TP53RKEKC/KEOPS complex subunit TP53RKDisease-causing germline mutation(s) inTolerante
FUNÇÃO

Component of the EKC/KEOPS complex that is required for the formation of a threonylcarbamoyl group on adenosine at position 37 (t(6)A37) in tRNAs that read codons beginning with adenine (PubMed:22912744, PubMed:27903914). The complex is probably involved in the transfer of the threonylcarbamoyl moiety of threonylcarbamoyl-AMP (TC-AMP) to the N6 group of A37 (PubMed:22912744, PubMed:27903914). TP53RK has ATPase activity in the context of the EKC/KEOPS complex and likely plays a supporting role to

Galloway-Mowat syndrome 4

A form of Galloway-Mowat syndrome, a severe renal-neurological disease characterized by early-onset nephrotic syndrome associated with microcephaly, central nervous system abnormalities, developmental delays, and a propensity for seizures. Brain anomalies include gyration defects ranging from lissencephaly to pachygyria and polymicrogyria, and cerebellar hypoplasia. Most patients show facial dysmorphism characterized by a small, narrow forehead, large/floppy ears, deep-set eyes, hypertelorism and micrognathia. Additional variable features are visual impairment and arachnodactyly. Most patients die in early childhood.

OSGEP-Associated Galloway-Mowat Syndrome: A Longitudinal Genotype-Phenotype Correlation from Prenatal Imaging Markers to Lifespan Neurologic-Renal Trajectories.

QJM : monthly journal of the Association of Physicians2026 Mar 07

Galloway-Mowat syndrome type 3 (GAMOS3) is a rare autosomal recessive disorder characterized by the co-occurrence of renal and neurological abnormalities in early childhood, caused by OSGEP gene variants. This study aims to characterize the genetic and phenotypic spectrum of GAMOS3 and evaluate correlations from prenatal imaging features to lifelong neurological and renal manifestations. We retrospectively reviewed the medical records of cases genetically diagnosed with OSGEP-associated GAMOS3 at our center between January 2016 and August 2024. Additionally, a systematic review of reported cases in literature was conducted. The clinical validity of the gene-disease relationship between OSGEP and GAMOS3 was also evaluated in accordance with the ClinGen Gene-Disease Clinical Validity Curation Framework. The postnatal renal and neurological dysfunction was associated with prenatal manifestations, indicating disease progression. Prominent prenatal features included fetal growth restriction (FGR), microcephaly, oligohydramnios, and abnormal cranial imaging. Notably, FGR worsened with advancing gestation, predominantly affecting fetal head and abdominal growth while sparing long bones. Fetal central nervous system magnetic resonance imaging revealed uncommon findings such as abnormal sulcation and increased T2 signal in the white matter, suggestive of myelination defects or leukoencephalopathy. Trio-based medical exome sequencing identified novel variants in the OSGEP gene within this cohort, expanding the known genetic spectrum of GAMOS3. Furthermore, the gene-disease relationship between OSGEP and GAMOS3 was conclusively validated as "Definitive" according to clinical-genetic criteria. This study provides a comprehensive overview of the clinical phenotypes and genetic spectrum of GAMOS3, spanning from the prenatal period throughout the life course.

A novel homozygous frameshift mutation in the WDR73 gene causes Galloway-Mowat syndrome in a Chinese consanguineous family.

