What are the signatures of aggressive periodontitis? | ['This pilot study examined gene expression signatures in pathological gingival tissues of subjects with chronic or aggressive periodontitis, and explored whether new subclasses of periodontitis can be identified based on gene expression profiles.

Which tool is used for the identification of recurrent variants in noncoding regions? | ['LARVA: an integrative framework for large-scale analysis of recurrent variants in noncoding annotations.', "In cancer research, background models for mutation rates have been extensively calibrated in coding regions, leading to the identification of many driver genes, recurrently mutated more than expected. Noncoding regions are also associated with disease; however, background models for them have not been investigated in as much detail. This is partially due to limited noncoding functional annotation. Also, great mutation heterogeneity and potential correlations between neighboring sites give rise to substantial overdispersion in mutation count, resulting in problematic background rate estimation. Here, we address these issues with a new computational framework called LARVA. It integrates variants with a comprehensive set of noncoding functional elements, modeling the mutation counts of the elements with a β-binomial distribution to handle overdispersion. LARVA, moreover, uses regional genomic features such as replication timing to better estimate local mutation rates and mutational hotspots. We demonstrate LARVA's effectiveness on 760 whole-genome tumor sequences, showing that it identifies well-known noncoding drivers, such as mutations in the TERT promoter. Furthermore, LARVA highlights several novel highly mutated regulatory sites that could potentially be noncoding drivers.

Can mutations in Calmodulin cause ventricular fibrillation? | ['We characterized a family presenting with a history of ventricular fibrillation (VF) and sudden death without ECG or echocardiographic abnormalities at rest. Two siblings died suddenly at the ages of 9 and 10 years, and another two were resuscitated from out-of-hospital cardiac arrest with documented VF at age 10 and 16, respectively. Exome sequencing identified a missense mutation affecting a highly conserved residue (p.Phe90Leu) in the CALM1 gene encoding calmodulin. This mutation was also carried by one of the sibs who died suddenly, for whom DNA was available. The mutation was present in the mother and in an sibling, both asymptomatic but displaying a marginally prolonged QT-interval during exercise. CONCLUSIONS: We identified a mutation in CALM1 underlying IVF manifesting in childhood and adolescence. The causality of the mutation is supported by previous studies demonstrating that Phe90 mediates the direct interaction of CaM with target peptides', "Here we show that calmodulin (CaM), a ubiquitous Ca2+-sensing protein, binds to the carboxy-terminal 'IQ' domain of the human cardiac Na channel (hH1) in a Ca2+-dependent manner. This binding interaction significantly enhances slow inactivation-a channel-gating process linked to life-threatening idiopathic ventricular arrhythmias. Mutations targeted to the IQ domain disrupted CaM binding and eliminated Ca2+/CaM-dependent slow inactivation, whereas the gating effects of Ca2+/CaM were restored by intracellular application of a peptide modelled after the IQ domain.

DCM hallmark is the combination of dystrophic and hypertrophic alterations of cardiomyocytes.

The content of the recognized protein markers of cardiomyocyte hypertrophy such as tubulin, desmin and slow skeletal myosin heavy chain isoform, MHCbeta, was significantly elevated in DCM compared to normal myocardium.', 'In contrast, overexpression of desmin filaments by itself is not detrimental to the heart. Although loss-of-function studies have been more limited, ablation of the desmin gene causes mitochondrial dysfunction and apoptosis, resulting in cardiomyopathy in mice. From function studies, abnormal desmin aggregation and disruption of the desmin networks resulting from expression of either mutant desmin or mutant CryAB have been shown to remodel the heart and compromise cardiac function, suggesting their synergistic roles in disease pathogenesis.', 'A missense mutation in the desmin gene (DES) causes DCM in a human family.', 'Mice deficient in desmin, the muscle-specific member of the intermediate filament gene family, display defects in all muscle types and particularly in the myocardium.

Is there any role of TBR1 in autism? | ['TBR1 regulates autism risk genes in the developing neocortex', 'Exome sequencing studies have identified multiple genes harboring de novo loss-of-function (LoF) variants in individuals with autism spectrum disorders (ASD), including TBR1, a master regulator of cortical development. We performed ChIP-seq for TBR1 during mouse cortical neurogenesis and show that TBR1-bound regions are enriched adjacent to ASD genes. ASD genes were also enriched among genes that are differentially expressed in Tbr1 knockouts, which together with the ChIP-seq data, suggests direct transcriptional regulation. Of the nine ASD genes examined, seven were misexpressed in the cortices of Tbr1 knockout mice, including six with increased expression in the deep cortical layers. ASD genes with adjacent cortical TBR1 ChIP-seq peaks also showed unusually low levels of LoF mutations in a reference human population and among Icelanders. We then leveraged TBR1 binding to identify an appealing subset of candidate ASD genes.

It is therefore possible that TBR1 controls the expression of other autism risk factors. The downstream genes of TBR1 have been identified using microarray and promoter analyses. In this study, we annotated individual genes downstream of TBR1 and investigated any associations with ASDs through extensive literature searches. Of 124 TBR1 target genes, 23 were reported to be associated with ASDs.', 'Among these 24 genes, four transcription factors Auts2, Nfia, Nr4a2, and Sox5 were found, suggesting that TBR1 controls a transcriptional cascade relevant to autism pathogenesis. A further five of the 24 genes (Cd44, Cdh8, Cntn6, Gpc6, and Ntng1) encode membrane proteins that regulate cell adhesion and axonal outgrowth. These genes likely contribute to the role of TBR1 in regulation of neuronal migration and axonal extension. Besides, decreases in Grin2b expression and increases in Gad1 expression imply that neuronal activity may be aberrant in Tbr1 deficient mice.
