Hi Laura,

We have not rebuilt any of our tracks with the RCRS chrM for hg19.  This 
includes the calculations of the phylop scores.  All tracks use the old 
version (NC_001807).

There is a note about it on our hg19 gateway page 
(http://genome.ucsc.edu/cgi-bin/hgGateway?db=hg19):

Note on chrM
Since the release of the UCSC hg19 assembly, the Homo sapiens 
mitochondrion sequence (represented as "chrM" in the Genome Browser) has 
been replaced in GenBank with the record NC_012920. We have not replaced 
the original sequence, NC_001807, in the hg19 Genome Browser. We plan to 
use the Revised Cambridge Reference Sequence (rCRS) in the next human 
assembly release.

If you have further questions, please contact us again at 
[email protected].
