NETO1
Chr 18neuropilin and tolloid like 1
Also known as: BCTL1, BTCL1
The protein functions as an accessory subunit of neuronal NMDA receptors, maintaining GRIN2A-containing NMDARs in the postsynaptic density and regulating synaptic plasticity critical for spatial learning and memory. Mutations cause autosomal recessive intellectual disability and epileptic encephalopathy with onset in infancy or early childhood. The gene is highly constrained against loss-of-function variants (LOEUF 0.496), indicating that complete loss of protein function is likely not tolerated.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
More LoF-intolerant than ~75% of genes
Mild missense constraint
This gene has evidence for multiple mechanisms of pathogenicity (gain-of-function and dominant-negative). Both the Badonyi & Marsh prediction and the broader genomic evidence point to gain-of-function as the predominant mechanism. Different variants in this gene may act through different mechanisms — interpret in context of the specific variant.
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.
