LRRC7
Chr 1ADleucine rich repeat containing 7
Also known as: DENSIN, MRD77
The LRRC7 protein is required for normal synaptic spine architecture and function, and is necessary for proper localization of DISC1 and GRM5 to postsynaptic density complexes and for both NMDA receptor-dependent and metabotropic glutamate receptor-dependent long term depression. Mutations cause autosomal dominant intellectual developmental disorder. This gene is highly constrained against loss-of-function variants (pLI = 1.0, LOEUF = 0.157), indicating intolerance to protein-disrupting mutations.

Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Highly LoF-intolerant (top ~10% of genes)
Highly missense-constrained (top ~0.1%)
The highest-scoring mechanism for this gene is loss-of-function (haploinsufficiency).
