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.

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...


Genetic diagnosis of facioscapulohumeral muscular dystrophy type 1 using rare-variant linkage analysis and long-read genome sequencing

Published On 2024 Dec 13

Journal article

Facioscapulohumeral dystrophy type 1 (FSHD1) is a progressive, debilitating skeletal myopathy that requires a multimodal approach for complete molecular characterization of pathogenic genotypes. Here, we report genomic analyses of a family with suspected FSHD1. We first performed short-read genome sequencing, followed by parametric linkage analysis using rare variants to map the disease locus to a single 1.7 Mb interval on chromosome 4q35.2 with a logarithm of the odds score of 3.2. We then used...
