DEFB124
Chr 20defensin beta 124
Also known as: DEFB-24
The DEFB124 protein is an antimicrobial beta defensin that provides antibacterial activity and enhances innate immunity, particularly in the prostate. Currently, no established pediatric neurological disorders are associated with mutations in this gene. This gene is not highly constrained against loss-of-function variants, suggesting tolerance to functional disruption.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Highly tolerant — LoF variants common in population
Mild missense constraint
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.
