Understanding how genetic changes lead to limb malformations

Official title: Deciphering Mechanisms of Limb Malformations Caused by Noncoding Variants In Vivo

Funded at University of California-Irvine · NIH-11001088 · Data updated 2026-11-12

This study is looking into how certain genetic changes can lead to limb malformations, which are common birth defects, to help us understand why they happen and how they affect limb development.

Who could benefit from this research

Could help

Ideal candidates for this research include individuals with non-syndromic limb malformations, particularly those with a family history of such conditions.

Less likely to help

Patients with limb malformations caused by known syndromic conditions or other non-genetic factors may not benefit from this research.

What this research studies

This research investigates the genetic factors that contribute to limb malformations, which are among the most common congenital abnormalities. By focusing on rare noncoding mutations that affect transcriptional enhancers, the study aims to uncover how these genetic changes lead to abnormal limb development. The researchers will utilize in vivo models to better understand the mechanisms behind these mutations and their effects on gene expression. This approach is crucial for identifying the specific conditions under which these genetic variants cause limb defects.

Why it matters

Potential benefit: If successful, this research could lead to improved understanding and potential interventions for congenital limb malformations.

How similar studies have gone: Previous research has shown promise in understanding genetic contributions to congenital malformations, but this specific approach focusing on noncoding variants is relatively novel.
