This syndrome is characterized by the association of congenital mixed hearing loss with perilymphatic gusher (Gusher syndrome or DFN3; see this term), hypogonadism and abnormal behavior.
It has been described in five related males.
Inheritance appeared to be X-linked recessive and a microdeletion, encompassing the POU3F4 gene (DFN3 locus), was detected in one of the patients leading to the suggestion that deafness - hypogonadism is a contiguous gene deletion syndrome.
