UBAP2L
Chr 1ADubiquitin associated protein 2 like
Also known as: NEDLBF, NICE-4, NICE4
UBAP2L encodes a protein that regulates stress granule assembly, recruits ubiquitination machinery to RNA polymerase II for DNA damage response, and is required for proper brain development and neocortex lamination. Mutations cause autosomal recessive neurodevelopmental disorders affecting brain development. This gene is highly constrained against loss-of-function variants, indicating that such mutations are likely to be pathogenic.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Among the most LoF-intolerant genes (~top 3%)
Highly missense-constrained (top ~0.1%)
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.
