Version Compatibility

Reference examples tested with: BioPython 1.83+, Entrez Direct 21.0+

Before using code patterns, verify installed versions match. If versions differ:

• Python: pip show <package> then help(module.function) to check signatures

If code throws ImportError, AttributeError, or TypeError, introspect the installed package and adapt the example to match the actual API rather than retrying.

dbSNP Queries

"Look up variant information by rsID" → Retrieve variant annotations, genomic coordinates, and cross-references to ClinVar/gnomAD from dbSNP using REST API queries.

• Python: myvariant.MyVariantInfo().getvariant('rs12345')

Query rsID via myvariant.info

Goal: Retrieve variant information including dbSNP, ClinVar, and gnomAD annotations by rsID.
