Description

Simone Treccarichi leads a 2026 genetics case study of a newly found variant in a gene called RAPGEF6. A variant is a change in a gene's code, and de novo means it appeared new in this person rather than being inherited. The patient had psychiatric disorders and mild intellectual disability. Trio-based whole-exome sequencing, which reads the protein-coding genes of a patient and both parents, found the change.

The variant shifts the reading frame of the gene and was classed as likely disease-causing under standard criteria. Evidence suggests it triggers destruction of the gene's message, so little protein is made. Brain data show the gene is active across the whole lifespan and rises as nerve cells mature in lab tests. The authors argue that having only one working copy contributes to developmental and psychiatric problems.
