Description
Parse an explicit exon/intron ordinal token without genomic boundary inference.
Pharmacogenomic records distinguish allele labels, copy counts, reference-sequence versions, coordinate systems, and evidence about chromosome phase. A balanced count or matching token can check a record without establishing the underlying genotype. Supplied activity values and interpretation rules remain separate from a current gene-specific clinical guideline.
Parse an explicit exon/intron ordinal token without genomic boundary inference.
When to use this tool
Use Pharmacogene Exon Intron Boundary Token when you need this specific allele-token, reference-coordinate, copy-budget, or source-support check.
How to use the tool and how it works
- Enter token. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read kind, index. Use the output convention below.
Accept exactly exon: or intron: followed by a positive safe-integer index; return kind and index.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| token | Complete literal token in the grammar stated above. | Required. Text; maximum UTF-16 length 8192. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| kind | Kind | Required. Text; maximum UTF-16 length 8192. |
| index | Index in the convention explicitly stated in the mechanics. | Required. Safe integer. |
{
"input": {
"token": "exon:3"
},
"output": {
"kind": "exon",
"index": 3
}
}Limitations and assumptions
- Matching is lowercase and whitespace-sensitive. No transcript, exon numbering convention, actual feature existence, or variant position is checked.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
Alternative or Complementary methods
Use a current gene-specific nomenclature and a validated interpretation process when allele identity, phase, function, or clinical decisions matter. Verify source versions and reference coordinates before combining records.
