Genes affected

BLOC1S5-TXNDC5 (HGNC:42001): (BLOC1S5-TXNDC5 readthrough (NMD candidate)) This locus represents naturally occurring read-through transcription between the neighboring MUTED (muted homolog) and TXNDC5 (thioredoxin domain containing 5) genes on chromosome 6. The read-through transcript is a candidate for nonsense-mediated mRNA decay (NMD) and is unlikely to produce a protein product. [provided by RefSeq, Dec 2010]
