VENT homeobox

Also known as: HPX42B, NA88A, VENTX2

The protein is a homeodomain transcription factor that functions as a transcriptional repressor involved in mesodermal patterning and hematopoietic stem cell maintenance. Mutations cause autosomal dominant neurodevelopmental disorder with seizures, microcephaly, cortical malformations, and dysmorphic facies. This gene is not highly constrained against loss-of-function variants, suggesting complete loss of function may be tolerated.

Population Constraint (gnomAD)
Low constraint (pLI 0.00) — loss-of-function variants are relatively tolerated in the population.

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.
