    Description: Autism spectrum disorders comprise a range of neurodevelopmental disorders characterized by deficits in social interaction and communication, and by repetitive behaviour. Mutations in synaptic proteins such as neuroligins, neurexins, GKAPs/SAPAPs and ProSAPs/Shanks were identified in patients with autism spectrum disorder, but the causative mechanisms remain largely unknown. ProSAPs/Shanks build large homo- and heteromeric protein complexes at excitatory synapses and organize the complex protein machinery of the postsynaptic density in a laminar fashion. Here we demonstrate that genetic deletion of ProSAP1/Shank2 results in an early, brain-region-specific upregulation of ionotropic glutamate receptors at the synapse and increased levels of ProSAP2/Shank3. Moreover, ProSAP1/Shank2(-/-) mutants exhibit fewer dendritic spines and show reduced basal synaptic transmission, a reduced frequency of miniature excitatory postsynaptic currents and enhanced N-methyl-d-aspartate receptor-mediated excitatory currents at the physiological level. Mutants are extremely hyperactive and display profound autistic-like behavioural alterations including repetitive grooming as well as abnormalities in vocal and social behaviours. By comparing the data on ProSAP1/Shank2(-/-) mutants with ProSAP2/Shank3alphabeta(-/-) mice, we show that different abnormalities in synaptic glutamate receptor expression can cause alterations in social interactions and communication. Accordingly, we propose that appropriate therapies for autism spectrum disorders are to be carefully matched to the underlying synaptopathic phenotype.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schmeisser, Michael J -- Ey, Elodie -- Wegener, Stephanie -- Bockmann, Juergen -- Stempel, A Vanessa -- Kuebler, Angelika -- Janssen, Anna-Lena -- Udvardi, Patrick T -- Shiban, Ehab -- Spilker, Christina -- Balschun, Detlef -- Skryabin, Boris V -- Dieck, Susanne tom -- Smalla, Karl-Heinz -- Montag, Dirk -- Leblond, Claire S -- Faure, Philippe -- Torquet, Nicolas -- Le Sourd, Anne-Marie -- Toro, Roberto -- Grabrucker, Andreas M -- Shoichet, Sarah A -- Schmitz, Dietmar -- Kreutz, Michael R -- Bourgeron, Thomas -- Gundelfinger, Eckart D -- Boeckers, Tobias M -- England -- Nature. 2012 Apr 29;486(7402):256-60. doi: 10.1038/nature11015.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute for Anatomy and Cell Biology, Ulm University, 89081 Ulm, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22699619" target="_blank"〉PubMed〈/a〉

    Description: The highly complex structure of the human brain is strongly shaped by genetic influences. Subcortical brain regions form circuits with cortical areas to coordinate movement, learning, memory and motivation, and altered circuits can lead to abnormal behaviour and disease. To investigate how common genetic variants affect the structure of these brain regions, here we conduct genome-wide association studies of the volumes of seven subcortical regions and the intracranial volume derived from magnetic resonance images of 30,717 individuals from 50 cohorts. We identify five novel genetic variants influencing the volumes of the putamen and caudate nucleus. We also find stronger evidence for three loci with previously established influences on hippocampal volume and intracranial volume. These variants show specific volumetric effects on brain structures rather than global effects across structures. The strongest effects were found for the putamen, where a novel intergenic locus with replicable influence on volume (rs945270; P = 1.08 x 10(-33); 0.52% variance explained) showed evidence of altering the expression of the KTN1 gene in both brain and blood tissue. Variants influencing putamen volume clustered near developmental genes that regulate apoptosis, axon guidance and vesicle transport. Identification of these genetic variants provides insight into the causes of variability in human brain development, and may help to determine mechanisms of neuropsychiatric dysfunction.〈br /〉〈br /〉〈a

    Abstract: Autism spectrum disorders (ASD) are a heterogeneous group of neurodevelopmental disorders with a complex inheritance pattern. While many rare variants in synaptic proteins have been identified in patients with ASD, little is known about their effects at the synapse and their interactions with other genetic variations. Here, following the discovery of two de novo SHANK2 deletions by the Autism Genome Project, we identified a novel 421 kb de novo SHANK2 deletion in a patient with autism. We then sequenced SHANK2 in 455 patients with ASD and 431 controls and integrated these results with those reported by Berkel et al. 2010 (n = 396 patients and n = 659 controls). We observed a significant enrichment of variants affecting conserved amino acids in 29 of 851 (3.4%) patients and in 16 of 1,090 (1.5%) controls (P = 0.004, OR = 2.37, 95% CI = 1.23-4.70). In neuronal cell cultures, the variants identified in patients were associated with a reduced synaptic density at dendrites compared to the variants only detected in controls (P = 0.0013). Interestingly, the three patients with de novo SHANK2 deletions also carried inherited CNVs at 15q11-q13 previously associated with neuropsychiatric disorders. In two cases, the nicotinic receptor CHRNA7 was duplicated and in one case the synaptic translation repressor CYFIP1 was deleted. These results strengthen the role of synaptic gene dysfunction in ASD but also highlight the presence of putative modifier genes, which is in keeping with the "multiple hit model" for ASD. A better knowledge of these genetic interactions will be necessary to understand the complex inheritance pattern of ASD.

