Genes affected

DDX54 (HGNC:20084): (DEAD-box helicase 54) This gene encodes a member of the DEAD box protein family. DEAD box proteins, characterized by the conserved motif Asp-Glu-Ala-Asp (DEAD), are putative RNA helicases. They are implicated in a number of cellular processes involving alteration of RNA secondary structure such as translation initiation, nuclear and mitochondrial splicing, and ribosome and spliceosome assembly. Based on their distribution patterns, some members of this family are believed to be involved in embryogenesis, spermatogenesis, and cellular growth and division. The nucleolar protein encoded by this gene interacts in a hormone-dependent manner with nuclear receptors, and represses their transcriptional activity. Alternative splice variants that encode different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

CFAP73 (HGNC:37100): (cilia and flagella associated protein 73) Predicted to enable dynein complex binding activity. Predicted to be involved in cilium movement and inner dynein arm assembly. Predicted to be located in axonemal outer doublet and motile cilium. [provided by Alliance of Genome Resources, Apr 2022]
