HES3

Chr 1

hes family bHLH transcription factor 3

Also known as: bHLHb43

The HES3 protein functions as a transcriptional repressor that inhibits genes requiring basic helix-loop-helix (bHLH) proteins for transcription and is predicted to regulate neurogenesis and nervous system development. Currently, no established human diseases have been definitively linked to HES3 mutations in the medical literature. The gene shows relatively low constraint against loss-of-function variants (pLI = 0.28, LOEUF = 1.25), suggesting it may be more tolerant to genetic variation than highly disease-associated genes.

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.
