Discovering genes that influence facial and jaw shape

Discovery and functional analysis of novel candidate genes and variants underlying craniofacial diversification in Cyprinodon pupfishes

NIH-funded research University of California Berkeley · NIH-11059074

What this research studies

You'd hear that researchers use Caribbean pupfish, which naturally show many different face and jaw shapes, to look for genes that control facial development. They compare genomes across wild and lab populations and use genomic mapping and CRISPR gene editing in fish to test which candidate genes or DNA changes cause shape differences. Because many of the basic face-building genes are similar across vertebrates, the team hopes findings will point to genes that matter in human craniofacial birth defects. The work involves lab breeding, detailed skull measurements, DNA sequencing, and experiments that change fish genes to see physical effects.

Who could benefit from this research

Good fit: People born with craniofacial differences (for example cleft lip or palate and other jaw or facial malformations) who are interested in genetic research might follow or benefit from this work.

Not a fit: Patients needing immediate clinical care or surgical correction should not expect direct or immediate treatment benefits from this lab-based fish genetics work.

Why it matters

Potential benefit: Could identify new genes and variants that explain human craniofacial birth defects and point toward improved diagnosis or future therapies.

How similar studies have performed: Related studies using zebrafish and other animal models have successfully linked genes to craniofacial development, but using Caribbean pupfish to find new human-relevant variants is relatively novel.
