Perrault syndrome (MIM 233400) is an autosomal recessive disorder that is clinically and genetically heterogeneous and characterized by hearing loss in males and females and premature ovarian failure (POF) (for a review, see Jenkinson et al., 2012).                
*Affected males would be categorized as having nonsyndromic deafness. In the case of mutations of CLPP, one of three mutant alleles (c.270+4A>G) is a leaky splice site mutation and appears to only cause nonsyndromic deafness DFNB81 in females as well, although clinical data for the family segregating c.270+4A>G was sparse (Jenkinson et al., 2013).
