Understanding why some genetic diseases show different symptoms in different people

Identifying sources of variable penetrance and expressivity in monogenic diseases at population scale

NIH-funded research University of California Los Angeles · NIH-11060176

This study is looking into why people with the same genetic changes can have different symptoms or sometimes none at all, and it’s for anyone interested in understanding how these differences can affect conditions caused by single gene mutations.

What this research studies

This research investigates why individuals with the same genetic mutations may experience varying symptoms or none at all. By analyzing genetic data from diverse populations, the study aims to identify factors that influence the severity and presence of symptoms in monogenic diseases. The researchers will collaborate with multiple biobanks to gather extensive data, focusing on how common genetic variants interact with specific mutations. This approach could lead to a better understanding of disease mechanisms and improve patient care.

Who could benefit from this research

Good fit: Ideal candidates for this research include individuals with known monogenic variants, especially those who have experienced mild or no symptoms.

Not a fit: Patients with complex polygenic diseases or those without identifiable monogenic variants may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to more accurate predictions of disease severity and tailored treatment options for patients with monogenic diseases.

How similar studies have performed: Previous research has shown promising results in understanding genetic variants and their effects on disease expression, indicating that this approach has potential for success.
