Gnomad Get Constraint

Get gene-level constraint metrics from gnomAD (Genome Aggregation Database) for a single gene, given a gene symbol (e.g. BRCA1) OR an Ensembl gene ID (e.g. ENSG00000012048). Returns a flat, curated summary: pLI (probability of loss-of-function intolerance), oe_lof (observed/expected LoF ratio) with its lower/upper confidence bounds, LOEUF (= oe_lof_upper, the recommended constraint metric; lower = more constrained), missense Z-score (mis_z), synonymous Z-score (syn_z), and expected/observed LoF…

Overview

Get gene-level constraint metrics from gnomAD (Genome Aggregation Database) for a single gene, given a gene symbol (e.g. BRCA1) OR an Ensembl gene ID (e.g. ENSG00000012048). Returns a flat, curated summary: pLI (probability of loss-of-function intolerance), oe_lof (observed/expected LoF ratio) with its lower/upper confidence bounds, LOEUF (= oe_lof_upper, the recommended constraint metric; lower = more constrained), missense Z-score (mis_z), synonymous Z-score (syn_z), and expected/observed LoF counts (exp_lof, obs_lof). The `dataset` parameter selects the constraint release: gnomad_r4 (default) and gnomad_r3 use GRCh38 (gnomAD v4 constraint); gnomad_r2_1 and exac use GRCh37. Note: gnomAD uses current HGNC symbols (e.g. GBA1, not GBA). No API key required.
