INTRODUCTION:RNA polymerase III (Pol III)-related leukodystrophies are a group of autosomal recessive neurodegenerative disorders caused by mutations in POLR3A and POLR3B. Recently a recessive mutation in POLR1C causative of Pol III-related leukodystrophies was identified. METHODS:We report the case of a Tunisian girl of 14 years of age who was referred to ...

OBJECTIVE:SLC13A3 encodes the plasma membrane Na+ /dicarboxylate cotransporter 3, which imports inside the cell 4 to 6 carbon dicarboxylates as well as N-acetylaspartate (NAA). SLC13A3 is mainly expressed in kidney, in astrocytes, and in the choroid plexus. We describe two unrelated patients presenting with acute, reversible (and recurrent in one) ... Read more >>

Cystic leukoencephalopathy without megalencephaly is a disorder related in some cases to RNASET2 mutations and characterized by bilateral anterior temporal subcortical cysts and multifocal lobar white matter lesions with sparing of central white matter structures. This phenotype significantly overlaps with the sequelae of in utero cytomegalovirus (CMV) infection, including the ... Read more >>

Hypomyelination with atrophy of the basal ganglia and cerebellum (H-ABC) was first described in 2002. After the recent identification of TUBB4A mutation as the genetic basis of the disease, the clinical and neuroimaging phenotype related to TUBB4A mutations expanded, ranging from primary dystonia type 4 with normal MRI to severe ...

Insertion of an extra copy of Xq22.2 into 1p36 results in functional duplication of the PLP1 gene in a girl with classical Pelizaeus-Merzbacher disease.

BACKGROUND: Pelizaeus-Merzbacher disease (PMD) is an X-linked dysmyelinating disorder characterized by nystagmus, hypotonia, ataxia, progressive spasticity, and cognitive decline. PMD classically results from a duplication of a genomic segment encompassing the entire PLP1 gene. Since the PLP1 gene is located in Xq22, PMD affects mostly boys. METHODS AND RESULTS: Here ...

Hereditary spastic paraplegia is a neurodegenerative phenotype characterized by a progressive loss of corticospinal motor tract function. In a majority of affected individuals the pathogenesis remains undetermined.We identified a series of patients with a phenotype of nonsyndromic spastic paraplegia in whom no diagnosis had been reached before exome sequencing. We ... Read more >>

Involvement of interstitial telomeric sequences in two new cases of mosaicism for autosomal structural rearrangements.

Jonathan Lévy, Aline Receveur, Guillaume Jedraszak, Sandra Chantot-Bastaraud, Florence Renaldo, Jean Gondry, Joris Andrieux, Henri Copin, Jean-Pierre Siffroi, Marie-France Portnoï,

Mosaicism for an autosomal structural rearrangement that does not involve ring or marker chromosomes is rare. The mechanisms responsible for genome instability have not always been explained. Several studies have shown that interstitial telomeric sequences (ITSs), involved in some mosaic constitutional anomalies, are potent sources of genomic instability. Here we ... Read more >>
