Genes affected
TBC1D26 (HGNC:28745): (TBC1 domain family member 26) Predicted to enable GTPase activator activity. Predicted to be involved in activation of GTPase activity and intracellular protein transport. [provided by Alliance of Genome Resources, Apr 2022]
ZNF286A-TBC1D26 (HGNC:55384): (ZNF286A-TBC1D26 readthrough (NMD candidate)) This locus represents naturally occurring read-through transcription between the neighboring ZNF286A and TBC1D26 genes. This transcript is thought to be non-coding because it would be subject to nonsense-mediated mRNA decay (NMD). [provided by RefSeq, Nov 2020]
TBC1D26-AS1 (HGNC:41211): (TBC1D26 antisense RNA 1)
