SMURF2

Chr 17

SMAD specific E3 ubiquitin protein ligase 2

Enables SMAD binding activity; identical protein binding activity; and ubiquitin protein ligase activity. Involved in negative regulation of transforming growth factor beta receptor signaling pathway; positive regulation of trophoblast cell migration; and ubiquitin-dependent protein catabolic process. Located in nuclear speck. Part of ubiquitin ligase complex. [provided by Alliance of Genome Resources, Jul 2025]

Clinical SummarySMURF2
Population Constraint (gnomAD)
Moderately constrained gene (pLI 0.87) — some intolerance to loss-of-function variants.

Population Genetics & Constraint

gnomAD v4 — loss-of-function & missense intolerance

LoF intolerant — likely haploinsufficient
LoF Constraint?LOEUF (Loss-of-function Observed/Expected Upper bound Fraction) is the upper bound of the 90% CI for LoF OE — the preferred gnomAD v4 metric. Lower = more intolerant to LoF. LOEUF < 0.35 = highly constrained.

pLI 0.872

OE 0.20 (0.120.33)
Highly constrained

Highly LoF-intolerant (top ~10% of genes)

Missense Constraint?Missense Z-score: standard deviations fewer missense variants observed vs. expected. Z > 3.09 (p < 0.001) = gene does not tolerate missense variation. OE missense < 0.6 is also considered constrained.
