Homozygous inactivation of this gene results in sterility and progressive axonopathy with focal axonal swellings and late onset gait abnormalities. Mice homozygous for a knock-out allele exhibit male sterility, decreased testis weight, azoospermia, defects in male meiosis, acrosome formation and manchette structure, and loss of spermatid nuclear integrity.
