KIZ antisense RNA 1 (KIZ-AS1)

Target: KIZ-AS1
Molecular classification: Long non-coding RNA (lncRNA), Antisense RNA, Other

Overview

KIZ antisense RNA 1 (KIZ-AS1) is a long non-coding RNA (lncRNA) transcribed antisense to the protein-coding KIZ (Kizuna centrosomal protein) gene locus on chromosome 20[1][3][5]. KIZ-AS1 does not encode a protein but likely regulates the expression of KIZ or potentially adjacent genes via RNA-mediated mechanisms typical of antisense lncRNAs (including modulation of transcription, mRNA stability, or chromatin state)[2][3][4]. Its specific molecular effects remain undetermined. KIZ-AS1 has been identified as significantly associated with autism spectrum disorder in genome-wide studies, suggesting possible involvement in neurodevelopmental regulation, but its function in disease or normal biology is not defined and there are no drugs or clinical interventions targeting it to date[1][3][5].

Mechanism of action

Not applicable; as an endogenous lncRNA, KIZ-AS1 is not currently a drug target; there are no reported drugs or experimental molecules targeting it specifically.

Biological functions

Putative regulation of gene expression at the RNA level through antisense interaction with KIZ mRNA or its locus[1][2][3].

Disease associations

Autism spectrum disorder (significantly associated in GWAS and multi-omics data)[1][3][5]Glioma susceptibility 1 (associative database link; mechanistic relation unproven)[3]Atypical autism (as above)[3]

Safety considerations

Not applicable; there are no reported safety issues or therapeutic challenges as KIZ-AS1 is not targeted by drugs.

Biomarkers

None validated specifically; KIZ-AS1 has been suggested as a gene region of interest in autism genetics, but not established as a clinical biomarker[1][5].
