In Memoriam: Richard Maas

M.D., Ph.D.

Professor of Medicine, Harvard Medical School

Division of Genetics, Brigham and Women’s Hospital

Dr. Maas was 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 held for over 20 years.  His credentials included 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 other accomplishments.  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 was also a 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 was also involved in and a prior PI of 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 focused 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.

Biallelic LAMP3 Variants in Five Families with Interstitial Lung Disease: Evidence of a Disease-Gene Association

Published On 2026 Feb 07

Journal article

CONCLUSIONS: Biallelic LAMP3 variants are associated with an interstitial lung disease phenotype with variable expressivity. Evaluation for LAMP3 variants should be considered in individuals with unexplained interstitial lung disease.


Phenotypic Variability and Paternal Inheritance of a CHD8 Variant Causing Intellectual Developmental Disorder With Autism and Macrocephaly Confirmed by Epigenetic and Structural Analyses

Published On 2025 Dec 17

Journal article

CONCLUSION: We describe the case of IDDAM caused by a paternally inherited CHD8 variant. Our findings highlight the importance of considering parental inheritance in IDDAM diagnoses and suggest epigenetic and structural biology analyses as valuable tools for reclassifying VUS when variant pathogenicity remains uncertain.
