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]

The c.436G>A (p.V146I) alteration is located in exon 3 (coding exon 3) of the UNC5B gene. This alteration results from a G to A substitution at nucleotide position 436, causing the valine (V) at amino acid position 146 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
