DDX59

Chr 1AR

DEAD-box helicase 59

Also known as: OFD5, ZNHIT5

DDX59 encodes an RNA helicase that binds mRNA and is located in the cytoplasm, membrane, and nucleus. Mutations cause orofaciodigital syndrome V, which affects craniofacial development and digit formation. The gene follows autosomal recessive inheritance and is not highly constrained against loss-of-function variants.

Population Constraint (gnomAD)
Low constraint (pLI 0.00) — loss-of-function variants are relatively tolerated in the population.
