Variant 10-71285401-G-A details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 2P and 1B. PM2BP4

The NM_170744.5(UNC5B):c.524G>A(p.Arg175His) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000281 in 1,605,240 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R175L) has been classified as Uncertain significance.

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

Aug 12, 2021

The c.524G>A (p.R175H) alteration is located in exon 4 (coding exon 4) of the UNC5B gene. This alteration results from a G to A substitution at nucleotide position 524, causing the arginine (R) at amino acid position 175 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
