De Rubeis lab


We study the developmental defects resulting from disruptive mutations in novel high-risk genes identified from our ongoing large-scale genomic studies in autism (ASD) and intellectual disability (ID). We take a genetics-first approach for functional analyses in cellular and mouse models and we strive to take into account clinically relevant aspects that emerge from patient-based research.

We are part of the Seaver Autism Center for Research and Treatment at the Icahn School of Medicine at Mount Sinai in New York. The Seaver Center is a fully integrated translational research center dedicated to discovering the biological causes of autism and intellectual disability and developing breakthrough treatments.  The lab is affiliated to the Department of Psychiatry, Mindich Child Health and Development Institute and Friedman Brain Institute.

Our group is part of an interdisciplinary pre-clinical team of geneticists, molecular biologists, stem cell researchers, and neuroscientists and has direct interactions with a clinical team of psychiatrists, psychologists, neurologists, and clinical geneticists.

We are currently focusing on two rare genetic disorders: DDX3X syndrome and ADNP syndrome.

Current Projects

DDX3X Syndrome

DDX3X syndrome is a recently identified rare form of X-linked ID that accounts for up to 2% of unexplained cases in females. Affected individuals can also present with ASD, hypotonia, movement disorders and brain anomalies.
DDX3X syndrome is caused by mutations in the DDX3X gene, a gene located on the X chromosome. The gene displays sex differences in its expression. Also, DDX3X mutations display a sexual dichotomy: most mutations are found in females and are not inherited from their parents; the few mutations in males are inherited from apparently asymptomatic mothers.
Our research on DDX3X syndrome seeks to elucidate the molecular, cellular and developmental functions of DDX3X to understand how the neurodevelopmental trajectory in DDX3X syndrome goes awry and develop novel therapeutics.
Our research aims to address three major questions.

What are the molecular functions of DDX3X? 

DDX3X is an RNA helicase shown to regulate mRNA translation. The role of DDX3X in mRNA translation has been almost exclusively studied in non neuronal cells.
In neurons, mRNA translation also occurs at synapses, where it rapidly reshapes the local proteome in response to neuronal activity. Synaptic mRNA translation is critical for the formation and plasticity of synapses, and for learning and memory. We use molecular biology and biochemistry techniques to study the molecular complexes and gene targets of DDX3X in neurons, with the goal of identifying new molecular targets for therapeutic intervention. 

How is DDX3X affecting brain development? 

Individuals with DDX3X syndrome suffers from neurodevelopmental and neurological symptoms. Yet, nothing is known about the role of DDX3Xduring neurodevelopment and the consequent impact of DDX3X mutations on cognition and social behavior. 
We are exploring the cellular and molecular functions of DDX3X during brain development taking advantage of a new mouse model of DDX3X syndrome we generated. We use standardized behavioral testing in juvenile and adult mice and combine them with cellular and in vivo approaches. Once we identify the mechanisms of DDX3X syndrome and reliable phenotypes in the mouse model, novel therapeutics for DDX3X syndrome can be developed and tested.

What are the determinants of sex specificity of DDX3X syndrome?

Individuals with DDX3X syndrome are mostly females with de novo mutations, namely mutations that are not transmitted by their parents. The few males with DDX3X syndrome described in the literature inherit their mutations from their mothers, who appear asymptomatic or have subclinical deficits. What determine these sex differences? Why do the mothers of the affected males do not have DDX3X syndrome?

To address these intriguing questions, we use male and female neuronal models of DDX3X syndrome. We generate male and female embryonic mouse neurons missing DDX3X and study their development and physiology. These models can be used to understand the neurobiology of DDX3X and develop pre-clinical cellular models for drug discovery and testing.

ADNP Syndrome

ADNP syndrome, also called Helsmoortel-VanDerAa syndrome, is a rare neurodevelopmental disorder caused by mutations in the ADNP gene. We are working on establishing and investigating the utility of blood-based biomarkers in ADNP syndrome. Biological signatures in easily accessible biospecimens (e.g., blood) offer powerful tools to predict and measure treatment response during clinical trials. Further, blood-based biomarkers can also help uncovering biological pathways altered in affected individuals, thus offering a window into the mechanisms underlying the disorder. 

ASD Genetics

Enormous progresses have been made in showing that genetics shapes a large fraction of risk for ASD and in identifying specific genes and loci conferring liability. We continue our work with the Autism Sequencing Consortium in aggregating and sequencing large cohorts of individuals with ASD and matched controls collected all over the world.  


Principal Investigator

Silvia De Rubeis, PhD, is an Assistant Professor at the Seaver Autism Center for Research and Treatment, Department of Psychiatry, Mindich Child Health and Development Institute, and Friedman Brain Institute at the Icahn School of Medicine at Mount Sinai.

Dr. De Rubeis is a neuroscientist and geneticist interested in understanding the genetic, molecular and cellular mechanisms underlying autism spectrum disorder (ASD) and intellectual disability (ID).

Dr. De Rubeis completed her bachelor, master and PhD degrees in Cellular and Molecular Biology at the University of Rome Tor Vergata in Rome, Italy. During her PhD and first postdoctoral training in Molecular Neuroscience with Dr. Claudia Bagni at the Katholieke Universiteit Leuven and Vlaams Instituut voor Biotechnologie (VIB) in Leuven, Belgium, she studied how the regulation of mRNA translation shapes the synaptic development in the context of Fragile X syndrome, a leading monogenic cause of ASD and the most common inherited form of ID. During this training, she visited the laboratory of Dr. Eric Klann at the New York University as an EMBO short-term fellow. She then joined the Icahn School of Medicine at Mount Sinai for a second postdoctoral training in Genetics and Genomics in the lab of Dr. Joseph Buxbaum. She studied the role of rare genetic variation in ASD through large-scale exome sequencing analyses and discovered novel genes and loci conferring risk. As part of that collaboration, she continues to lead efforts of a large-scale autism genomic consortium (Autism Sequencing Consortium).

Dr. De Rubeis’ research combines genetics, molecular biology, developmental biology and neuroscience to understand the pathophysiology of ASD and ID. Her team is currently focusing on two rare genetic neurodevelopmental disorders associated with ASD and ID: DDX3X syndrome and ADNP syndrome.



Adele Mossa, PhD | Postdoctoral Fellow

Adele joined the De Rubeis lab in July 2020 after completing her postdoctoral fellowship at the The George Washington University and Rutgers Robert Wood Johnson Medical School in the laboratory of Dr. Chiara Manzini. Adele holds a PhD in Biomedical Sciences/Neurosciences at the University of Pavia (Italy), in the laboratory of Dr. Carlo Sala (CNR, Italy).

Adele studies the role of DDX3X in the morphogenesis and synaptogenesis of cortical neurons using a novel mouse model of DDX3X syndrome. She also investigates the role of the cerebellum in DDX3X syndrome. Her work aims at capturing the pathophysiology of DDX3X syndrome and developing novel treatments. 

After her postdoctoral training, she intends to establish an independent academic career focusing on the neurobiology of neurodevelopmental disorders.
