Autosomal dominantly inherited spinocerebellar ataxias (SCAs) are a heterogeneous group of neurodegenerative disorders primarily affecting the cerebellum. Genetically, 26 different loci have been identified so far, although the corresponding gene has not yet been determined for 10 of them. Recently, mutations in the ATPase family gene 3-like 2 gene were(More)
The mechanisms underlying the transformation from chronic Helicobacter pylori gastritis to gastric extranodal marginal zone lymphoma (MALT lymphoma) are poorly understood. This study aims to identify microRNAs that might be involved in the process of neoplastic transformation. We generated microRNA signatures by RT-PCR in 68 gastric biopsy samples(More)
BACKGROUND Double-hit lymphomas (DHL) with chromosomal rearrangements affecting the avian myelocytomatosis viral oncogene homolog (cMYC) and either the B-cell lymphoma-2 (BCL2) or -6 (BCL6) locus are uncommon neoplasms with an aggressive clinical course and dismal prognosis. Most cases exhibit a phenotype intermediate between diffuse large B-cell lymphoma(More)
JO N 2 77 1 C-to-T change resulted in reduced expression level of the gene. The puratrophin-1 protein was also shown to be aggregated in Purkinje cells of affected patients [8]. The 16q-linked ataxia seems to be a frequent cause of hereditary ataxia in Japan being responsible for 10–48% of all cases [9–11]. The PLEKHG4 gene (at that time called(More)
Autosomal dominant spinocerebellar ataxias (SCAs) are heterogeneous neurological disorders characterised by cerebellar dysfunction mostly due to Purkinje cell degeneration. Genetically, 30 different loci have been identified so far whereas the corresponding gene has not yet been determined for 12 of them. The chromosomal location for the spinocerebellar(More)
Double-hit lymphomas (DHL) with MYC and either BCL2 or BCL6 rearrangements are rare neoplasms with an aggressive clinical presentation and grim prognosis. Moreover, molecular characterization of DHL remains insufficient, and especially the role of TP53 pathway disruption is unknown. We employed a next-generation sequencing approach to investigate the(More)
CONTEXT Primary extranodal diffuse large B-cell lymphomas of the thyroid (ptDLBCL) constitute a rare entity, which until now was not fully explored. OBJECTIVE Due to recently published data genetically linking ptDLBCL to a subset of thyroid carcinoma, we assessed the occurrence of oncogenic mutations and copy number alterations. DESIGN A high-resolution(More)
Ataxia with oculomotor apraxia type 2 (AOA2), a neurodegenerative disorder with juvenile to adolescent onset is caused by mutations within the SENATAXIN gene ( SETX). We performed molecular analyses in six patients showing clinically an AOA2 phenotype and moderate to significant elevated serum alpha-fetoprotein levels. Sequencing the 24 coding exons and(More)
The spinocerebellar ataxias (SCAs) with autosomal dominant inheritance are a clinically and genetically heterogeneous group of neurodegenerative disorders. To date 27 different loci have been identified for these conditions. Recently, two deletions as well as one missense mutation in the beta-III spectrin gene (STBN2) were identified causing SCA5. To(More)
The autosomal recessively inherited ataxia with oculomotor apraxia 2 (AOA2) is a neurodegenerative disorder characterized by juvenile or adolescent age of onset, gait ataxia, cerebellar atrophy, axonal sensorimotor neuropathy, oculomotor apraxia, and elevated serum AFP levels. AOA2 is caused by mutations within the senataxin gene (SETX). The majority of(More)
