AI Article Synopsis
- Likely gene-disrupting variants in the DYRK1A gene cause DYRK1A syndrome, which is linked to autism spectrum disorder (ASD) and intellectual disability (ID).
- A study compared 29 individuals with DYRK1A syndrome to other children with ASD, assessing their social communication and behaviors with confirmed diagnostic tools.
- Results indicated that those with DYRK1A syndrome exhibit similar social communication traits as individuals with idiopathic ASD, along with specific challenges and high rates of sensory-seeking behaviors, highlighting potential genetic predictors for ASD traits.
Article 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.

A growing number of therapies are being developed to target the cell cycle machinery for the treatment of cancer and other human diseases. Consequently, a greater understanding of the factors regulating cell cycle progression becomes essential to help enhance the response to these new therapies. Here, using data from the Cancer Dependency Map, we identified the poorly-studied factor FAM53C as a new regulator of cell cycle progression.

Article Synopsis
- * A new plasma test measuring p-tau212 levels shows high accuracy in detecting AD-related changes and was tested in 245 plasma and 114 cerebrospinal fluid samples using advanced technology.
- * Results indicate a strong correlation between plasma and CSF p-tau212 levels, with elevated levels in individuals with prodromal and dementia stages of DS, demonstrating high diagnostic accuracy in distinguishing between asymptomatic and symptomatic cases.

Introduction: DYRK1A syndrome, also known as "Intellectual developmental disorder, autosomal dominant 7," is a syndromic intellectual disability characterized by dysmorphic features including deep-set eyes, prominent ears, and retrognathia. Patients have neurodevelopmental problems, ocular anomalies, and multisystem phenotypes. Most cases result from single nucleotide variants causing DYRK1A-haploinsufficiency, while deletions occur in < 15% of cases.

Dual-specificity tyrosine-regulated kinase 1 A (DYRK1A) is crucial in neurogenesis, synaptogenesis, and neuronal functions. Its dysregulation is linked to neurodegenerative disorders like Down syndrome and Alzheimer's disease. Although the development of DYRK1A inhibitors has significantly advanced in recent years, the selectivity of these drugs remains a critical challenge, potentially impeding further progress.
