Genes affected

ZNF286A (HGNC:13501): (zinc finger protein 286A) Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Predicted to be involved in regulation of transcription by RNA polymerase II. Predicted to be integral component of membrane. Predicted to be active in nucleus. [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]

ACMG classification
