U2SURP
Chr 3U2 snRNP associated SURP domain containing
Also known as: SR140, fSAPa
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Among the most LoF-intolerant genes (~top 3%)
Highly missense-constrained (top ~0.1%)
This gene — mechanism propensity
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.
