Every dollar donated to the IFF’s research fund supports rigorous, peer-reviewed FOXP1 research. Below are the projects we’ve funded to date and the areas where community giving is driving discovery.

Where Your Gift Goes

Community-funded. Peer-reviewed. Field-advancing.

The Foundation awards research grants through an open, competitive process. Every proposal is reviewed by our Scientific Advisory Board against clear scientific criteria and community priorities.

The projects listed here are the direct result of donations from families, friends, and partners around the world.

The Portfolio

Funded Projects to Date

Funded in 2025
Basic Science 2025

Investigating FOXP1 dosage restoration in a new mouse model

Dr. Yann Herault · Institute of Genetics and Molecular and Cellular Biology, Strasbourg, France

Testing whether restoring normal FOXP1 protein levels can correct key symptoms of FOXP1 syndrome. By selectively reactivating FOXP1 at different developmental stages, the team will assess impact on activity levels, vocalisation and lean mass — and establish a valuable new mouse model for the wider scientific community.

Basic Science 2025

Modeling FOXP1 syndrome using human brain organoids

Dr. Bennett Novitch · University of California, Los Angeles

Using patient-derived stem cells to generate three-dimensional brain organoids and assembloids that replicate the neural network disruptions caused by FOXP1 variants — a human-based platform with the potential to accelerate preclinical therapeutic testing.

Trial Readiness 2025

Advancing clinical trial readiness through objective neurodevelopmental phenotyping

Dr. Rujuta Wilson & Dr. Catherine Lord · University of California, Los Angeles

Scalable, objective assessments of motor function, language, cognition and autism symptoms in children aged 1–20. In-person and remote testing allows broad participation, refining the assessment tools future clinical trials will depend on.

Funded in 2024
Basic Science 2024

Three-dimensional organoid model of FOXP1 syndrome

Dr. Joseph Buxbaum · Seaver Autism Center, Mount Sinai, with Rumi Scientific

Developing a medium-to-high throughput assay to screen compound libraries for candidates that normalise the FOXP1 organoid phenotype — the first step in a drug discovery pipeline built on patient-derived cell lines.

Basic Science 2024

Functional restoration of FOXP1 haploinsufficiency using AAV-mediated gene rescue

Dr. Genevieve Konopka & Dr. Jay Gibson · UT Southwestern Medical Center

Delivering a working copy of FOXP1 to brain cells via AAV viral vector in a mouse model that mirrors the genetics of FOXP1 syndrome, then testing whether gene replacement corrects behavioural deficits — and how late in development it still works.

Basic Science 2024

Testing a potential treatment in striatal organoids from individuals with FOXP1 variants

Dr. Henning Fröhlich, Prof. Gudrun Rappold & Dr. Julia Ladewig · Heidelberg University, Germany

Investigating whether the mitochondrial dysfunction and PDE10A dysregulation found in mouse models also appear in human cells, and whether the inhibitor MP-10 improves mitochondrial function in patient-derived striatal organoids.

Trial Readiness 2024

FOXP1 qualitative assessment and Clinical Global Impression Scale development

Dr. Paige Siper · Seaver Autism Center, Mount Sinai

No tool currently exists to measure treatment response in FOXP1 syndrome. This study quantifies key parental concerns across age groups to build a FOXP1-specific CGI scale for use as an endpoint in future clinical trials.

Research Priorities

Where we focus community-
funded science
