MARAbio

MARAbio is a precision immunology company advancing science around Maternal Autoantibody-Related Autism (MAR-Autism).

Our MAR-Autism™ Test uses a simple maternal blood test to assess the likelihood of this immune-mediated autism subtype. MARAbio is a precision immunology company offering hope to families facing the prospect and potential impacts of autism by enabling pre-conception screening, likelihood assessment, and informed care. The MAR-Autism™ Test is a maternal blood test that identifies specific autoantibodies linked to an immune-related subtype of autism, helping providers and families better understand a child’s likelihood of MAR-Autism diagnosis with >95% specificity. The test can also inform a family of likelihood of MAR-Autism in future children prior to pregnancy.

A negative MAR-Autism™ Test result means the specific maternal autoantibody patterns associated with MAR-autism were not detected.

That lowers the likelihood of the MAR-autism subtype in a future child, but it does not rule out autism.
Autism can involve other biological, genetic, and environmental factors, and family history also plays an important role in understanding individual likelihood.

A healthcare provider can help put your MAR-Autism™ Test results into context alongside your clinical and family history.

Autism is now more common in children than peanut allergy.

That comparison helps put autism prevalence into perspective and highlights why understanding its different biological pathways is so important.

Maternal Autoantibody-Related autism, or MAR-autism, is one biologically defined, immune-associated subtype associated with specific maternal autoantibody patterns.

Understanding subtype can provide families with additional biological information to bring into conversations with healthcare providers and future family planning.

For years, autism research has asked whether specific biological pathways could help explain why autism develops differently across children.

Research led by Dr. Judy Van de Water at the UC Davis MIND Institute helped identify maternal autoantibody patterns associated with MAR-autism, a biologically defined, immune-associated subtype of autism.

That discovery gave researchers and families something more specific to examine within a much broader diagnosis.

MAR-autism does not account for every case of autism. Research suggests it accounts for approximately 10–20% of autism cases.

Identifying one defined pathway can provide essential information for families and healthcare providers.

Autism can involve different biological pathways, which is why researchers are continuing to identify more specific subtypes within the broader diagnosis.

Maternal Autoantibody-Related autism, or MAR-autism, is one biologically defined, immune-associated subtype associated with specific maternal autoantibody patterns.

Understanding subtype can add another layer of biological information for families and healthcare providers.

For many families, one of the hardest parts of autism is not knowing what to expect or what information may be relevant as they plan for the future.

The MAR-Autism™ Test can provide more specific information about one identified subtype of autism.

For families with a positive result, that information can help guide conversations with healthcare providers about development, evaluation, support, siblings, and future family planning.

Having that context does not answer every question, but it can give families something more specific to work with.

Researchers have spent more than 20 years studying how maternal autoantibodies may be connected to autism.

In MAR-autism, specific maternal autoantibody patterns are associated with proteins involved in fetal brain development. That research has helped define Maternal Autoantibody-Related autism as a biologically defined, immune-associated subtype of autism.

The MAR-Autism™ Test looks for these patterns using a blood sample from the mother and can provide families and healthcare providers with additional biological information to bring into conversations about autism and future family planning.

An autism diagnosis can answer one important question, but families may still want to understand more about the biology behind it.

MAR-autism is one identified subtype of autism associated with specific maternal autoantibodies.10–20% of all cases of autism are caused by MAR-autism.

The MAR-Autism™ Test can identify whether those autoantibodies are present and provide more specific information to discuss with a healthcare provider.

For some families, having that additional information can offer essential insight into one specific type of autism and help guide the conversations that come next.

The difference we typically see between boys and girls with autism changes with MAR-autism.

MAR-autism is one biologically defined, immune-associated subtype of autism, and research has found boys and girls are affected in equal numbers.

That distinction is another example of why understanding biological subtype can matter. It can give families and healthcare providers more specific information to consider alongside the broader autism picture.

“Find a nice institution for him and get on with your life.”

That was the advice Chuck and Sarah received after their three-year-old son was diagnosed with profound autism.

Their answer was immediate: “We’re not doing that.”

They believed there had to be better answers. That belief became a mission to search for rigorous science and a clearer path forward for families.

Today, precision immunology is helping identify biological subtypes of autism, including MAR-autism. The MAR-Autism™ Test identifies associated maternal autoantibody patterns through a blood sample from the mother.

The answers Chuck and Sarah needed did not exist then. Their refusal to stop searching still matters now.

For Marnin Kligfeld, MARAbio’s mission began long before the company existed.

It began when his two-year-old daughter Leah started losing her words and stopped making eye contact; the people her parents turned to for help told them they were overprotective.

Nearly a year passed before Leah was diagnosed with autism. Marnin has never forgotten that year or what it felt like to know something was different without having a clear path forward.

That experience became a decades-long commitment to rigorous autism science. His search eventually led him to Dr. Judy Van de Water and research pointing to a distinct immune-mediated subtype of autism.

For Marnin, this work has never been abstract. It began with one family searching for answers and became a mission to help other families find them sooner.
