The March 2006 human reference sequence (NCBI Build 36.1) was produced by the International Human Genome Sequencing Consortium. For more information about this assembly, see NCBI36 in the NCBI Assembly database.
A genome position can be specified by the accession number of a sequenced genomic clone, an mRNA or EST or STS marker, or a cytological band, a chromosomal coordinate range, or keywords from the GenBank description of an mRNA. The following list shows examples of valid position queries for the human genome. See the User's Guide for more information.

|
chr7 | Displays all of chromosome 7 | |
20p13 | Displays region for band p13 on chr 20 | |
chr3:1-1000000 | Displays first million bases of chr 3, counting from p-arm telomere | |
chr3:1000000+2000 | Displays a region of chr3 that spans 2000 bases, starting with position 1000000 | |
RH18061;RH80175 15q11;15q13 |
Displays region between STS markers RH18061 and RH80175 or chromosome bands 15q11 to 15q13. This syntax may also be used for other range queries, such as between uniquely determined ESTs, mRNAs, refSeqs, etc. | |
D16S3046 | Displays region around STS marker D16S3046 from the Genethon/Marshfield maps. Includes 100,000 bases on each side as well. | |
AA205474 | Displays region of EST with GenBank accession AA205474 in BRCA1 cancer gene on chr 17 | |
AC008101 | Displays region of clone with GenBank accession AC008101 | |
AF083811 | Displays region of mRNA with GenBank accession number AF083811 | |
PRNP | Displays region of genome with HUGO Gene Nomenclature Committee identifier PRNP | |
NM_017414 | Displays the region of genome with RefSeq identifier NM_017414 | |
NP_059110 | Displays the region of genome with protein accession number NP_059110 | |
pseudogene mRNA | Lists transcribed pseudogenes, but not cDNAs | |
homeobox caudal | Lists mRNAs for caudal homeobox genes | |
zinc finger | Lists many zinc finger mRNAs | |
kruppel zinc finger | Lists only kruppel-like zinc fingers | |
huntington | Lists candidate genes associated with Huntington's disease | |
zahler | Lists mRNAs deposited by scientist named Zahler | |
Evans,J.E. | Lists mRNAs deposited by co-author J.E. Evans | |
Use this last format for author queries. Although GenBank requires the search format Evans JE, internally it uses the format Evans,J.E.. |
The NCBI Build 36.1 reference sequence is considered to be "finished", a technical term indicating that the sequence is highly accurate (with fewer than one error per 10,000 bases) and highly contiguous (with the only remaining gaps corresponding to regions whose sequence cannot be reliably resolved with current technology). Future work on the reference sequence will focus on improving accuracy and reducing gaps in the sequence. Statistics for the Build 36.1 assembly can be found on the NCBI Build 36.1 Statistics web page.
This assembly contains four alternate haplotype regions:
See the Wellcome Trust Sanger Institute MHC Haplotype Project web site for additional information on the chr6 alternate haplotype assemblies.
The Y chromosome in this assembly contains two pseudoautosomal regions (PARs) that were taken from the corresponding regions in the X chromosome and are exact duplicates:
chrY:1-2709520 and chrY:57443438-57772954
chrX:1-2709520 and chrX:154584238-154913754
