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

Sep 16, 2021

The c.55G>A (p.G19S) alteration is located in exon 1 (coding exon 1) of the VAX2 gene. This alteration results from a G to A substitution at nucleotide position 55, causing the glycine (G) at amino acid position 19 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