Ophthalmic genetics2026 Mar 04

Galloway-Mowat syndrome (GAMOS, OMIM: 251300) is a rare autosomal recessive (AR) neurodevelopmental disease, characterized by the combination of early-onset nephrotic syndrome and various central nervous system anomalies. The WD repeat-containing protein 73 (WDR73, OMIM: 616144) gene was the first gene found to be implicated in GAMOS1. An AR family with parental consanguinity underwent comprehensive clinical and genetic analyses. In this study, the variant identified by whole exome sequencing was confirmed by Sanger sequencing and cosegregation analysis. A literature review was conducted to summarize previously reported cases of GAMOS1 caused by mutations in the WDR73 gene. The proband with GAMOS1 was a 3-year-old boy with normal renal function and typical characteristics of GAMOS1, including idiopathic nystagmus, agenesis of genitalia, persistent axial hypotonia, mild cerebellar atrophy, thinning of the corpus callosum, and brainstem hypoplasia. A novel homozygous frameshift mutation c.972_973dupCT (p.F325Sfs * 10) in the exon 8 of the WDR73 gene was identified in the proband. We summarized thirty-six previously reported GAMOS1 cases caused by mutations in the WDR73 gene. We identified a novel homozygous frameshift mutation (c.972_973dupCT) in the WDR73 gene, causing AR GAMOS1 in a Chinese consanguineous family. The results are essential for further confirming the pathogenicity of WDR73 gene mutations and expanding the manifestation spectrum of GAMOS1.

Bilateral Cochlear Implantation in a Child With Galloway-Mowat Syndrome: A Case Report.

The American journal of case reports2026 Feb 28

BACKGROUND This report describes the surgical management and early auditory outcomes of bilateral cochlear implantation in a child with Galloway-Mowat syndrome (GAMOS). To the best of our knowledge, this is the first reported case of such surgery. GAMOS is an exceedingly rare genetic disorder characterized by microcephaly, early onset of steroid-resistant nephrotic syndrome, and brain anomalies. It is inherited in an autosomal recessive pattern and has a genetically heterogeneous basis. CASE REPORT We report the case of a young boy diagnosed with GAMOS who had profound bilateral deafness, cerebellar hypoplasia, hypotonia, epilepsy, and visual impairment likely due to optic nerve dysgenesis. Due to the deafness, he underwent bilateral cochlear implantation in 2 stages (at ages 2 and 3 years). No significant difficulties were encountered: appropriate surgical access was achieved despite partial bony overgrowth of the round window area, and soft electrodes were used to adapt to the dysplastic cochlear anatomy. Ethics committee approval was obtained and written informed parental consent was provided. Preliminary results at 6 months after the second implant were satisfactory. As a result of the cochlear implantation, the boy was able to perceive sounds and began using them to communicate with those around him. CONCLUSIONS Cochlear implantation can be a safe and effective solution for treating deafness in patients with GAMOS, at least in the short term, even if there are congenital defects such as cochlear dysplasia. Good surgical access and the use of soft electrodes are important in minimizing the risk of damage and maximizing auditory outcomes.

Refining the Phenotypic and Genotypic Spectrum of WDR73-Related Galloway-Mowat Syndrome: A Case Series and Systematic Review.

Neurology. Genetics2025 Aug

The aim of this report was to describe the phenotypic and genotypic spectrum of WDR73-related Galloway-Mowat syndrome (GAMOS). This study comprises a case series conducted from January 2016 to October 2024, along with a systematic review of WDR73-related GAMOS. Analysis was performed on demographic data, clinical features, neuroimaging findings, neurodevelopmental outcomes, and WDR73 gene variants of eligible individuals. We studied 64 individuals, including 4 from this case series and 60 from previous literature. The median reported age at disease onset ranged from 2.5 to 6 months. The most prevalent neurologic feature was microcephaly (55/64; 85.9%), followed by cerebellar atrophy (29/34; 85.3%), ocular abnormalities (54/64; 84.4%), axial hypotonia (52/64; 81.3%), and movement disorders (40/64; 62.5%). Proteinuria (37/64; 57.8%) was the leading extraneurologic feature while hiatal hernia (2/64; 3.1%) was the least observed classic feature. All individuals exhibited psychomotor impairment. A total of 18 WDR73 variants were identified, including 4 novel variants from this case series: c.21G > A (p.Trp7Ter), c.76G > A (p.Ala26Thr), c.214A > G (p.Arg72Gly), and c.884-171_c.*591del. Homozygous WDR73 variants were predominant (61/64; 95.3%) while 3 individuals carried compound heterozygous WDR73 variants. WDR73-related GAMOS is an autosomal recessive, infantile-onset neurodevelopmental disorder with multisystem involvement. Recognizing its clinical manifestations prior to genetic testing may help mitigate reproductive risks and facilitate comprehensive, individualized health care.
