The hypomyelinating leukodystrophies X-linked Pelizaeus-Merzbacher disease (PMD) and Pelizaeus-Merzbacher-like disease (PMLD) are characterized by nystagmus, progressive spasticity, and ataxia. In a consanguineous family with PMLD, we performed a genomewide linkage scan using the GeneChip Mapping EA 10K Array (Affymetrix) and detected a single gene locus on chromosome 1q41-q42. This region harb...

Recessive mutations in GJA12/Cx47, the gene encoding the gap junction protein connexin47 (Cx47), cause Pelizaeus-Merzbacher-like disease (PMLD), which is characterized by severe CNS dysmyelination. Three missense PMLD mutations, P87S, Y269D and M283T, were expressed in communication-incompetent HeLa cells, and in each case the mutant proteins appeared to at least partially accumulate in the ER....

pelizaeus­-merzbacher-like disease (pmld) is a hypomyelinating leukoencephalopathy disorder with a genetically heterogeneous pattern. mutations in the gja12/gjc2 gene cause one form of autosomal recessive pelizaeus­-merzbacher-like disease. here, we report a new mutation in a ­10-month-old girl with nystagmus, psychomotor delay, hypotonicity, head nodding and dysmyelination from healthy second ...

OBJECTIVES To study potentially traumatic events (PTE), post-traumatic stress disorder (PTSD), anxiety, depression, somatization and post-migration living difficulties (PMLD) in primary care immigrants. DESIGN Patients self-rated transculturally validated questionnaires. Those with and without PTSD were compared on all variables. The influence of the number of PTE and of PMLD on PTSD was meas...

The role of post-migration living difficulties (PMLD) on somatization was studied in 101 first generation immigrants visited in primary care. Premigratory traumas and post-traumatic stress disorder (PTSD) were also assessed. About one third of patients somatized. Sociodemographic variables were similar in somatizers and non-somatizers. Premigratory traumas, PTSD and the likelihood to report at ...

Gap junctions (GJ) allow direct intercellular communication, and consist of connexins (Cx). In the mammalian central nervous system, oligodendrocytes express Cx29, Cx32 and Cx47, whereas astrocytes express Cx26, Cx30 and Cx43. Cx47/Cx47 GJs couple oligodendrocytes, and Cx47/Cx43 channels are the primary heterotypic GJs at oligodendrocyte/astrocyte junctions. Interestingly, mutations in Cx47 hav...

Pelizaeus--Merzbacher-like disease (PMLD) is a hypomyelinating leukoencephalopathy disorder with a genetically heterogeneous pattern. Mutations in the GJA12/GJC2 gene cause one form of autosomal recessive Pelizaeus--Merzbacher-like disease. Here, we report a new mutation in a -10-month-old girl with nystagmus, psychomotor delay, hypotonicity, head nodding and dysmyelination from healthy second ...

BACKGROUND Profound and multiple learning disabilities (PMLD) are a complex range of disabilities that affect the general health and well-being of the individual and their capacity to interact and learn. METHOD We developed a new methodology to capture the non-symbolic signalling behaviours of children with PMLD within the context of a face-to-face interaction with a caregiver to provide anal...

Recessive mutations in GJA12/GJC2, the gene that encodes the gap junction protein connexin47 (Cx47), cause Pelizaeus-Merzbacher-like disease (PMLD), an early onset dysmyelinating disorder of the CNS, characterized by nystagmus, psychomotor delay, progressive spasticity and cerebellar signs. Here we describe three patients from one family with a novel recessively inherited mutation, 99C>G (predi...
