The Ensembl project explicit aims to predict long intergenic non  
coding RNAs
(lincRNAs) using a similar scheme (ie, histone modification patterns)  
and
ESTs/cDNAs without coding potential in both Human and Mouse. They are  
explicitly
characterised as lincRNAs. Like all our "predictions", they are biased  
towards
a high specificity set and backed up by experimental evidence.

An example one is here:

http://www.ensembl.org/Homo_sapiens/Gene/Summary?db=core;g=ENSG00000245883;r=7:99517494-99522910;t=ENST00000499990


Looking into the corresponding import of Ensembl into UCSC here:

http://genome.ucsc.edu/cgi-bin/hgc?hgsid=173968291&o=99517493&t=99522910&g=ensGene&i=ENST00000499990

This transcript is there, but I can't spot the "biotype" slot here -  
it is just
that it is non coding (we have about ~20 other non coding biotypes,  
eg, snoRNAs,
miRNAs etc)



(Is this true - UCSC guys, would it be possible to get the concept of  
BioType in
the Ensembl set?)


Also the Havana project, which does manual curation, which is both  
merged in a principled
way with the Ensembl set (ie, the Ensembl set is a super-set of Havana  
at the point of
release) and is available in UCSC browser also has a large set of non  
coding RNAs.


A count of lincRNAs in Human and Mouse in Ensembl are:

    1443 - in Human

    407 - in Mouse.


It is probably possible to either download from UCSC and the biotypes  
from Ensembl with
a script to join or of course download the set from ensembl. You might  
like to use
our BioMart tool:
