Galloway-Mowat syndrome.
Galloway-Mowat syndrome is a rare multisystem genetic disorder with constellation of neurological, skeletal, growth, facial, gastrointestinal and renal abnormalities. This case report describes Galloway-Mowat syndrome in a young boy suffering from congenital microcephaly, developmental delay, seizures and various dysmorphic features in whom nephrotic syndrome became apparent at 5 years of age.
متن کاملCollapsing Glomerulopathy in a Child with Galloway-Mowat Syndrome
Galloway-Mowat syndrome (GMS) is an autosomal recessive disorder with a poor prognosis that was first defined as a triad of central nervous system involvement, hiatal hernia, and nephrotic syndrome. However, this syndrome is now known to have a heterogeneous clinical presentation. The nephrotic syndrome is steroid resistant and is responsible for the outcome. The combination of collapsing glome...
متن کاملPeptides from aminoacyl-tRNA synthetases can cure the defects due to mutations in mt tRNA genes
Recent results from several laboratories have confirmed that human and yeast leucyl- and valyl-tRNA synthetases can rescue the respiratory defects due to mutations in mitochondrial tRNA genes. In this report we show that this effect cannot be ascribed to the catalytic activity per se and that isolated domains of aminoacyl-tRNA synthetases and even short peptides thereof have suppressing effects.
متن کاملRecessive nephrocerebellar syndrome on the Galloway-Mowat syndrome spectrum is caused by homozygous protein-truncating mutations of WDR73
We describe a novel nephrocerebellar syndrome on the Galloway-Mowat syndrome spectrum among 30 children (ages 1.0 to 28 years) from diverse Amish demes. Children with nephrocerebellar syndrome had progressive microcephaly, visual impairment, stagnant psychomotor development, abnormal extrapyramidal movements and nephrosis. Fourteen died between ages 2.7 and 28 years, typically from renal failur...
متن کاملInfant Boy with Microcephaly Gastroesophageal Reflux and Nephrotic Syndrome (Galloway-Mowat Syndrome): A Case Report
In this case report, we present the first diagnosed case of Galloway-Mowat syndrome in Iran. A 7 month old infant boy withmicrocephaly that had prominently stunted head growth afterbirth, gastroesophageal reflux, multiple craniofascial characters,hypothyroidism and nephrotic syndrome diagnosed at 5 monthsof age associated with rapid decline in renal function and heavyproteinuria in 2 months .
