Daniel Quiat

M.D., Ph.D.

Attending, Department of Cardiology, Boston Children’s Hospital

Instructor in Pediatrics, Harvard Medical School

Dr. Daniel Quiat is a pediatric cardiologist at Boston Children’s Hospital and an Instructor of Pediatrics at Harvard Medical School. Dr. Quiat earned his MD and PhD in 2014 from the Medical Science Training Program (MSTP) at University of Texas Southwestern Medical Center. Dr. Quiat then completed both his residency and fellowship at Boston Children’s Hospital, where he is board certified in pediatrics and pediatric cardiology with specialties in pediatric cardiomyopathies and congenital heart defects. In addition to his clinical responsibilities, Dr. Quiat pursues biomedical research in cardiovascular development and genetics in collaboration with the Seidman Lab at Harvard Medical School Department of Genetics, with a goal of identifying genetic causes of single ventricle heart disease and illuminating the role of those genetic factors in the development of heart failure and other clinical outcomes.

Mitral annular disjunction distance is associated with adverse outcomes in children and young adults with connective tissue disorders

Published On 2025 Sep 08

Journal article

CONCLUSIONS: A small MAD distance can be measured in healthy children and young adults. Children and young adults with CTD have a longer MAD distance than healthy control subjects, and a longer MAD distance is associated with adverse outcomes.


Enrichment of tandem repeat element variants near CHD genes identified by short- and long-read genome sequencing

Published On 2025 Jul 27

Journal article

CONCLUSIONS: In a targeted analysis of de novo and transmitted TR element variants in a large cohort of CHD probands, each individual had ~ 1 de novo TR element variant near a CHD gene, and participants with CHD demonstrate clustering of variants within TR element regions. Long-read sequencing confirmed the majority of TR element variants identified using the gangSTR pipeline. De novo variants in known CHD genes were enriched in participants with CHD, with specific enrichment in TR elements near...
