DESCRIPTION
This parser returns Bio::Phenotype::OMIM::OMIMentry objects (which inherit from Bio::Phenotype::PhenotypeI). It parses the OMIM database available as ftp://ncbi.nlm.nih.gov/repository/OMIM/omim.txt.Z together with (optionally) the gene map file at ftp://ncbi.nlm.nih.gov/repository/OMIM/genemap.

FEEDBACK

  Mailing Lists
User feedback is an integral part of the evolution of this and other Bioperl modules. Send your comments and suggestions preferably to the Bioperl mailing lists Your participation is much appreciated.

  Support
Please direct usage questions or support issues to the mailing list:

bioperl-l@bioperl.org

rather than to the module maintainer directly. Many experienced and reponsive experts will be able look at the problem and quickly address it. Please include a thorough description of the problem with code and data examples if at all possible.
