PMR4-dependent cell wall depositions are a consequence but not the cause of temperature-induced autoimmunity.

Plants possess a well-balanced immune system that is required for defense against pathogen infections. In autoimmune mutants or necrotic crosses, an intrinsic temperature-dependent imbalance leads to constitutive immune activation, resulting in severe damage or even death of plants. Recently, cell wall depositions were described as one of the symptoms following induction of the autoimmune phenotype in Arabidopsis saul1-1 mutants.

Novel CIC point mutations and an exon-spanning, homozygous deletion identified in oligodendroglial tumors by a comprehensive genomic approach including transcriptome sequencing.

Oligodendroglial tumors form a distinct subgroup of gliomas, characterized by a better response to treatment and prolonged overall survival. Most oligodendrogliomas and also some oligoastrocytomas are characterized by a unique and typical unbalanced translocation, der(1,19), resulting in a 1p/19q co-deletion. Candidate tumor suppressor genes targeted by these losses, CIC on 19q13.

Severe intellectual disability, West syndrome, Dandy-Walker malformation, and syndactyly in a patient with partial tetrasomy 17q25.3.

We report on a de novo 0.5 Mb triplication (partial tetrasomy) of chromosome 17q25.3 in a 10-year-old girl with severe intellectual disability, infantile seizures (West syndrome), moderate hearing loss, Dandy-Walker malformation, microcephaly, craniofacial dysmorphism, striking cutaneous syndactyly (hands 3-4, feet 2-3), joint laxity, and short stature.

Partial deletion of GLRB and GRIA2 in a patient with intellectual disability.

We report about the partial de novo loss of GLRB and GRIA2 in an individual with intellectual disability (ID). No additional mutations were found in either gene. GLRB itself does not seem to be a good candidate as it causes autosomal recessive hyperekplexia and no symptoms were found in the patient.

1.6Mb deletion in chromosome band 3q29 associated with eye abnormalities.

We report on a patient with a de novo microdeletion 3q29 detected by molecular karyotyping using array CGH analysis. The girl displayed microphthalmia and cataract, hyperplastic pyloric stenosis, mild dysmorphic facial features, and developmental delay. Array CGH analysis uncovered a 1.

Small reciprocal insertion detected by spectral karyotyping (SKY) and delimited by array-CGH analysis.

A 5.4-year-old male propositus is reported with mild dysmorphic features including hypoplasia of the radial part of both hands affecting thenar, thumb and fingers 2-3, incomplete syndactyly of fingers 3-4, single palmar creases, brachymesophalangia of toes 3-5, dissociated retardation of bone age, telecanthus, spina bifida occulta, cryptorchidism, muscular hypotonia, and borderline mental retardation. His karyotype was unbalanced, 46,XY,der(16)ins(4;16)(q26q28.

Neuromuscular contacts induce nitric oxide signals in skeletal myotubes in vitro.

It has previously been shown that skeletal myotubes express nitric oxide synthase (NOS) and produce and release NO signals. NOS is also part of agrin-induced acetylcholine receptor aggregations on myotubes. As nerve-muscle interactions underlie reciprocal signaling mechanisms, we hypothesized that NO signals in target myotubes may be induced by neuromuscular contacts in development.
