Genes affected

AGAP6 (HGNC:23466): (ArfGAP with GTPase domain, ankyrin repeat and PH domain 6) Predicted to enable GTPase activator activity and metal ion binding activity. Predicted to be involved in regulation of catalytic activity. Predicted to be active in nucleus. [provided by Alliance of Genome Resources, Apr 2022]

TIMM23B-AGAP6 (HGNC:45009): (TIMM23B-AGAP6 readthrough (NMD candidate)) This locus represents naturally-occurring readthrough transcription between the adjacent TIMM23B (translocase of inner mitochondrial membrane 23 homolog B) and AGAP6 (ArfGAP with GTPase domain, ankyrin repeat and PH domain 6) genes. Readthrough transcripts contain portions of the coding sequence for both genes and are predicted to be candidates for nonsense-mediated decay (NMD). [provided by RefSeq, Sep 2018]

ENSG00000285803 (HGNC:):
