[5][6][7] Defensins form a family of microbicidal and cytotoxic peptides made by neutrophils.

All beta-defensin genes are densely clustered in four to five syntenic chromosomal regions.

Chromosome 8p23 contains at least two copies of the duplicated beta-defensin cluster.

This duplication results in two identical copies of defensin, beta 105, DEFB105A and DEFB105B, in tail-to-tail orientation.
