A number sign (#) is used with this entry because of evidence that Perrault syndrome-1 (PRLTS1) is caused by compound heterozygous mutation in the HSD17B4 gene (601860) on chromosome 5q23.
Perrault syndrome is a sex-influenced disorder characterized by sensorineural deafness in both males and females and ovarian dysgenesis in females. Some patients also have neurologic manifestations, including mild mental retardation and cerebellar and peripheral nervous system involvement (summary by Pierce et al., 2010). Pierce et al. (2010) noted that clinical heterogeneity of Perrault syndrome has prompted classification into type I, which is static and without neurologic disease, and type II, which is with progressive neurologic disease.

Perrault et al. (1951) described 2 sisters with a syndrome comprising sensorineural deafness and ovarian dysgenesis. The parents were cousins, suggesting autosomal recessive inheritance. Josso et al. (1963) restudied the sisters reported by Perrault et al. (1951) as adults and showed that both had a normal 46,XX karyotype. Both were deaf-mute and lacked ovaries on laparoscopy. Both sisters had castrate levels of gonadotropins. In addition, the older sister was obese and had a short neck.
McCarthy and Opitz (1985) described 2 sisters from Montana with Perrault syndrome. The girls were ages 15 and 4 years, respectively. Both had early-onset severe sensorineural deafness, and the older girl had delayed pubertal development with low urinary gonadotropin levels. The older sister also had neurologic abnormalities, including delayed motor development and mild spastic diplegia with weakness of the lower limbs, pes cavus, and contracted heel cords. She also had mild dysmorphic facial features. However, she had had a difficult birth, which may have contributed to the neurologic features. The younger sister did not have these extra anomalies. Fiumara et al. (2004) restudied the pair of sisters reported by McCarthy and Opitz (1985). The older sister was found to have electrophysiologic evidence of a peripheral axonal neuropathy as well as cerebellar hypoplasia. Her condition had progressed by her twenties, and she required a wheelchair. Other features included nystagmus on lateral gaze, dysarthria, mild titubation of the head, hyporeflexia, sensory neuropathy, and learning difficulties. The younger sister had also developed similar, but milder, neurologic signs. She had progressive weakness, pes cavus, axonal neuropathy, and ovarian failure with minimal pubertal development. Metabolic and mitochondrial testing were normal. In the sisters with Perrault syndrome and neurologic abnormalities reported by McCarthy and Opitz (1985) and Fiumara et al. (2004), Pierce et al. (2010) identified 2 mutations in the HSD17B4 gene (601860.0008 and 601860.0009).
Perez-Ballester et al. (1970) reported 2 sisters with primary amenorrhea, sexual infantilism, congenital nerve deafness, streak gonads, and 46,XX karyotype. The patients responded well to cyclic estrogen therapy. Bosze et al. (1983) reported affected sisters. In the family reported by Christakos et al. (1969), 2 out of 3 sisters with gonadal dysgenesis and a sexually normal brother had bilateral sensorineural hearing deficits. Two of the girls had mental retardation. The parents were second cousins, suggesting an autosomal recessive condition.
Nishi et al. (1988) described this disorder in 2 Japanese sisters. In addition to ovarian dysgenesis and sensorineural deafness, they had ataxic gait, pes equinovarus, nystagmus, limited extraocular movements, and short stature. The authors' review of the literature included 21 patients from 8 families; 3 deaf males had no gonadal defect, and 1 woman with ovarian dysgenesis had no deafness.
Linssen et al. (1994) presented the cases of 2 brothers and a sister with sensorineural deafness. Ovarian dysgenesis in the sister suggested diagnosis of Perrault syndrome. In addition, the patients had a sensory polyneuropathy and amelogenesis imperfecta. Two had mild mental retardation, fine choreatic movements, and dyspraxia. Linssen et al. (1994) were uncertain as to whether the condition in this family represented a separate clinical entity or could be included within the range of variability of the Perrault syndrome.
Gottschalk et al. (1996) reported a brother and sister with sensorineural deafness; the sister also had ovarian dysgenesis, mental retardation, generalized ataxia of the trunk and limbs, and saccadic dysmetria. A CT scan showed cerebellar hypoplasia. The authors reviewed the 28 reported cases of Perrault syndrome; neurologic data were available for 14 of 21 females, 7 of whom had neurologic abnormalities. Gottschalk et al. (1996) suggested that ataxia or mental retardation may not be coincidental but rather pleiotropic manifestations of Perrault syndrome.
Fiumara et al. (2004) described 2 pairs of sisters, one pair originally reported by McCarthy and Opitz (1985) and the other a new pair born of first-cousin parents. Both pairs of sisters had sensorineural deafness, ovarian dysgenesis, short stature, and mild mental retardation. During their teen years, they all developed severe, progressive sensory and motor peripheral neuropathy. Fiumara et al. (2004) proposed that there are 2 forms of Perrault syndrome: an apparently nonprogressive form and another, exemplified by their patients and those described by McCarthy and Opitz (1985) and Nishi et al. (1988), with progressive axonal-cerebellar degeneration.
Marlin et al. (2008) reported 2 unrelated females and 2 sisters with sensorineural hearing impairment and ovarian dysgenesis; 1 of the sporadic cases also had mental retardation and neurologic abnormalities, with cerebellar ataxia, nystagmus, ophthalmoplegia, bilateral ptosis, and neuropathy. The authors reviewed the 34 cases from 15 families reported to date, noting that a hearing defect was present in 33 cases and that ovarian dysgenesis was reported in all female cases. Of 29 cases with a detailed clinical description, 11 (9 females and 2 males) had no neurologic abnormalities reported. Because all familial cases have involved sibs and 4 of the 15 families reported were consanguineous, Marlin et al. (2008) stated that transmission was probably autosomal recessive.
