Disease characteristics

Excerpted from the GeneReview: Perrault Syndrome

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.

Additional description

From OMIM
Perrault syndrome-6 (PRTLS6) is an autosomal recessive disorder characterized by sensorineural deafness in both males and females, with females also presenting with ovarian dysgenesis resulting in amenorrhea and infertility (summary by Chatzispyrou et al., 2017). http://www.omim.org/entry/617565

Clinical features

From HPO

Premature ovarian insufficiency

MedGen UID:: 9963
•Concept ID:: C0025322
•: Disease or Syndrome

Amenorrhea due to loss of ovarian function before the age of 40. Primary ovarian inssuficiency (POI) is a state of female hypergonadotropic hypogonadism. It can manifest as primary amenorrhea with onset before menarche or secondary amenorrhea.

Streak ovary

MedGen UID:: 78597
•Concept ID:: C0266371
•: Congenital Abnormality

A developmental disorder characterized by the progressive loss of primordial germ cells in the developing ovaries of an embryo, leading to hypoplastic ovaries composed of wavy connective tissue with occasional clumps of granulosa cells, and frequently mesonephric or hilar cells.
