Ventral anterior homeobox 1 is a protein that in humans is encoded by the VAX1 gene. [5] [6] [7]

Contents

Function

This gene appears to influence the development in humans of the forebrain. It is also present in mice and xenopus frogs, which suggests a long evolutionary history, and in those organisms its expression is confined to the forebrain, optic and olfactory areas. [8]

VAX1 gene is a transcription factor that has a homeodomain located in the 100-159 amino acid position and an Ala–rich region located in 216-253 amino acid position of the gene. Expression studies in mice show that it is expressed in the palate, coloboma in the visual system, and the basal telencephalon, optic stalk, and visual eye fields where it is expressed along with the Shh and Bmp4 genes. [8] [9] [10]

Clinical significance

Mice with homozygous VAX1 mutations have been reported to display craniofacial malformations including cleft palate. [11]

Genome Wide Association Studies (GWAS) reported significant associations between non-syndromic clefts and SNPs in the VAX1 gene. [12] [13] Replication studies have confirmed these associations in different population groups [14] [15]

Homeobox protein goosecoid(GSC) is a homeobox protein that is encoded in humans by the GSC gene. Like other homeobox proteins, goosecoid functions as a transcription factor involved in morphogenesis. In Xenopus, GSC is thought to play a crucial role in the phenomenon of the Spemann-Mangold organizer. Through lineage tracing and timelapse microscopy, the effects of GSC on neighboring cell fates could be observed. In an experiment that injected cells with GSC and observed the effects of uninjected cells, GSC recruited neighboring uninjected cells in the dorsal blastopore lip of the Xenopus gastrula to form a twinned dorsal axis, suggesting that the goosecoid protein plays a role in the regulation and migration of cells during gastrulation.
