Professor of Medicine, Harvard Medical School
Division of Genetics, Brigham and Women’s Hospital
Dr. Maas is
Professor of Medicine (Genetics) at Harvard Medical School, and former Chief of the
Division of Genetics at Brigham and Women’s Hospital, a position he has held
for over 20 years. His credentials
include 30 years on the HMS faculty as a physician-scientist, tenure as an HHMI
Investigator, election to the ASCI and as a Fellow of the AAAS, an NIH MERIT
Award, and many others. Faculty of the BWH
Division of Genetics include members of HHMI, NAS, and NAM, as well as past
winners of the Gairdner, Lasker, and Breakthrough Prizes. Dr. Maas has also
been PI of the BWH Biomedical Research Institute Director’s Transformative
Award that provides institutional support to Brigham Genomic Medicine
(BGM). BGM is an integrated clinical and
research program that enables BWH faculty from multiple BWH departments and
divisions to diagnose genetic disorders and to discover new monogenic disease
genes via WES/WGS. He is also a prior PI
of and is now on the External Scientific Advisory Group of an NIH U01
Consortium called FaceBase that employs WES/WGS to identify genes that cause
craniofacial birth defects, Director of the Harvard Undiagnosed Disease
Clinical Site (HUDN-CS) Genome Analysis Team.
In addition, he previously directed a large NIH U54 Interdisciplinary
Research Consortium focused on systems biology approaches to organ regeneration. His research focuses on the developmental
genetics of vertebrate organogenesis, on disease gene discovery, and on the
clinical implementation of genomic medicine.
Dr. Maas
earned his undergraduate degree in chemistry from Dartmouth College before matriculating
in the Vanderbilt M.D., Ph.D. program. Dr. Maas then pursued his internship and
residency in Internal Medicine at Brigham and Women’s Hospital and completed
his postdoctoral training with Dr. Philip Leder in the Department of Genetics
at Harvard Medical School. He joined the HMS faculty in the Division of
Genetics at Brigham in 1989.

Nizon-Isidor syndrome is a rare disorder caused by heterozygous variants in MED12L, with only eight documented cases in the literature. Here, we present three additional cases of this syndrome. Proband 1 was a 7-year-old female who presented with developmental delay, right-leg hemihypertrophy, laryngeal cleft, esotropia, abnormal skin pigmentation, sectoral iris hypopigmentation, dysphagia, periventricular nodular heterotopia, seizures, morbid obesity, and a pelvic kidney. Genome sequencing (GS)...

Genomics for rare disease diagnosis has advanced at a rapid pace due to our ability to perform in-depth analyses on individual patients with ultra-rare diseases. The increasing sizes of ultra-rare disease cohorts internationally newly enables cohort-wide analyses for new discoveries, but well-calibrated statistical genetics approaches for jointly analyzing these patients are still under development. The Undiagnosed Diseases Network (UDN) brings multiple clinical, research and experimental...
