Genes affected

UNC5B (HGNC:12568): (unc-5 netrin receptor B) This gene encodes a member of the netrin family of receptors. This particular protein mediates the repulsive effect of netrin-1 and is a vascular netrin receptor. This encoded protein is also in a group of proteins called dependence receptors (DpRs) which are involved in pro- and anti-apoptotic processes. Many DpRs are involved in embryogenesis and in cancer progression. Two alternatively spliced transcript variants have been described for this gene. [provided by RefSeq, Oct 2011]

Ambry Genetics

Mar 06, 2023

The c.23G>C (p.R8P) alteration is located in exon 1 (coding exon 1) of the UNC5B gene. This alteration results from a G to C substitution at nucleotide position 23, causing the arginine (R) at amino acid position 8 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
