All diffraction data were indexed and integrated using MOSFLM (Leslie and Powell, 2007 ) and scaled using SCALA (Evans, 2006 (link)). All models were refined with REFMAC5 (Murshudov et al., 2011 (link)).
The DYRK1A structure was solved by molecular replacement using Phaser (McCoy et al., 2007 (link)) and a search ensemble of the coordinates from two CLK kinases (PDB ID codes 2EXE and 1Z57). Four molecules were present in the asymmetric unit and, after NCS averaging and density modification in dm (Cowtan, 1994 ), the resulting phases could be utilized in ARP/wARP (Langer et al., 2008 (link)) to autobuild the main parts of one of the molecules in the asymmetric unit. After further model building in Coot (Emsley et al., 2010 (link)), this molecule was used to generate the other three molecules for restrained refinement with tight NCS restraints. Rebuilding and refinement (including TLS parameters) resulted in the final model.
The DYRK1A peptide complex and the DYRK2 structure were both solved by molecular replacement using Phaser, with the structure of the inhibitor-bound DYRK1A as a search molecule.

Recombinant DYRK1A was purified
as previously described60 (link) and was treated
with TEV protease to remove the N-terminal His6 tag. The
kinase at ∼13–15 mg/mL in 50 mM HEPES, pH 7.5, 500 mM
NaCl and 5 mM DTT was incubated with the inhibitors at 1 mM prior
to crystallization. Crystals were obtained using the sitting drop
vapor diffusion method at 4 °C using either 2 M ammonium sulfate,
0.2 M Na/K tartrate, 0.1 M citrate, pH 5.6 (for 5s and 5t), or 37% PEG 400, 0.2 M lithium sulfate, 0.1 M Tris, pH
8.8 (for 5j), as the reservoir solutions. Diffraction
data collected at Diamond Light Source, beamline I04-1, were processed
with XDS71 (link) or mosflm72 (link) and subsequently scaled with Scala from CCP4 suite.73 (link) Structures were determined by molecular replacement
method using Phaser74 (link) and the coordinates
of DYRK1A structure60 (link) as a search model.
Iterative cycles of manual model building in COOT75 (link) alternated with refinement using Refmac,76 (link) and a TLS model calculated from TLSMD server77 (link) was performed. The geometric correctness of
the final model was verified with MolProbity.78 (link) Data collection and refinement statistics are summarized in Table 3. DYRK1A-ligand complexes (pdb id): DYRK1A-5j (4YLJ); DYRK1A-5s (4YLK); DYRK1A-5t (4YLL).

We performed a detailed clinical assessment of all eight patients with sporadic DYRK1A mutations, including the five new patients described here as well as three individuals with ASD for whom there was previously only limited clinical information available.7 (link) Additionally we assessed a ninth patient whose variant was determined to not likely lead to DYRK1A loss of function. Patients underwent a thorough assessment, including physical exam, dysmorphological assessment, a review of medical history, and comprehensive neurocognitive and diagnostic battery. The battery included clinician observation and parent reporting across domains of cognition, memory, language, motor, executive functioning, social, repetitive and atypical behaviors, and adaptive ability. In addition, psychiatric presentation was evaluated and gold standard ASD assessments (Autism Diagnostic Observation Schedule (ADOS), Autism Diagnostic Interview - Revised, clinical judgment) were completed for patients where possible.

