[Genome] cytogenetic banding pattern..mouse

[Tereshchenko, Irina]

Hi,
I have question about cytogenetic banding pattern of mouse chromosomes.

I did compare the Ensemble and UCSC dbs. How it possible - to have same size of chromosome, same location of  genes, etc,  and  absolutely different location of cytogenetic bands (that seen on Giemsa-stained chromosomes).

For example, gene Psmd7
Ensemble: Chromosome 8 at location 110,104,281-110,112,382 , Band: 8D2
UCSC: Position: chr8:110104281-110112382 , Band: 8qD3

Cytogenetic bands:

8A1
Ensemble: 2999000-9040477bp (6,041,477bp)
UCSC: 1-16,228,701 bp (16,228,701 bp)

8A3
Ensemble: 16776277-34188325 bp (17,412,048bp)
UCSC: 30,070,830-34,366,662 bp (4,295,832bp)

8D1
Ensemble: 98852223- 107421070 (8,568,847 bp)
UCSC: 97,372,210-105,009,245 (7,637,035 bp)

8E2
Ensemble: 125105471- 131738871 (6,633,400bp)
UCSC:: 126,011,095-131,738,871 (5,727,776bp)

What is it?
