 Structural variants from Oxford Nanopore long-read sequencing of post-mortem
 brain tissue (prefrontal cortex) from 351 individuals, generated by the NIH
 Center for Alzheimer's and Related Dementias (NIH CARD) Long-Read Initiative
 (Billingsley et al. 2024). These are population brain-tissue cohorts with no
 Alzheimer's disease cases. The cohort combines 205 European-ancestry samples
 (North American Brain Expression Consortium, NABEC) and 146 African /
 African-admixed samples (NIMH Human Brain Collection Core, HBCC). ~229k SVs
 (insertions, deletions, inversions) with per-cohort allele counts and allele
 frequencies.

 <h3><a href="hgTrackUi?g=decodeSv">deCODE 3,622 SVs</a></h3>
 <p>
 High-confidence structural variants from 3,622 Icelanders (deCODE genetics),
 sequenced with Oxford Nanopore long reads. ~134k SVs (deletions, insertions
-and combined insertion/deletion events). Site-only callset with annotated
+and combined insertion/deletion events). The callset came without allele counts, so AC=0 
+for all variants.
+Most likely some filtering has been applied, so only calls that appear more than once
+are included in this dataset. Site-only callset with annotated
 surrounding tandem-repeat regions.

 Includes allele frequencies and per-sample support.
