What this research studies

You would join a coordinated program that collects your medical history and blood samples to look for genetic and immune causes of NK cell problems. The team uses exome sequencing and other genetic tests and works with an international referral network to find similar patients and candidate genes. Laboratory researchers run functional experiments on patient cells to see how gene changes alter NK cell responses to viruses and cancer. When a genetic cause is identified, the team aims to return results to families and use the findings to guide clinical care and future NK cell–based treatments.

Who could benefit from this research

Good fit: Ideal candidates are people with recurrent or severe viral infections, certain virus-associated cancers, or clinical tests showing abnormal NK cell numbers or function, who are willing to provide medical information and blood samples.

Not a fit: People without NK cell abnormalities or those unwilling/unable to provide samples or travel for evaluation are unlikely to benefit directly from participation.

Why it matters

Potential benefit: If successful, this work could lead to more precise genetic diagnoses, better clinical care plans, and new ways to use NK cells therapeutically.

How similar studies have performed: Similar genomic and functional approaches from this group and others have already discovered new NKD genes and provided diagnoses for affected patients, so this builds on prior successes.
