Characterizing the autism spectrum phenotype in DYRK1A-related syndrome.
Kids with DYRK1A-related ASD look like typical ASD plus extra sensory-seeking—keep your autism protocol, just watch (and plan for) the sensory spike.
01Research in Context
What this study did
The team looked at kids who have DYRK1A-related syndrome. They wanted to see if these children show the same autism traits as kids with everyday idiopathic ASD.
They used standard autism checklists and IQ tests. Parents also answered questions about sensory habits.
What they found
Children with DYRK1A syndrome met autism criteria in almost the same way as typical ASD kids. The big difference: they sought out extra sensory input more often.
In plain words, they touched, mouthed, or spun objects even more than peers with regular ASD plus intellectual disability.
How this fits with other research
Watson et al. (2007) first showed that over 90% of people with idiopathic ASD have sensory quirks. Diemer et al. (2023) now extends that finding, saying DYRK1A kids push the sensory-seeking dial even higher.
Peters et al. (2013) used the same compare-to-idiopathic-ASD design in MECP2 duplication boys. Both studies conclude: genetic-ASD largely mirrors regular ASD, with small add-ons.
Badia et al. (2013) profiled ASD youth without intellectual disability and found wide comorbidity. Diemer et al. (2023) maps the opposite edge—ASD with definite ID—closing the phenotypic circle.
Why it matters
You can keep using ADOS, ADI-R, or other familiar tools for DYRK1A clients. Just add a sharp sensory probe: ask about licking toys, staring at lights, or rubbing surfaces. When these behaviors pop up, build in extra sensory breaks or safe chew items. The core autism program stays the same; the sensory piece just gets louder.

03Original abstract
Likely gene-disrupting (LGD) variants in DYRK1A are causative of DYRK1A syndrome and associated with autism spectrum disorder (ASD) and intellectual disability (ID). While many individuals with DYRK1A syndrome are diagnosed with ASD, they may present with a unique profile of ASD traits. We present a comprehensive characterization of the ASD profile in children and young adults with LGDs in DYRK1A. Individuals with LGD variants in DYRK1A (n = 29) were compared to children who had ASD with no known genetic cause, either with low nonverbal IQ (n = 14) or average or above nonverbal IQ (n = 41). ASD was assessed using the ADOS-2, ADI-R, SRS-2, SCQ, and RBS-R. Quantitative score comparisons were conducted, as were qualitative analyses of clinicians' behavioral observations. Diagnosis of ASD was confirmed in 85% and ID was confirmed in 89% of participants with DYRK1A syndrome. Individuals with DYRK1A syndrome showed broadly similar social communication behaviors to children with idiopathic ASD and below-average nonverbal IQ, with specific challenges noted in social reciprocity and nonverbal communication. Children with DYRK1A syndrome also showed high rates of sensory-seeking behaviors. Phenotypic characterization of individuals with DYRK1A syndrome may provide additional information on mechanisms contributing to co-occurring ASD and ID and contribute to the identification of genetic predictors of specific ASD traits.
