 <h2>Description</h2>
 <p>
 The <a href="https://sparkforautism.org/" target="_blank">Simons Foundation Autism Research
 Initiative (SFARI)</a> recruited a large cohort of families with autistic children who provided
 DNA samples and phenotypes. 54,558 families, parents and their children were sequenced, a total
 of 142,357 individuals with whole-exome (WES) and 12,519 with whole-genome sequencing (WGS).
 The data contains 32,559 trios and 8,895 quads (one sibling without autism), and 824 twins.
 </p>
 
 <p>
 The same frequencies shown here are also available publicly on the
 <a href="https://genomes.sfari.org/" target="_blank">SFARI Genome Browser</a>.
 See (SPARK et al, Neuron 2018) for details.

 <h2>Data Access</h2>
 <p>
 The data can be explored interactively with the
 <a href="../cgi-bin/hgTables">Table Browser</a> or the
 <a href="../cgi-bin/hgIntegrator">Data Integrator</a>.
 For programmatic access, our <a href="https://api.genome.ucsc.edu">REST API</a> can be used; the
 track name is <em>sfariSparkExomes</em>.
 For bulk download, the VCF file can be obtained from
-<a href="http://hgdownload.soe.ucsc.edu/gbdb/$db/varFreqs/" target="_blank">our download server</a>.

 Allele frequencies can also be displayed on the
 <a href="https://genomes.sfari.org/" target="_blank">SFARI Genome Browser</a>.
 Full CRAMs and VCFs with genotypes are available from
 <a href="https://base.sfari.org/" target="_blank">SFARI Base</a>.
 They require a data access request, which is usually reviewed quickly. More information is

 <h2>Methods</h2>
 
 <p>The genome browser track project was approved by the Simons Foundation under request
 number 14584.1. WES and WGS data were downloaded from
 <a href="https://base.sfari.org/" target="_blank">SFARI Base</a>.
 pVCFs were downloaded, anonymized with a script using bcftools and its &quot;fill-tags&quot; plugin and
 normalized. There was no minimum allele frequency cutoff.</p>
 
 <p>The methods are documented as follows by SFARI:</p>
 <ul>
   <li>
     <b>WGS</b>:
     This release consists of sequence and variant call data for 12,519
     unique individuals, of which 12,517 (99.98%) have available genome-wide
     SNP genotype data. Sequencing and genotyping of all samples in this
     release was performed at New York Genome Center (NYGC). DNA from saliva
     samples were extracted and prepared with PCR-free methods and sequenced
     with paired-end sequencing of 150 bases on the Illumina NovaSeq 6000
     system. Alignment of reads to the human reference genome version
     GRCh38, duplicate read marking, and Base Quality Score Recalibration
     (BQSR) were performed by New York Genome Center (NYGC). Whole-genome
     sequencing data were processed using a standardized, functionally
     equivalent CCDG pipeline with alignment to the GRCh38DH (1000 Genomes)
     reference using BWA-MEM v0.7.15 (deterministic settings, no -M, use of
     .alt contigs), Picard-equivalent duplicate marking (Picard &ge;2.4.1 or
     equivalent), no indel realignment, and base quality score recalibration
     with GATK (dbSNP138, Mills and 1000G gold-standard indels, known
     indels). Final outputs were stored as lossless CRAM files with
     complete SAM-compliant read-group annotations and mandatory 4-bin
     base-quality compression (Q2&mdash;6, 10, 20, 30), and all implementations
     were validated for functional equivalence across centers before use.
     Variant Calling was performed using DeepVariant. See
     <a href="https://github.com/CCDG/Pipeline-Standardization/blob/master/PipelineStandard.md"
     target="_blank">CCDG pipeline details</a>.
   </li>
   <li>
     <b>WES</b>: This release contains
     sequence data for 142,357 individuals and genotyping data for
     141,368 individuals. DNA was sequenced from saliva for all
     samples and all participants consented to having their genetic
     data shared by Regeneron. Exomes for all samples were sequenced with
     short-read, paired-end sequencing of 150 bases on Illumina
     NovaSeq 6000 machines using S2/S4 flow cells. Sequencing and
     genotyping was performed across nine batches (WES1 through
     WES9) at the Regeneron Genetics Center (RGC) and integrated
     together for this data release. All sequencing batches were
     processed using the same DNA extraction methods and sequencing
     machines, however two different exome capture panels were used,
     as described below. Genotyping was performed using a SNP
     genotyping array for WES1 through WES4 and using
     &quot;genotyping-by-sequencing&quot; (GxS) for WES5 through WES9. The
     first four sequencing batches were sequenced at Regeneron using
     custom NEB/Kapa reagents with the IDT (Integrated DNA
     Technologies) xGen capture platform, including custom exome
     capture regions. Samples starting with batch WES5 were
     sequenced using the Twist Bioscience Human
     Comprehensive Exome panel, combined with spike-ins for
     sequencing genotyping sites (see Genotyping Methods), the full
     mitochondrial genome, and coverage boosted at selected sites
     for assaying clonal hematopoiesis of indeterminate potential
     (CHIP). SFARI performed SNV/indel calling via DeepVariant and
     GATK to generate gVCFs, pairwise relatedness inferred using
     PLINK v1.9 IBD estimates from common SNPs (AF &ge; 0.01, dbSNP
     v151) with &ge;15% relatedness flagged, and comprehensive
     individual- and family-level quality control executed using the
     internal GenomeCheckMate pipeline to exclude samples based on
     contamination (&ge;5%), insufficient coverage (&lt;20x in &lt;80% of
     targets), sex discordance, pedigree/IBD inconsistencies,
     unregistered relationships, unexpected duplicates, or excess
     relatedness, after which QC-passing individuals (selecting the
     most recent passing sample per person) were retained for
     variant calling and joint genotyping.
