Genes affected
SYS1 (HGNC:16162): (SYS1 golgi trafficking protein) SYS1 forms a complex with ADP-ribosylation factor-related protein ARFRP1 (MIM 604699) and targets ARFRP1 to the Golgi apparatus (Behnia et al., 2004 [PubMed 15077113]).[supplied by OMIM, Aug 2009]
SYS1-DBNDD2 (HGNC:33535): (SYS1-DBNDD2 readthrough (NMD candidate)) This locus represents naturally occurring read-through transcription from the neighboring SYS1 Golgi-localized integral membrane protein homolog and dysbindin domain containing 2 (DBNDD2) genes. The read-through transcript includes the majority of exons from each individual gene, but it would be subject to nonsense-mediated mRNA decay (NMD) and is therefore predicted to be non-coding.
