lrg-refseq — HL7 International OID Registry
LRG is a manually curated record that contains stable and thus, un-versioned reference sequences designed specifically for reporting sequence variants with clinical implications. It provides a genomic DNA sequence representation of a single gene that is idealized, has a permanent ID (with no versioning), and core content that never changes. Their database includes maps to NCBI, Ensemble and USCS reference sequences. It has a total of 1073 sequences, as of April 2016 with identifiers of the form: "LRG_####", where #### can be from 1 to N, and N is the last gene processed. See PMIDs: 24285302, 20398331, 20428090 for more information.
