Perrault syndrome is characterized by sensorineural hearing loss (SNHL) in males and females and ovarian dysfunction in females. SNHL is bilateral and ranges from profound with prelingual (congenital) onset to moderate with early-childhood onset. When onset is in early childhood, hearing loss can be progressive. Ovarian dysfunction ranges from gonadal dysgenesis (absent or streak gonads) manifesting as primary amenorrhea to primary ovarian insufficiency (POI) defined as cessation of menses before age 40 years. Fertility in affected males is reported as normal (although the number of reported males is limited). Neurologic features described in some individuals with Perrault syndrome include learning difficulties and developmental delay, cerebellar ataxia, and motor and sensory peripheral neuropathy. [from GeneReviews]

46,XX gonadal dysgenesis (46,XX GD) is a primary ovarian defect leading to premature ovarian failure (POF; see this term) in otherwise normal 46,XX females as a result of failure of the gonads to develop or due to resistance to gonadotrophin stimulation. [from ORDO]

A type of hearing impairment in one or both ears related to an abnormal functionality of the cochlear nerve. [from HPO]

A partial or complete loss of hearing in one or both ears. It is classified as conductive, sensory, or central. [from NCI]

A decreased magnitude of the sensory perception of sound. [from HPO]

A congenital disorder characterized by the presence of extremely hypoplastic gonads preventing the development of secondary sex characteristics. [from NCI]

Conditions affecting individuals with 46,XX karyotype characterized by atypical development of one or more of the following: the gonads, the internal reproductive structures, the external reproductive/genital structures. [from NCI]

A disorder characterized by the partial or complete loss of the ability to detect sounds due to damage to the ear structures or inability of the brain to properly interpret or process the auditory signals it receives from the anatomic structures of the ear. [from NCI]

The presence of any abnormality of the genitourinary system. [from HPO]

A condition consisting of possessing the internal reproductive organs of one sex while exhibiting some of the secondary sex characteristics of the opposite sex. [from NCI]

A non-neoplastic or neoplastic disorder that affects the ear. Representative examples include infections, hearing disorders, benign neoplasms, and carcinomas. [from NCI]

Hypergonadotropic ovarian failure is a heterogeneous disorder that, in the most severe forms, is a result of ovarian dysgenesis. Ovarian dysgenesis accounts for about half the cases of primary amenorrhea (Timmreck and Reindollar, 2003). Genetic Heterogeneity of Ovarian Dysgenesis Even in its isolated form, 46,XX ovarian dysgenesis is etiologically heterogeneous. See ODG2 (300510), caused by mutation in the BMP15 gene (300247); ODG3 (614324), caused by mutation in the PSMC3IP gene (608665); ODG4 (616185), caused by mutation in the MCMDC1 gene (610098); ODG5 (617690), caused by mutation in the SOHLH1 gene (610224); ODG6 (618078), caused by mutation in the NUP107 gene (607617); ODG7 (618117), caused by mutation in the MRPS22 gene (605810); ODG8 (618187), caused by mutation in the ESR2 gene (601663); ODG9 (619665), caused by mutation in the SPIDR gene (615384); and ODG10 (619834), caused by mutation in the ZSWIM7 gene (614535).
