A metastatic ureteral tumor successfully treated with multidisciplinary therapy including radiotherapy.

Introduction: Metastatic ureteral tumors are difficult to diagnose pathologically. Treatment is only available for the primary disease, and prognosis is generally poor.

Case Presentation: A 63-year-old patient with a history of gastric cancer presented with asymptomatic right-sided hydronephrosis.

Additional findings of tibial dysplasia in a male with orofaciodigital syndrome type XVI.

We describe the case of a male patient with orofaciodigital (OFD) syndrome type XVI with a homozygous variant of TMEM107 (p.Phe106del) and the additional findings of tibial dysplasia, which is a pivotal finding of OFD syndrome type IV. His family history included two fetuses with anencephaly with or without cleft lip/palate and polydactyly with no genetic information.

A severe case of status dystonicus caused by a de novo KMT2B missense mutation.

Here, we present the case of a 15-year-old Japanese girl with Dystonia 28, childhood-onset; DYT28 (MIM#606834) showing early-onset generalized progressive dystonia and status dystonicus. The patient was genetically undiagnosed and had not responded to various medications. By trio-based whole exome sequencing and in silico analyses, we identified a de novo heterozygous variant of KMT2B: NM_014727.

A novel homozygous missense mutation in three CACT-deficient patients: clinical and autopsy data.

Carnitine-acylcarnitine translocase (CACT) deficiency is a fatty acid ß-oxidation disorder of the carnitine shuttle in mitochondria, with a high mortality rate in childhood. We evaluated three patients, including two siblings, with neonatal-onset CACT deficiency and revealed identical homozygous missense mutations of p.Arg275Gln within the gene.
