Variant chr2-70921151-C-T details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 3P and 2B. PM2PP3BP4_Moderate

The NM_012476.3(VAX2):c.301C>T(p.Arg101Trp) variant causes a missense change. The variant allele was found at a frequency of 0.000162 in 1,612,876 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. R101Q) has been classified as Uncertain significance.

Genes affected

VAX2 (HGNC:12661): (ventral anterior homeobox 2) This gene encodes a homeobox protein and is almost exclusively expressed in the ventral portion of the retina during development. In mouse studies, this gene was found to be required for the correct formation of the optic fissure and other aspects of retinal development. [provided by RefSeq, Sep 2008]

Ambry Genetics

Apr 08, 2022

The c.301C>T (p.R101W) alteration is located in exon 2 (coding exon 2) of the VAX2 gene. This alteration results from a C to T substitution at nucleotide position 301, causing the arginine (R) at amino acid position 101 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
