GPRIN1
Chr 5G protein regulated inducer of neurite outgrowth 1
Also known as: GRIN1
GPRIN1 encodes a protein that binds phosphoproteins and is involved in neurite outgrowth and neuron projection development at the growth cone and plasma membrane. Mutations cause autosomal recessive neurodevelopmental disorders with intellectual disability and developmental delay. This gene is highly constrained against loss-of-function mutations (pLI 0.97, LOEUF 0.32), indicating that complete loss of protein function is typically not tolerated.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Highly LoF-intolerant (top ~10% of genes)
Mild missense constraint
The highest-scoring mechanism for this gene is loss-of-function (haploinsufficiency).
Predictions from Badonyi M, Marsh JA. PLoS ONE. 2024;19(8):e0307312. Mechanism ranking also informed by gnomAD constraint, ClinVar, and ClinGen data.
