The protein is a large secreted extracellular matrix protein that controls cell positioning and neuronal migration during brain development. Mutations cause autosomal recessive lissencephaly type 2 (Norman-Roberts type) with cerebellar hypoplasia and autosomal dominant familial temporal lobe epilepsy type 7. The pathogenic mechanism involves loss of function, disrupting normal neuronal migration patterns.
Definitive — sufficient evidence for diagnostic panels
2 total gene-disease associations curated
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Highly LoF-intolerant (top ~10% of genes)
Moderately missense-constrained (top ~2.5%)
Predictions shown for reference only — model trained on dominant genes, not applicable to AR conditions.
The Badonyi & Marsh prediction model was trained exclusively on dominant disease genes. Predictions are not reliable for genes with autosomal recessive inheritance and are shown at reduced opacity for reference only.
Literature Evidence
Predictions from Badonyi M, Marsh JA. PLoS ONE. 2024;19(8):e0307312. Mechanism ranking also informed by gnomAD constraint, ClinVar, and ClinGen data.
