The Northern white-cheeked gibbon (Nomascus leucogenys) genome of a wild-born female named 'Asia' (international studbook #0098) was sequenced to 5.6x whole genome coverage. The sequencing was provided by The Baylor College of Medicine Human Genome Sequencing Center, and the Genome Center at Washington University using Sanger methods. The sequencing method combined whole genome shotgun plasmid, fosmid and BAC end sequences.
The sequence was assembled at The Broad Institute of Harvard and MIT using the Arachne Assembler and assisted with the Human NCBI36 assembly. This draft sequence assembly submitted to Genbank is referred to as Nleu1.0 (GCA_000146795.1).
Funding for the sequencing of the Nomascus leucogenys genome was provided by the National Human Genome Research Institute (NHGRI), National Institutes of Health (NIH).
The N50 size is the median sequence length, i.e. 50% of the assembled genome lies in blocks of the N50 size or longer. The N50 size of the contigs is 35.1 kb. The total length of all contigs is 2.76 Gb. When the gaps between contigs in scaffolds are included, the total span of the assembly is 2.88 Gb.
The genome assembly represented here corresponds to GenBank Assembly ID GCA_000146795.1
The gene set for gibbon was built using the Ensembl gene annotation pipeline. Species-specific resources for gibbon are very limited and therefore sequences from human were used as supporting evidence for coding transcript models: Gibbon and human proteins were mapped to the genome using Genewise. Gibbon cDNAs, human cDNAs and human Ensembl translations from e!61 were mapped to the genome using Exonerate. In addition to the coding transcript models, non-coding RNAs and pseudogenes were also annotated.
General information about this species can be found in Wikipedia.

|Golden Path Length|
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).

Genes and/or transcript that contains an open reading frame (ORF).
|Small non coding genes|
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 ncRNA pipeline. 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.
A pseudogene shares an evolutionary history with a functional protein-coding gene but it has been mutated through evolution to contain frameshift and/or stop codon(s) that disrupt the open reading frame.
