Dear Neelima,
Thank you for using the UCSC Genome Browser and your inquiry about constitutive human exons in the hg19 human assembly.
In summary, we do not have any tables that classify exons as constitutive or alternatively spliced, but you can take further steps to extract this information as referenced in the above archived response.
Thank you again for your inquiry and using the UCSC Genome Browser. If you have further questions, please feel free to contact the mailing list again at
gen...@soe.ucsc.edu.
All the best,
Brian Lee
