Genes affected

CFAP298 (HGNC:1301): (cilia and flagella associated protein 298) This gene encodes a protein that plays a critical role in dynein arm assembly and motile cilia function. Mutations in this gene result in primary ciliary dyskinesia. Naturally occuring readthrough transcription occurs from this locus to the downstream t-complex 10 like (TCP10L) gene. [provided by RefSeq, Apr 2017]

CFAP298 links:

CFAP298-TCP10L (HGNC:54636): (CFAP298-TCP10L readthrough) This locus represents naturally occurring readthrough transcription between the neighboring chromosome 21 open reading frame 59 (C21orf59) and TCP10L (t-complex 10 like) genes on chromosome 21. Readthrough transcripts may encode a fusion protein that shares sequence identity with each individual gene product. [provided by RefSeq, Apr 2017]
