What this research studies

Children with TANGO2 disorder often experience severe heart rhythm issues that can be life-threatening and don't respond to typical medications. We believe that by understanding the underlying causes of these arrhythmias and how B-vitamins, particularly B9, might prevent or treat them, we can find better solutions. This work will involve studying patients already part of a natural history registry, as well as using special mouse models and human cells grown in the lab. Our goal is to uncover new ways to protect these children's hearts.

Who could benefit from this research

Good fit: Ideal candidates are young children, primarily 0-11 years old, diagnosed with TANGO2 Deficiency Disorder who experience recurring metabolic crises and ventricular arrhythmias.

Not a fit: Patients without TANGO2 Deficiency Disorder or those whose arrhythmias respond well to standard treatments would likely not receive direct benefit from this specific research.

Why it matters

Potential benefit: If successful, this work could lead to new, effective treatments using B-vitamin supplementation to prevent and manage life-threatening heart arrhythmias in children with TANGO2 disorder.

How similar studies have performed: Promising data from an international patient registry and natural history study suggests that B-vitamin supplementation may prevent and treat arrhythmias in TANGO2 disorder.
