GTEx Get Gene Expression

Get gene expression data at individual sample level (not aggregated). Returns normalized expression values (TPM) for each sample, allowing detailed distribution analysis. Can subset by donor attributes (sex, age_bracket) for demographic-specific analysis. Much more data than median expression. Use for: expression variability analysis, outlier detection, sample-level QC, demographic comparisons. Warning: large result sets for multiple genes/tissues.
