Version Compatibility

Reference examples tested with: requests 2.31+, pandas 2.2+

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.

gnomAD Frequency Queries

gnomAD REST API

Goal: Retrieve exome and genome allele frequencies from gnomAD for individual variants.

Approach: Send a GraphQL query to the gnomAD API with variant ID and dataset version, then parse exome/genome frequency fields.
