ZBTB26

Chr 9

zinc finger and BTB domain containing 26

Also known as: ZNF481, bioref

The protein functions as a transcriptional regulator that binds to specific DNA sequences and negatively regulates RNA polymerase II transcription, with predicted roles in cytokine production and immune system regulation. Currently, no established Mendelian diseases have been definitively linked to ZBTB26 mutations. The gene shows moderate tolerance to loss-of-function variants based on constraint metrics, suggesting that if pathogenic mutations exist, they may cause disease through other mechanisms.

The highest-scoring mechanism for this gene is dominant-negative.

Note: In-silico variant effect predictors (SIFT, PolyPhen, REVEL, CADD) may underestimate pathogenicity of missense variants in genes with GOF or DN mechanisms. Consider functional evidence and clinical context.
