Genes affected
BTBD18 (HGNC:37214): (BTB domain containing 18) Predicted to be involved in several processes, including male gamete generation; piRNA biosynthetic process; and positive regulation of transcription elongation from RNA polymerase II promoter. Predicted to be active in nucleus. [provided by Alliance of Genome Resources, Apr 2022]
TMX2-CTNND1 (HGNC:41992): (TMX2-CTNND1 readthrough (NMD candidate)) This locus represents naturally occurring read-through transcription between the neighboring TMX2 (thioredoxin-related transmembrane protein 2) and CTNND1 (catenin, cadherin-associated protein, delta 1) genes on chromosome 11. The read-through transcript is a candidate for nonsense-mediated mRNA decay (NMD), and is therefore unlikely to produce a protein product. [provided by RefSeq, Dec 2010]
