ADGRL4

Chr 1

adhesion G protein-coupled receptor L4

Also known as: ELTD1, ETL, KPG_003

NCBI Gene: 64123ENSG00000162618UniProt: Q9HBW9

The protein is an endothelial orphan G protein-coupled receptor that regulates angiogenesis through adenylate cyclase-activating signaling pathways. The gene shows extremely low constraint against loss-of-function variants (pLI near zero), and specific disease associations with ADGRL4 mutations have not been established in pediatric neurogenetic disorders. Further research is needed to determine if mutations in this gene cause recognizable clinical phenotypes.

This gene has evidence for multiple mechanisms of pathogenicity (dominant-negative and gain-of-function). Both the Badonyi & Marsh prediction and the broader genomic evidence point to dominant-negative as the predominant mechanism. Different variants in this gene may act through different mechanisms — interpret in context of the specific variant.

GOFprediction above median

Note: In-silico variant effect predictors (SIFT, PolyPhen, REVEL, CADD) may underestimate pathogenicity of missense variants in genes with GOF or DN mechanisms. Consider functional evidence and clinical context.
