pseudogenes have been identified on chromosomes 3, 11 and 12. [provided by RefSeq, Jul 2010]

ENSG00000266993 (HGNC:):

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.2716G>A (p.G906S) alteration is located in exon 24 (coding exon 24) of the NRDC gene. This alteration results from a G to A substitution at nucleotide position 2716, causing the glycine (G) at amino acid position 906 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
