Dr. Roberts’s early work focused on gene discovery for one of
the Rasopathies, Noonan syndrome (NS), a multiple congenital anomaly disorder
that is the second most common genetic cause of congenital heart disease in
children after Trisomy 21. Over the last 14 years, there has been a rapid
evolution in our understanding of the molecular genetic causes of Noonan
syndrome, with nine genes now identified, explaining approximately 80% of
cases. These discoveries have enabled the widespread use of next-generation
sequencing testing by clinicians for earlier and more exact diagnosis. For more
than 10 years Dr. Roberts has followed a cohort of over 200 individuals with NS
for the purpose of genotype-phenotype analysis. She has also investigated the
influence of these gene mutations on learning, memory and long-term outcomes.
This work has informed anticipatory management guidelines published for
clinicians caring for children and adults with this diagnosis.
Dr. Roberts is Director of the Cardiovascular Genetics Research Program. and is an Attending Physician in Genetics and Cardiology and sees patients at Boston Children’s Hospital.

Variants with large effect contribute to congenital heart disease (CHD). To date, recessive genotypes (RGs) have commonly been implicated through anecdotal ascertainment of consanguineous families and candidate gene-based analysis; the recessive contribution to the broad range of CHD phenotypes has been limited. We analyzed whole exome sequences of 5,424 CHD probands. Rare damaging RGs were estimated to contribute to at least 2.2% of CHD, with greater enrichment among laterality phenotypes...
Journal article
Neurodevelopmental impairments associated with congenital heart disease (CHD) may arise from perturbations in brain developmental pathways, including the formation of sulcal patterns. While genetic factors contribute to sulcal features, the association of noncoding de novo variants (ncDNVs) with sulcal patterns in people with CHD remains poorly understood. Leveraging deep learning models, we examined the predicted impact of ncDNVs on gene regulatory signals. Predicted impact was compared between...
