DLX4
Chr 17ADdistal-less homeobox 4
Also known as: BP1, DLX7, DLX8, DLX9, OFC15
The DLX4 protein is a homeobox transcription factor that functions in palatogenesis during embryonic development and may act as a repressor of beta-globin gene expression. Mutations cause orofacial cleft 15, inherited in an autosomal dominant pattern. The pathogenic mechanism likely involves disrupted transcriptional regulation of genes required for normal palatal development.

Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Highly tolerant — LoF variants common in population
Tolerant to missense variation
This gene has evidence for multiple mechanisms of pathogenicity (dominant-negative and loss-of-function). Both the Badonyi & Marsh prediction and the broader genomic evidence point to dominant-negative as the predominant mechanism. Different variants in this gene may act through different mechanisms — interpret in context of the specific variant.
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.
