<p> The golden path is the length of the reference assembly. It consists of the sum of all top-level sequences in the seq_region table, omitting any redundant regions such as haplotypes and PARs (pseudoautosomal regions). </p>Golden Path Length	4,795,662

<p>Genes and/or transcript that contains an open reading frame (ORF).</p>Coding genes	4,557
Non coding genes	73
<p>Small non coding genes are usually fewer than 200 bases long. They may be transcribed but are not translated. In Ensembl, genes with the following biotypes are classed as small non coding genes: miRNA, miscRNA, rRNA, scRNA, snlRNA, snoRNA, snRNA, and also the pseudogenic form of these biotypes. The majority of the small non coding genes in Ensembl are annotated automatically by our <a title="Ensembl ncRNA annotation" href="/info/genome/genebuild/ncrna.html">ncRNA pipeline</a>. Please note that tRNAs are annotated separately using tRNAscan. tRNAs are included as 'simple fetaures', not genes, because they are not annotated using aligned sequence evidence.</p>Small non coding genes	73
Nucleotide sequence resulting from the transcription of the genomic DNA to mRNA. One gene can have different transcripts or splice variants resulting from the alternative splicing of different exons in genes.Gene transcripts	4,630
