Genes affected

CFAP184 (HGNC:26900): (cilia and flagella associated protein 184) Predicted to be involved in cilium assembly. Predicted to be active in axoneme and ciliary basal body. [provided by Alliance of Genome Resources, Apr 2022]

CFAP184 links:

TADA2B (HGNC:30781): (transcriptional adaptor 2B) TADA2B functions as a transcriptional adaptor protein that potentiates transcription through coordination of histone acetyltransferase (HAT) activity and by linking activation factors to basal transcriptional machinery (Barlev et al., 2003 [PubMed 12972612]).[supplied by OMIM, Apr 2010]
