Richard Maas

M.D., Ph.D.

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.

Undiagnosed Disease Network collaborative approach in diagnosing rare disease in a patient with a mosaic CACNA1D variant

Published On 2024 Mar 21

Journal article

The Undiagnosed Disease Network (UDN) is comprised of clinical and research experts collaborating to diagnose rare disease. The UDN is funded by the National Institutes of Health and includes 12 different clinical sites (About Us, 2022). Here we highlight the success of collaborative efforts within the UDN Clinical Site at Vanderbilt University Medical Center (VUMC) in utilizing a cohort of experts in bioinformatics, structural biology, and genetics specialists in diagnosing rare disease.

Recurrent ATP1A1 variant Gly903Arg causes developmental delay, intellectual disability, and autism

Published On 2024 Mar 20

Journal article

ATP1A1 encodes a sodium-potassium ATPase that has been linked to several neurological diseases. Using exome and genome sequencing, we identified the heterozygous ATP1A1 variant NM_000701.8: c.2707G>A;p.(Gly903Arg) in two unrelated children presenting with delayed motor and speech development and autism. While absent in controls, the variant occurred de novo in one proband and co-segregated in two affected half-siblings, with mosaicism in the healthy mother. Using a specific ouabain resistance...