The DS iPSC line was cultured in 10 μM of Rho-associated protein kinases (ROCK) inhibitor (Calbiochem; Y27632) 24 h before electroporation. Single cells (1×107) were harvested using TryPLE select (Invitrogen), resuspended in 1 x PBS and electroporated with a total of 55 μg DNA including five plasmids (XIST, DYRK1A ZFN1, DYRK1A ZFN2, rtTA/puro, and AAVS1 ZFN) with both 3:1 and 5:1 ratios of XIST: rtTA/puro. The electroporation conditions were 220v, and 750 μF (BioRad Gene Pulser II System). Cells were subsequently plated on puromycin-resistant DR4 MEF feeders (Open Biosystems, Cat#: MES3948) in hiPSC medium supplemented with ROCK inhibitor for the first 24 h. Over 300 colonies remained after 12 days of 0.4 μg/ml puromycin selection and 245 randomly chosen individual colonies across 36 pooled wells were examined by interphase DNA/RNA FISH for the presence and expression of XIST, correct targeting and retention of trisomy (since some subclones lacked XIST or showed just two DYRK1A DNA signals). Over 100 individual clones were isolated and characterized, and those of interest, containing targeted XIST on one of three DYRK1A loci, were frozen. Six single target clones with good pluripotent morphology, OCT4 positive staining, correct targeting to one trisomic chromosome, and good XIST RNA paint were expanded for further characterization. One double and one triple target line, two non-target clones, and one disomic clone were also isolated and frozen. Targeting and correct chromosome number (47) was confirmed by interphase and metaphase FISH and genome integrity by high resolution G-band karyotype and CGH array.

Colocalization analysis takes into account five hypotheses: H0 (no association between the locus and either trait), H1 (locus has an association with first trait only), H2 (locus has an association with second trait only), H3 (locus has an association with both traits but driven by different SNPs which are not in linkage disequilibrium (LD)), H4 (locus has an association with both traits driven by same SNPs). For Project 3: Colocalization pipeline, we considered colocalization analysis with a posterior probability of colocalization in H4 (PPH4) greater than 0.8 to be significant. We utilized the coloc R package21 ,22 (link) and summary statistics from ref. 7 (link). We used eQTL data from a cerebellar cortical meta-analysis of four cohorts23 (link), publicly available from the AMP-AD Knowledge Portal24 . As an example for our pipeline, we extracted the region ± 500 kb around DYRK1A, nominated in Nalls et al. 2019, from the GWAS summary statistics and eQTL data. To visualize the results, we employed the eQTpLot R package25 (link), which can generate different plots for GWAS and eQTL signal colocalization, as well as the correlation between their p values and enrichment of eQTLs among variants and LD of loci of interest, allowing efficient and intuitive visualization of gene expression and trait interaction. We used our previously generated results for DYRK1A and whole brain eQTL as an example for creating visualizations using this package.

The 3D crystal structure of human Cytochrome P450 1A2 (CYP1A2, PDB ID: 2HI4), Dual specificity tyrosine-phosphorylation-regulated kinase 1A (DYRK1A, PDB ID: 7A4O), Dual specificity tyrosine-phosphorylation-regulated kinase 1B (DYRK1B, PDB ID: 7A4O), and Dual specificity protein kinase (CLK1, PDB ID: 1Z57) proteins were retrieved by a research collaborator from the structural bioinformatics protein data bank (RCSB-PDB) (https://www.rcsb.org/ accessed on 28 July 2022). The molecular interaction of BP with the predicted target proteins was carried out using AutoDock Tools 4.0 [60 (link)]. Input files such as pdbqt of both the BP and target proteins, grid parameter, and docking parameter were prepared as previously described using AutoDock [61 (link)]. BP with a minimum binding energy (ΔG) towards the target proteins during the post-docking analysis was considered for a further molecular simulation analysis [62 (link)]. Molecular dynamic simulations of 100,000 picoseconds (ps) were performed to examine the flexibility and stability of the analog BP with CYP1A2 and DYRK1A enzymes at 300 K using the Groningen Machine for Chemical Simulations (GROMACS 5.1.2) package [63 (link)]. System preparation, system equilibration, and post-equilibration procedures were performed as stated in the Methods in Supplementary Materials. Analyses of the root-mean-square deviation (RMSD), root-mean-square fluctuation (RMSF), and Radius of gyration (Rg) between the protein and BP in each frame were accomplished using the GROMACS command utilities.

