Comparative genomic study reveals conserved gene order and architectural homology in human and mouse chromosomes, highlighting structural evolutionary conservation.

Key Points

To sequence and analyze orthologous regions of human chromosome 11p15.3 and mouse chromosome 7 to characterize conserved genomic architecture, gene organization, and functional elements.
Sequenced and comparatively evaluated approximately 730 kb of human chromosome 11p15.3 and 620 kb of mouse chromosome 7.
Assessed gene content, transcript orientation, base composition, isochore structure, CpG island distribution, and repetitive element proportions across both species.
Identified 11 genes across the region, displaying conserved order and orientation between species, alongside one human-specific putative gene lacking a mouse counterpart.
Demonstrated matching CpG island distribution and comparable GC isochores (45% GC for H1; 39% human vs. 40% mouse for L1/L2), with an elevated gene density of one gene per 66 kb.
Observed a significantly higher proportion of interspersed repeats in human DNA (43.8%) compared to mouse DNA (30.1%), accounting for the human genomic expansion.
