Nucleotide and protein links: why do the nucleotide or protein links at the top of an OMIM record sometimes lead to unrelated genes?
The references listed near the end of an OMIM entry often cite accession numbers of nucleotide or protein sequence records. Those sequence records can contain data for the gene discussed in the OMIM entry, or for other genes that were discussed by the authors of the cited references. The nucleotide and protein links at the top of the OMIM entry will lead to all of the sequence records cited by all of the references. These are referred to as “calculated links,” since they are established in an automated way. On the other hand, the sequence links (e.g., RefSeq, GenBank, Protein, and UniGene) in the blue sidebar of the OMIM entry will lead only to records that contain sequence data for the gene being discussed. These are referred to as “curated links.” Please see the links to related information section of the OMIM Help document for more information about calculated links and curated links.