McMillan et al. (2012) reported 2 teenaged brothers of European descent with a neurodegenerative disorder. They both developed sensorineural hearing loss in early childhood, followed by onset of a sensorimotor peripheral neuropathy. The older brother was more severely impaired, developing ataxia, pes cavus, and hammertoes around age 11 years after normal motor development. Visual acuity was normal, but detailed studies suggested rod dysfunction and retinal atrophy, consistent with retinitis pigmentosa. Brain MRI showed prominent cerebellar atrophy. The disorder was progressive; at age 16.5 years, he required a wheelchair for long distances. Growth and puberty were normal. The younger brother had similar but milder features, except for mildly delayed puberty at age 14. Both patients had normal cognition. Laboratory studies in both patients showed normal very long-chain and branched fatty acids and normal bile acids, although there was some reduction of pristanic acid beta-oxidation in patient fibroblasts.
Lines et al. (2014) reported 3 Italian sibs, including 2 sisters, with Perrault syndrome. All presented with sensorineural hearing loss in mid-childhood, followed by ataxia and progressive cognitive decline from adolescence onward. Brain imaging showed severe cerebellar atrophy, and the patients showed dysarthria and nystagmus. Other features included a progressive peripheral neuropathy with hyporeflexia and diminished sensation, lower extremity spasticity and weakness, pes cavus, and some hyperkinesia. Electrophysiologic studies indicated a motor demyelinating polyneuropathy. One sister had primary amenorrhea and the other had secondary amenorrhea; both had increased FSH and LH and decreased estradiol. The brother had increased FSH and decreased testosterone. The brother had a more complicated phenotype with progressive infra- and supratentorial white matter lesions and oligoclonal bands in the CSF. He also had internuclear ophthalmoplegia and severe intellectual disability, and became wheelchair-bound in his early thirties. Additional laboratory studies of all patients showed increased serum total bile acids, but phytanic and very long-chain fatty acids were normal. Patient fibroblasts showed decreased beta-oxidation of pristanic acid. Peroxisome morphology was normal.
Genetic Heterogeneity
Pierce et al. (2010) found no mutations in the HSD17B4 gene in 6 families with hearing loss and ovarian dysgenesis, both with and without neurologic symptoms, thus demonstrating genetic heterogeneity of Perrault syndrome.
In 9 families with Perrault syndrome, Pierce et al. (2011) detected no mutations in the HSD17B or HARS2 genes, providing evidence for further genetic heterogeneity.
Jenkinson et al. (2012) excluded mutations in the HSD17B4 and HARS2 genes in 8 families with Perrault syndrome, providing further evidence for genetic heterogeneity. Their families included patients with hearing loss and ovarian dysgenesis only, as well as patients with additional variable neurologic defects, such as peripheral neuropathy, microcephaly, ataxia, and seizures.
The transmission pattern of Perrault syndrome in the family reported by Perrault et al. (1951) was consistent with autosomal recessive inheritance.
Pierce et al. (2010) performed whole-exome sequencing of genomic DNA from 1 of the sisters with Perrault syndrome previously described by McCarthy and Opitz (1985) and Fiumara et al. (2004) and identified 2 rare variants in the HSD17B4 gene (601860.0008 and 601860.0009). Sequencing revealed that both the proband and her affected sister were compound heterozygous for the missense and nonsense mutations, and that their unaffected mother was heterozygous for the missense mutation. Mutation in HSD17B4 had previously been found to cause an autosomal recessive disorder of peroxisomal fatty acid beta-oxidation that is generally fatal within the first 2 years of life (DBP deficiency; 261515). Pierce et al. (2010) stated that no females with DBP deficiency surviving past puberty had been reported, and ovarian dysgenesis had not previously been associated with that disorder. Pierce et al. (2010) concluded that Perrault syndrome and DBP deficiency overlap clinically, and that DBP deficiency may be underdiagnosed.
In 2 brothers of European descent with Perrault syndrome, McMillan et al. (2012) identified compound heterozygous mutations in the HSD17B4 gene (A34V, 601860.0010 and I516T, 601860.0011). Each mutation affected a different domain, dehydrogenase and hydratase, respectively. The mutations, which were found by exome sequencing and confirmed by Sanger sequencing, segregated with the disorder in the family. McMillan et al. (2012) postulated that the relatively mild phenotype was due to the fact that only 1 of the functional HSD17B4 domains was affected on each allele. There was reduced but detectable DBP hydratase and dehydrogenase activity, with some reduction of pristanic acid beta-oxidation in patient fibroblasts. The 45-kD DBP fragment was not detected by immunoblot analysis; however, peroxisomes and plasma very long-chain and branched fatty acids were normal. McMillan et al. (2012) suggested the designation DBP deficiency type IV to refer to mutations affecting 2 different enzyme domains but associated with a relatively mild phenotype.
In 3 Italian sibs with Perrault syndrome, Lines et al. (2014) identified compound heterozygous missense mutations in the HSD17B4 gene (P513L, 601860.0012 and R543P, 601860.0013), both affecting the hydratase domain. The mutations were found by whole-exome sequencing and were shown by immunoblot analysis to result in a significant decrease in hydratase activity as well as in absence of the 45-kD posttranslational fragment containing the hydratase domain.
