MARBLES

March 1, 2006 - September 30, 2023

ASD sibling risk study. Early identification of possible ASD. Environmental factors that may contribute to the development of ASD. First prenatal study of its kind.

What are the goals of the study?

MARBLES (Markers of Autism Risks in Babies – Learning Early Signs) is a longitudinal study to investigate possible risk factors that may contribute to the development of autism. Launched in 2006, the study enrolls women who already have a child diagnosed with autism and who are pregnant or planning an additional pregnancy. Parents of a child diagnosed with autism are more likely to have another child with autism compared to the general population (currently ~1 in 5 vs. 1 in 59).

What will happen during the visit or online?

Responses to surveys about family medical history, lifestyle and other factors that may influence your baby’s development. Details about your health, household product use and environment during pregnancy and until your child is 3 years of age. Urine, blood, environmental and other samples during and after pregnancy. Permission to access medical records concerning your child and your pregnancy. Permission for developmental testing of your child at 6, 12, 24 and 36 months of age

How will this help families?

Tracking baby siblings growth and development at various time points until child is 36mo.
