chr1100000100500

chr1100000100500 is a genomic identifier constructed with the "chr" prefix, commonly used in bioinformatics to denote chromosome-associated features. It is not a standard identifier in major public genome resources, and there is no established record linking this exact label to a known chromosome, gene, or coordinate in assemblies such as GRCh38 or GRCh37. Consequently, its meaning depends entirely on the dataset or software that generates it.

In some data schemas, identifiers are created by concatenating chromosome number with start and end coordinates; under such a scheme, a string like chr1100000100500 could encode chromosome 11 with a specific interval, but decoding would require the dataset’s specification. In other contexts, the string may function as a unique key without any embedded positional information, used to reference a synthetic feature in benchmarking, test datasets, or internal catalogs.

Practical notes: When encountering chr1100000100500 in a file, researchers should check the accompanying metadata, data dictionary, or schema documentation to determine its intended meaning. If the identifier appears in a variant call or annotation pipeline, ensure compatibility with tools that expect standard coordinates or IDs and avoid assuming a literal biological interpretation.

Overall, chr1100000100500 illustrates how registry-specific keys can differ from widely adopted genomic nomenclature, and it underscores the importance of dataset documentation for interpretation.
