Genes affected

DCAF17 (HGNC:25784): (DDB1 and CUL4 associated factor 17) This gene encodes a nuclear transmembrane protein that associates with cullin 4A/damaged DNA binding protein 1 ubiquitin ligase complex. Mutations in this gene are associated with Woodhouse-Sakati syndrome. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Sep 2009]

DCAF17 links:

METTL8 (HGNC:25856): (methyltransferase 8, tRNA N3-cytidine) Enables mRNA methyltransferase activity. Involved in mRNA methylation. Predicted to be located in cytoplasm and nucleus. [provided by Alliance of Genome Resources, Apr 2022]
