> Dear UCSC Curators,
> 
> We have been examining the mapping of various transcript models of TNNT2 and
> appear to have uncovered a mapping error of NM_001001432 in the UCSC RefGene
> Track, hg19 build. The track lists block 3 as mapping to a genomic region
> lacking splice donor and acceptor sites and to be inconsistent with other
> transcript models with similar mRNA sequence such as NM_000364. This appears
> to be due to a mismapping of the 5' GG of block 3 which is correctly mapped in
> NM_000364 but is broken across blocks 2 and 3 in NM_001001432. We have
> included a diagram of this phenomenon below. Blue denotes exonic sequence,
> cyan denotes the mismapped GG, and pink denotes the splice recognition
> locations.
> 
> We bring this to your attention so that you may evaluate the mapping of the
> transcript yourself and a correction be made, if warranted. Please let us know
> if you require additional information.

> Thank you,
