Characterization of (A)Typical Sensorimotor Pathways in Individuals With Autism

The Movement ABC-3 (Movement Assessment Battery for Children, Third Edition) is a comprehensive, standardized assessment tool for identifying gross and fine motor coordination difficulties in individuals aged 3 to 25, assessing skills like dexterity, aiming, catching, balance, and locomotion.

The Developmental Coordination Disorder Questionnaire (DCDQ) is a parent questionnaire originally developed for estimating gross and fine motor skill difficulties in children. The questionnaire consists of 15 items investigating different subdomains of motor abilities, such as ball skills, complex motor coordination, fine and general motor skills. For each item, parents rate the children's degree of motor coordination on a 5-point scale comparing it to same-age peers.

The Adult Developmental Coordination Disorder/Dyspraxia Checklist (ADC) is a self-report screening tool for adults (16+) to identify potential Developmental Coordination Disorder (DCD/Dyspraxia) by assessing lifelong motor challenges in daily activities

(a) a reaching-and-inserting task involving a ball (ball task), which consists in reaching and grasping a rubber ball (diameter: 6 cm) placed over a support and dropping it in a small basket, provided with a hole large enough (diameter: 7 cm) not to require fine movements; (b) a task requiring grasping a moving ball (ball-rolling task) which requires participants to catch a ball rolling toward them on a curvilinear path off an inclined tabletop. As outcome measure, we will consider the total movement duration (recorded in sec).

Magnetic Resonance (MRI) of the Brain - MRI signal allowing tridimensional multiplanar reconstruction of the brain's structures. Anatomical images obtained with high definition T1 weighted sequences of radio frequencies - the measure is a "signal (in Hz) to noise ratio" which is obtained from each voxel (tiny 3D portions of the brain)

Magnetic Resonance Spectroscopy (MRS) is a non-invasive technique, often used with MRI, that measures the chemical makeup (metabolites) of tissues like the brain.

Exome libraries will be sequenced using the Illumina NextSeq 500 in 100 bp paired end reads. Postsequencing reads will be aligned using BWA Enrichment application on BaseSpace. Variant Call Format file will be then marked using wANNOVAR (Wang Genomics Lab).
