How single-copy gene activity may drive inherited immune disorders

Monoallelically expressed genes as a novel mechanism of genetic errors of immunity

NIH-funded research Washington University · NIH-11316967

Researchers will look at how some genes that are active from only one inherited copy can change the severity of inherited immune system disorders.

What this research studies

This project studies genes that are sometimes turned on from only one parent's copy instead of both copies and how that affects immune cells. Scientists will analyze genetic and epigenetic marks, study patient-derived blood cells, and perform lab-based cell experiments to map which immune genes show single-copy activity. They will compare samples from people with inherited immune disorders to those without to see if single-copy expression explains why symptoms differ between patients. Results are intended to help clinicians understand variable disease courses and point toward better diagnostics or personalized care.

Who could benefit from this research

Good fit: Ideal participants are people (including children) with known inherited immune disorders or families with unexplained variable immune symptoms who can provide medical history and blood samples.

Not a fit: People without genetic immune conditions or those seeking immediate treatment changes are unlikely to receive direct medical benefit from participation.

Why it matters

Potential benefit: If successful, this work could explain why people with the same mutation have different disease severity and support more precise diagnosis or tailored treatments.

How similar studies have performed: Prior laboratory studies have shown random monoallelic expression exists and can affect gene function, but applying this idea to explain variability in immune genetic diseases is relatively new and exploratory.
