Genes affected

CCDC180 (HGNC:29303): (coiled-coil domain containing 180) The protein encoded by this gene contains a coiled-coil domain. Alternative splicing results in multiple transcript variants encoding different isoforms. A single nucleotide polymorphism (SNP) in this gene has been associated with increased susceptibility to Behcet's Disease (PMID: 19442274). [provided by RefSeq, Dec 2016]

CCDC180 links:

SUGT1P4-STRA6LP-CCDC180 (HGNC:53835): (SUGT1P4-STRA6LP-CCDC180 readthrough) This locus represents a set of read-through transcripts spanning an upstream pseudogene (GeneID:100499484) extending into a downstream protein-coding locus (GeneID:100499483). All of the read-through transcripts are candidates for nonsense-mediated decay (NMD), so they are not thought to express a protein. [provided by RefSeq, Aug 2010]
