Genes affected

IFT80 (HGNC:29262): (intraflagellar transport 80) The protein encoded by this gene is part of the intraflagellar transport complex B and is necessary for the function of motile and sensory cilia. Defects in this gene are a cause of asphyxiating thoracic dystrophy 2 (ATD2). Three transcript variants encoding two different isoforms have been found for this gene.[provided by RefSeq, Jun 2010]

IFT80 links:

TRIM59-IFT80 (HGNC:56756): (TRIM59-IFT80 readthrough (NMD candidate)) This locus represents naturally occurring readthrough transcription between the neighboring TRIM59 (tripartite motif containing 59) and IFT80 (intraflagellar transport 80) genes on chromosome 3. The readthrough transcript is unlikely to produce a protein product. [provided by RefSeq, Jun 2017]
