UBFD1

Chr 16

ubiquitin family domain containing 1

Also known as: UBPH

UBFD1 encodes a protein that binds RNA and cadherins and may regulate NF-kappa-B signaling. Mutations cause neurodevelopmental disorders with intellectual disability, and the gene shows autosomal recessive inheritance. This gene is highly constrained against loss-of-function variation (pLI 0.94, LOEUF 0.35), indicating intolerance to protein-disrupting mutations.

Clinical SummaryUBFD1
Population Constraint (gnomAD)
Highly constrained gene — heterozygous loss-of-function variants are very rare in the population (pLI 0.94). One damaged copy is likely sufficient to cause disease.
