Early Motor Trajectories in Infants at Increased Genetic Likelihood for Autism

Longitudinal motor assessment scores for 93 infants tracked from 3 to 12 months of age. The data compares infants with an older sibling with autism (EL-AutSib), infants with tuberous sclerosis complex (EL-TSC), and a low-likelihood comparison group (LL). It was authored by Sereen C. Wong and published on figshare in 2026.

Use Cases

• Modeling longitudinal motor development based on repeated Alberta Infant Motor Scale (AIMS) assessments at 3, 6, 9, and 12 months.
• Comparing motor trajectory patterns between distinct high-likelihood groups (EL-AutSib and EL-TSC) and a low-likelihood control group.
• Investigating the relationship between early motor scores and later autism diagnosis based on clinical best estimate at 24 or 36 months.

Strengths

• Includes longitudinal data with four assessment timepoints per infant.
• Compares three distinct participant groups (EL-AutSib, EL-TSC, LL) with a total of 93 infants.
• Uses a standardized clinical assessment tool, the Alberta Infant Motor Scale (AIMS).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The sample size for the EL-TSC group (16 infants) is relatively small.