Total protein in each sample was extracted using RIPA lysis buffer (Beyotime Biotechnology). The protein concentration was determined using the BCA protein concentration quantification kit (Beyotime Biotechnology). Denatured proteins were separated using 5× SDS-PAGE and transferred to PVDF membranes followed by blocking with 5% nonfat dry milk in Tris-buffered saline with 0.05% Tween 20 and probed with primary antibodies overnight at 4℃. Following washing, membranes were incubated with goat peroxidase-conjugated secondary antibodies at 37℃ for 2 hours. The reactions were detected using the Pierce ECL Western Blotting Substrate (Thermo Fisher). The bands were visualized via exposure to an x-ray beam in a dark room and semi-quantified analyzed using Tanon Image software. The ratio of the densitometric values of NFATc1, phosphorylated NFATc1, or DYRK1A bands to those of β-actin bands were used to determine relative expression. The primary and secondary antibodies included: mouse anti-β-actin (43 kDa, 1:1,000 dilution; Santa Cruz), mouse anti-NFATc1 (110,140 kDa, 1:500; Wanleibi), rabbit anti-NFATc1-P (phospho S237, 110, 140 kDa, 1:1,000; Abcam), rabbit anti-DYRK1A (46, 60, 86 kDa, 1:1,000; Abcam), Peroxidase Affini Pure Donkey Anti-Mouse IgG (H+L, 1:5,000; Jackson), and Peroxidase Affini Pure Goat Anti-Rabbit IgG (H+L, 1:10,000; Jackson).

RNA was obtained from cortical tissue of Ts2Cje and Eu mice treated with vehicle or the KYCCSRK peptide. Tissues were lysed with an appropriate volume of QIAzol Reagent (QIAzol Lysis Reagent, Qiagen, Hilden, Germany). Subsequently, chloroform was added (1:5, Sigma-Aldrich, St. Louis, MO, USA), and samples were kept for 3 min at RT before being centrifuged at 12,000 rpm and 4 °C for 15 min. Following that, isopropanol (100%, Sigma-Aldrich, St. Louis, MO, USA) was added to each sample at RT for 10 min to separate RNA. Then, samples were centrifuged at 12,000 rpm and 4 °C for 15 min. The supernatant was discarded, and pellets were washed with 75% ethanol (Sigma-Aldrich, St. Louis, MO, USA) followed by further centrifugation at 7500 rpm and 4 °C for 5 min. The pellets were resuspended in RNAse-free H2O (Sigma-Aldrich, St. Louis, MO, USA). The RNA was quantified using the Biospec Nano reverse transcribed using the cDNA High-Capacity kit (Applied Biosystems, Foster City, CA, USA), including reverse transcriptase, random primers, and buffer according to the manufacturer’s instructions. The cDNA was produced through a series of heating and annealing cycles in the MultiGene OPTIMAX 96-well Thermocycler (LabNet International, Edison, NJ, USA). Real-time PCR was carried out using the SensiFAST™ SYBR® and No-ROX Kit (Bioline, London, UK) in a CFX Connect Real-Time PCR machine (Bio-Rad Laboratories, Hercules, CA, USA). Primers used for the RT-PCR are DYRK1A FW: 5′-TGGGGCAGAGGATATACCAGT-3′ and RV: 5′- GTCGATAGCAAGGTCATAAGGCA-3′ and BACE1 FW 5′-GGATTATGGTGGCCTGAGCA-3′ RV 5′-CACGAGAGGAGACGACGATG-3′ (BACE1: NM_011792.7; DYRK!A: NM_007890.2).

We obtained all the network's key node genes with statistical significance, including ZNF460, FBN1, CDK6, BTG2, CBX6, DYRK1A, and so on. We obtained some significant pathways corresponding to hub genes (Fig. 5). The figure shows that the PI3K/AKT signaling pathway was the most enriched KEGG pathway. In addition, GO-BP analysis reveals that Ras protein signal transduction and extracellular structure organization are the most enriched biological process. GO-CC analysis revealed that the enriched cellular components were collagen-containing extracellular matrix, cell leading edge, ruffle, and other parts. GO-MF analysis revealed that protein serine/threonine kinase activity, extracellular matrix structural constituents, and growth factor binding were the top enriched molecular functions.
