We demonstrate that members of the olfactory receptor (OR) gene family are distributed on all but a few human chromosomes. Through FISH analysis, we show that OR sequences reside at more than 25 locations in the human genome. Their distribution is biased for terminal bands. Flow-sorted chromosomes were used to isolate 87 OR sequences derived from 16 chromosomes. Their sequence-relationships are indicative of the inter- and intrachromosomal duplications responsible for OR family expansion. The human genome has accumulated a striking number of dysfunctional copies: 72% of the sequences are pseudogenes. ORF-containing sequences predominate on chromosomes 7, 16 and 17.

SciCrunch is a data sharing and display platform. Anyone can create a custom portal where they can select searchable subsets of hundreds of data sources, brand their web pages and create their community. SciCrunch will push data updates automatically to all portals on a weekly basis. User communities can also add their own data to SciCrunch, however this is not currently a free service.
