Perrault syndrome 6
A form of Perrault syndrome, a sex-influenced disorder characterized by sensorineural deafness in both males and females, and ovarian dysgenesis in females. Affected females have primary amenorrhea, streak gonads, and infertility, whereas affected males show normal pubertal development and are fertile. PRLTS6 inheritance is autosomal recessive.
Catalytic ribonuclease component of mitochondrial ribonuclease P, a complex composed of TRMT10C/MRPP1, HSD17B10/MRPP2 and PRORP/MRPP3, which cleaves tRNA molecules in their 5'-ends (PubMed:18984158, PubMed:25953853, PubMed:34715011). The presence of TRMT10C/MRPP1, HSD17B10/MRPP2 is required to catalyze tRNA molecules in their 5'-ends (PubMed:25953853)
Mitochondrion
Combined oxidative phosphorylation deficiency 54
An autosomal recessive, multisystem disorder with highly variable manifestations resulting from defective mitochondrial transcription and translation. Clinical features include early-onset sensorineural hearing loss, sometimes associated with global developmental delay or primary ovarian failure, peripheral hypertonia, seizures, muscle weakness, behavioral abnormalities, and leukoencephalopathy on brain imaging. Serum lactate may or may not be elevated.
Catalyzes the trans-addition of the three molecules of IPP onto DMAPP to form geranylgeranyl pyrophosphate, an important precursor of carotenoids and geranylated proteins

Muscular dystrophy, congenital hearing loss, and ovarian insufficiency syndrome
An autosomal recessive disorder characterized by early-onset progressive muscle weakness, sensorineural hearing loss, and primary amenorrhea due to ovarian insufficiency. Some patients become wheelchair-bound by the second decade, whereas others have a milder phenotype and maintain independent ambulation into adulthood. Most patients have respiratory insufficiency.
Required for mitochondrial translation, possibly by coordinating the assembly or maintenance of the mitochondrial ribosome (PubMed:23022098, PubMed:25604853)
Mitochondrion
Combined oxidative phosphorylation deficiency 11
A severe, multisystemic, autosomal recessive, disorder characterized by deficiencies of multiple mitochondrial respiratory enzymes leading to neonatal hypotonia and lactic acidosis. Affected individuals may have respiratory insufficiency, foot deformities, or seizures.
Protease component of the ClpXP complex that cleaves peptides and various proteins in an ATP-dependent process. Has low peptidase activity in the absence of CLPX. The ClpXP complex can degrade CSN1S1, CSN2 and CSN3, as well as synthetic peptides (in vitro) and may be responsible for a fairly general and central housekeeping function rather than for the degradation of specific substrates (PubMed:11923310, PubMed:15522782). Cleaves PINK1 in the mitochondrion (PubMed:22354088)

Progressive external ophthalmoplegia with mitochondrial DNA deletions, autosomal dominant, 3
A disorder characterized by progressive weakness of ocular muscles and levator muscle of the upper eyelid. In a minority of cases, it is associated with skeletal myopathy, which predominantly involves axial or proximal muscles and which causes abnormal fatigability and even permanent muscle weakness. Ragged-red fibers and atrophy are found on muscle biopsy. A large proportion of chronic ophthalmoplegias are associated with other symptoms, leading to a multisystemic pattern of this disease. Additional symptoms are variable, and may include cataracts, hearing loss, sensory axonal neuropathy, ataxia, depression, hypogonadism, and parkinsonism.
Bifunctional enzyme acting on the peroxisomal fatty acid beta-oxidation pathway. Catalyzes two of the four reactions in fatty acid degradation: hydration of 2-enoyl-CoA (trans-2-enoyl-CoA) to produce (3R)-3-hydroxyacyl-CoA, and dehydrogenation of (3R)-3-hydroxyacyl-CoA to produce 3-ketoacyl-CoA (3-oxoacyl-CoA), which is further metabolized by SCPx. Can use straight-chain and branched-chain fatty acids, as well as bile acid intermediates as substrates

