From OMIMDeafness-infertility syndrome (DIS), characterized by early-onset deafness in both males and females and exclusive male infertility, is caused by homozygous deletion of the STRC and CATSPER2 genes on chromosome 15q15.5 (summary by Vona et al., 2015).
http://www.omim.org/entry/611102 From MedlinePlus GeneticsSensorineural deafness and male infertility is a condition characterized by hearing loss and an inability to father children. Affected individuals have moderate to severe sensorineural hearing loss, which is caused by abnormalities in the inner ear. The hearing loss is typically diagnosed in early childhood and does not worsen over time. Males with this condition produce sperm that have decreased movement (motility), causing affected males to be infertile.
