<h2>Description</h2>
<p>
Ensembl genes annotations of the HPRC assemblies, version: $ebiVersion
on the $assemblyDate $em${organism}$noEm/$asmId genome assembly.
<br>
$geneCount
</p>

<h2>Methods</h2>
<p>
Ensembl annotation of the human assemblies has been produced via a new
mapping pipeline:<br>
<br>
A subset of the GENCODE 38 genes and transcripts have been annotated on each
of the haploid assemblies. The subset excludes readthrough genes and genes
on patches or haplotypes.  For each gene, anchor sequences built from the
surrounding region were used to locate the most likely corresponding
region(s) in the target genome. A pairwise alignment of the reference and
target regions was then carried out and used to map the exon coordinates and
other features of the gene.  In addition to the primary mapping, potential
recent duplications and collapsed paralogues were identified by aligning
canonical transcripts across the entire genome and searching for new
mappings that did not overlap existing annotations.  For more details on the
annotation process, please refer to the
<a href="https://www.biorxiv.org/content/10.1101/2022.07.09.499321v1" target="_blank">preprint publication</a>
