We report a two-generation family with four females harboring an 8.5Mb heterozygous deletion of 5q15-q21.2 who present with dysmorphic craniofacial features and speech delay. We hypothesize haploinsufficiency of to be contributing to the clinical features observed in this family.

Background: Fragile X syndrome (FXS) is a leading known genetic cause of intellectual disability and autism spectrum disorders (ASD)-associated behaviors. A consistent and debilitating phenotype of FXS is auditory hypersensitivity that may lead to delayed language and high anxiety. Consistent with findings in FXS human studies, the mouse model of FXS, the Fmr1 knock out (KO) mouse, shows auditory hypersensitivity and temporal processing deficits.

Background: Autism spectrum disorder poses challenges in social communication and behavior, while Intellectual disabilities are characterized by deficits in cognitive, social, and adaptive skills, frequently accompanied by stereotypies and challenging behaviors. Despite the progress made in autism spectrum disorder research, there is often a lack of research focusing on individuals with co-occurring autism spectrum disorder and intellectual disability. Robot-assisted autism therapies are effective in addressing these needs.

The visual environment of sign language users is markedly distinct in its spatiotemporal parameters compared to that of non-signers. Although the importance of temporal and spectral resolution in the auditory modality for language development is well established, the spectrotemporal parameters of visual attention necessary for sign language comprehension remain less understood. This study investigates visual temporal resolution in learners of American Sign Language (ASL) at various stages of acquisition to determine how experience with sign language affects perceptual sampling.

Background: When performing a picture description task, healthy individuals tend to look only briefly at a target before beginning its description, after which they move promptly onto the next target. This sequence may be disrupted in those with cognitive impairment. Just as cognitively impaired individuals produce greater numbers of disfluencies and pauses, those with mild cognitive impairment (MCI) may delay speech production by extending their gaze behavior towards a target before beginning its description.

Background: The Israeli population, primarily comprised of Israeli Jews (74%) and Arabs (21%), is one of the most diverse aging societies around the world. The need for brief, accurate, and culturally appropriate cognitive measures in Israel is high, as they can facilitate early detection of cognitive disorders across clinical settings. We examined the discrimination accuracy and concurrent validity of the brief Tablet-based Cognitive Assessment Tool (TabCAT) Brain Health Assessment (BHA) battery in a multicultural Israeli sample.