    Notes: Abstract Zinc content of serum, hair and erythrocytes, urinary zinc excretion, zinc clearance (CZn) and the ratio of CZn to creatinine clearance (CCr) (CZn/CCr) were measured in 32 children aged between 2.1 and 14.4 years suffering from idiopathic nephrotic syndrome (INS) without renal failure (CCr〉70 ml/min 1.73 m2 body surface area). Nineteen subjects had proteinuria and the remaining 13 were in remission. All children received calcium and vitamin D supplementation while on steroid therapy. There was high dietary zinc and protein intake. The results were compared with those obtained from 19 healthy subjects (aged 2–14 years). Zinc concentration in serum, erythrocytes and urine were measured by a colourimetric method. Proton induced X-ray emission was used to determine zinc content in hair. In patients both with and without proteinuria, the mean contents of serum, hair and erythrocytes were significantly lower than in the control group. The urinary zinc excretion, CZn and CZn/CCr in INS children were significantly higher than in the control group. A positive correlation was found between urinary zinc and protein excretion. In spite of high dietary zinc intake and normal intestinal absorption, children with INS had a zinc deficiency. This was probably caused by an increased urinary zinc loss.

    Notes: Abstract  Cyclic voiding cystourethrography (CVC) enhances the detection of vesicoureteric reflux (VUR). We investigated whether more-severe VUR may be overlooked, and whether older children are at risk of having their VUR missed with the conventional single-cycle study. Three hundred and seventy patients, 168 boys and 202 girls aged 1 month to 16 years, consecutively admitted over 1 year for suspicion of VUR, underwent two complete cycles of filling and voiding CVC. One hundred and four subjects, 33 boys and 71 girls, were older than 3 years (mean age 5.7 years, range 3.2–16 years).Sixty-six refluxing ureters from 51 patients were identified in the first cycle and 61 refluxing ureters from 45 patients were identified only with the second cycle. Four instances of grade IV VUR in 4 patients and three of grade V VUR in 3 patients were overlooked completely in the first cycle. Seven episodes of VUR ≤ grade III from 5 patients diagnosed in the first cycle were upgraded to ≥ grade IV at the second cycle. The presence of VUR was identified only in the second cycle in 35 of 74 subjects aged ≤ 3 years and in 10 of 22 aged 〉3 years (not significant). Of the 10 children aged 〉3 years, 2, who had diagnosis only at the second cycle, had ≥ grade IV VUR. More-severe VUR may be overlooked or down-graded in a single-cycle study. Two-cycle CVC is also useful in children older than 3 years.

    Notes: Abstract  Idiopathic hypercalciuria (IHC) has been reported mainly in children with hematuria in the 1980s and early 1990s, when renal sonography was just becoming routine. The presence of microcalculi, i.e., of hyperechogenic spots 〈3 mm in diameter in renal calyces, was not taken into account in those studies. We attempted to outline clinical presentation and natural course of IHC not only in children with hematuria, but also in those with dysuria and/or recurrent abdominal/flank pain and a family history of nephrolithiasis, taking into account the finding of microcalculi. We analyzed retrospectively the data at diagnosis from 74 consecutive children aged 2.4–18 years (mean 8.6) with IHC (calciuria 4.1–15.1 mg kg–1 24 h–1, mean 6.1) and the outcome of 30 of them who were followed ≥1 years (mean 3.2) with no specific therapy. At diagnosis, 38 patients (51%) had no hematuria, 42 (57%) had microcalculi and four (5%) had calculi. Of the patients with normal urinalysis, 71% had microcalculi or stones. The subjects with microcalculi and those with stones were significantly older than those without microcalculi and stones (P=0.004 and 0.007). A normal urinalysis at our evaluation and a history of abdominal/flank pain were significantly more frequent in patients with microcalculi than in those without (P=0.02 and 0.0001, respectively). During the follow-up, four of 30 patients formed stones 1–3 years after first diagnosis of IHC. More than half of children with IHC have microcalculi. The risk of formation of microcalculi or stones increases with age. The lack of hematuria does not exclude the presence of microcalculi or calculi. Hypercalciuria has to be suspected in children with dysuria and/or recurrent abdominal/ flank pain and a family history of nephrolithiasis, even when they have no hematuria.

    Notes: Abstract  We studied the prevalence of a history of nephrolithiasis in first- and second-degree relatives of 74 children with hypercalciuria (HC), 61 with hyperuricosuria (HU), and 41 with HC plus HU, and in a control population of 261 children with different diseases. Family history of nephrolithiasis was found in 69% of HC, 75% of HU, 78% of HC plus HU, and 22% of control patients. The prevalence was not different among HC, HU, and HC plus HU groups, but was significantly higher in each study group than the control group (P=0.0001). Body mass index 〉95th percentile was found in only 4.7% of the patients with HC or HC plus HU. Calculi (〉3 mm in diameter) were present in 8.9% of the patients with a family history of nephrolithiasis and in 9.4% of those with no family history (P=0.85). Microcalculi (〈3 mm in diameter) were found by sonography in 56.6% of the patients with and in 53.3% of those without a family history of nephrolithiasis (P=0.83). Children with HC and/or HU have a strong familial prevalence of nephrolithiasis. Obesity does not seem to affect the association of familial nephrolithiasis and hypercalciuria in children. The presence of nephrolithiasis in families of children with HC and/or HU is not associated with a higher rate of formation of calculi or microcalculi.