The human induced pluripotent stem cell line CTGUi-002A was generated from a Perrault syndrome patient.
We generated an induced pluripotent stem cell (iPSC) line, designated CTGUi002-A, from peripheral blood mononuclear cells (PBMCs) of a 9-year-old female with Perrault syndrome carrying biallelic TWNK mutations (c.811G>A and c.1163C>T), using Sendai virus-mediated delivery of OCT4, SOX2, KLF4, and c-MYC. The CTGUi002-A iPSC line retained the TWNK mutations and exhibited characteristic iPSC morphology, expressed pluripotency markers, maintained a normal karyotype, and demonstrated trilineage differentiation potential.
Novel LARS2 variants in patients with Perrault syndrome: expanding the genetic spectrum and phenotypic heterogeneity.
Perrault syndrome (PS) is a rare autosomal recessive disorder characterized by sensorineural hearing loss (SNHL) and primary ovarian insufficiency in females. LARS2, encoding mitochondrial leucyl-tRNA synthetase, is the most common causative gene for PS. However, the genetic spectrum and clinical variability of PS remain underexplored. Expanding the catalog of LARS2 variants and correlating them with phenotypic data are critical for delineating genotype-phenotype relationships. Two unrelated Chinese probands with hearing loss were enrolled, and comprehensive clinical evaluations were performed. Whole-exome sequencing (WES) was used to identify genetic variants, followed by Sanger sequencing for family co-segregation verification. Minigene assays and RT-PCR were conducted to assess the splicing effect of the novel canonical splice-site variant LARS2 c.235-2A>G. For the novel missense variant LARS2 c.1661T>C, 3-D structural modeling and evolutionary conservation analysis were performed to evaluate its pathogenicity. Moreover, we comprehensively summarized all LARS2 variants associated with PS via an extensive literature review. Proband 1 (12-year-old female) harbors compound heterozygous variants LARS2 c.235-2A>G (novel) and LARS2 c.880G>A, presenting with profound SNHL, primary ovarian insufficiency, and developmental delay. Proband 2 (7-year-old male) carries compound heterozygous variants LARS2 c.1661T>C (novel) and LARS2 c.1886C>T, manifesting severe SNHL with an unusual upsloping audiogram pattern and comprehension difficulties. Functional assays confirmed that LARS2 c.235-2A>G disrupts canonical splicing, leading to exon 4 skipping and in-frame deletions. 3-D structural modeling and conservation analysis revealed that LARS2 c.1661T>C likely impairs protein stability by altering residue interactions, with Val554 being highly conserved across species. According to the ACMG/AMP guideline, both novel LARS2 variants were classified as likely pathogenic. We identified two novel LARS2 variants associated with PS in Chinese patients, thereby expanding the LARS2 genetic spectrum and providing precise molecular evidence for clinical management and genetic counseling. This study enhances understanding of genotype-phenotype correlations in PS, thereby revealing the phenotypic heterogeneity of LARS2 variants.
Expanding the genotypic spectrum of combined oxidative phosphorylation deficiency 54.
Biallelic hypomorphic variants in PRORP cause the rare autosomal recessive disorder combined oxidative phosphorylation deficiency type 54 (COXPD54). COXPD54 encompasses a clinical spectrum of sensorineural hearing loss and ovarian insufficiency (Perrault syndrome) to leukodystrophy with developmental delay and epilepsy. Here, we report two new affected individuals with biallelic PRORP variants with clinical features consistent with COXPD54. One individual was homozygous for c.1505G > A p.Arg502Gln, whereas the other was compound heterozygous for c.1510C > T, p.His504Tyr and c.893C > A, p.Ser298Ter (NM_014672.4). In vitro tRNA processing assays revealed decreased mitochondrial 5′ tRNA leader cleavage by human RNase P complex with the two novel missense PRORP metallonuclease domain variants. These data provide further evidence that biallelic PRORP variants disrupt 5’ tRNA leader cleavage and are associated with a pleiotropic phenotype of COXPD54. The online version contains supplementary material available at 10.1007/s10048-026-00892-5.
Patient-derived TWNK variants recapitulate multisystem Perrault syndrome pathology in a mouse model.
Perrault syndrome (PS) is a rare autosomal-recessive disorder characterized by bilateral sensorineural hearing loss, ovarian dysgenesis in females, and variable neurological impairment. Pathogenic variants in TWNK, encoding the mitochondrial helicase Twinkle, disrupt mtDNA maintenance and underlie a subset of PS cases. Here, we generated the first mouse models carrying patient-specific TWNK missense mutations c.814G > A (p.Ala272Thr) and c.1166C > T (p.Ala389Val), both in homozygosity and compound heterozygosity, using CRISPR/Cas9 editing. Mutant mice exhibit profound hearing loss, locomotor hypoactivity, and axonal peripheral neuropathy, while overall growth remains normal. Molecular assays reveal a significant reduction in mtDNA copy number and ATP content in muscle and brain, accompanied by impaired respiratory-chain function. These phenotypes faithfully recapitulate core features of human PS, establishing a genetically precise in vivo platform to dissect disease mechanisms and to evaluate targeted therapies for mitochondrial dysfunction and sensorineural hearing loss.
A novel CLPP variant in a Pakistani family with Perrault syndrome associated with recurrent fevers.
Perrault syndrome (PRLTS) is an autosomal recessive disease with sensorineural hearing loss and ovarian dysfunction in girls, and either a fluctuating neurological phenotype or not. PRLTS type 2 is known to be caused by pathogenic variants of the CLPP gene that encodes mitochondrial ATP-dependent protease. This paper involved clinical and genetic studies on a Pakistani family with PRLTS. Whole-exome sequencing identified a novel homozygous CLPP missense mutation (NM_006012.4: c.250 A > C; p.Ile84Leu). Its pathogenicity was assessed with the help of multiple sequence alignment, AlphaFold protein modeling, and docking with CLPX with the help of ClusPro. Auditory brainstem responses and tympanometry were in clinical assessment. The individuals were found to have a uniform phenotype of severe sensorineural hearing loss, mild intellectual disability, ataxia and frequent fever. There was one patient in whom the unilateral Eustachian tube dysfunction was hinted at by Tympanometry. At the molecular level, the identified CLPP variant involved a highly conserved residue. Structural modeling showed preserved protein architecture, whereas docking simulations revealed disrupted CLPP-CLPX interaction, suggesting a basis for impaired proteostasis. We report a novel CLPP missense variant (p.I84L) in a Pakistani family with PRLTS, expanding the mutational spectrum of CLPP. To the best of our knowledge, recurrent fever was reported in PRLTS for the first time, which expanded the PRLTS phenotype spectrum.
