This article is published with open access Abstract Genetic investigations of people with impaired development of spoken language provide windows into key aspects of human biology. Over 15 years after FOXP2 was identified, most speech and language impairments remain unexplained at the molecular level. We sequenced whole genomes of nineteen unrelated individuals diagnosed with childhood apraxia of speech, a rare disorder enriched for causative mutations of large effect. Where DNA was available from unaffected parents, CHD3 SETD1A WDR5 fi 1234567890();,: we discovered de novo mutations, implicating genes, including , and . In other probands, we identi ed novel loss-of-function variants affecting KAT6A, SETBP1, ZFHX4, TNRC6B and MKL2, regulatory genes with links to neurodevelopment. Several of the new candidates interact with each other or with known speech-related genes. Moreover, they show significant clustering within a single co-expression module of genes highly expressed during early human brain development. This study highlights gene regulatory pathways in the developing brain that may contribute to acquisition of proficient speech. -

Nelson1,10,* Chromatin remodeling through histone acetyltransferase (HAT) and histone deactylase (HDAC) enzymes affects fundamental cellular processes including the cell-cycle, cell differentiation, metabolism, and apoptosis. Nonsense mutations in genes that are involved in his- tone acetylation and deacetylation result in multiple congenital anomalies with most individuals displaying significant developmental delay, microcephaly and dysmorphism. Here, we report a syndrome caused by de novo heterozygous nonsense mutations in KAT6A (a.k.a., MOZ, MYST3) identified by clinical exome sequencing (CES) in four independent families. The same de novo nonsense mutation (c.3385C>T [p.Arg1129*]) was observed in three individuals, and the fourth individual had a nearby de novo nonsense mutation (c.3070C>T [p.Arg1024*]). Neither of these variants was present in 1,815 in-house exomes or in public databases. -
Weighted Burden Analysis of Exome-Sequenced Case-Control Sample Implicates Synaptic Genes in Schizophrenia Aetiology
Behavior Genetics (2018) 48:198–208 https://doi.org/10.1007/s10519-018-9893-3 ORIGINAL RESEARCH Weighted Burden Analysis of Exome-Sequenced Case-Control Sample Implicates Synaptic Genes in Schizophrenia Aetiology David Curtis1,2 · Leda Coelewij1 · Shou‑Hwa Liu1 · Jack Humphrey1,3 · Richard Mott1 Received: 22 November 2017 / Accepted: 13 March 2018 / Published online: 21 March 2018 © The Author(s) 2018 Abstract A previous study of exome-sequenced schizophrenia cases and controls reported an excess of singleton, gene-disruptive vari- ants among cases, concentrated in particular gene sets. The dataset included a number of subjects with a substantial Finnish contribution to ancestry. We have reanalysed the same dataset after removal of these subjects and we have also included non- singleton variants of all types using a weighted burden test which assigns higher weights to variants predicted to have a greater effect on protein function. We investigated the same 31 gene sets as previously and also 1454 GO gene sets. The reduced dataset consisted of 4225 cases and 5834 controls. No individual variants or genes were significantly enriched in cases but 13 out of the 31 gene sets were significant after Bonferroni correction and the “FMRP targets” set produced a signed log p value (SLP) of 7.1. The gene within this set with the highest SLP, equal to 3.4, was FYN, which codes for a tyrosine kinase which phosphorylates glutamate metabotropic receptors and ionotropic NMDA receptors, thus modulating their trafficking, subcellular distribution and function. In the most recent GWAS of schizophrenia it was identified as a “prioritized candidate gene”. -

Parker7,23,* Type 2 diabetes (T2D) results from the combined effects of genetic and environmental factors on multiple tissues over time. Of the 4100 variants associated with T2D and related traits in genome-wide association studies (GWAS), 490% occur in non-coding regions, suggesting a strong regulatory component to T2D risk. Here to understand how T2D status, metabolic traits and genetic variation influence gene expression, we analyse skeletal muscle biopsies from 271 well-phenotyped Finnish participants with glucose tolerance ranging from normal to newly diagnosed T2D. We perform high-depth strand-specific mRNA-sequencing and dense genotyping. Computational integration of these data with epigenome data, including ATAC-seq on skeletal muscle, and transcriptome data across diverse tissues reveals that the tissue-specific genetic regulatory architecture of skeletal muscle is highly enriched in muscle stretch/super enhancers, including some that overlap T2D GWAS variants. -
Food Allergy in a Child with De Novo KAT6A Mutation Varpu Elenius1*, Tuire Lähdesmäki2, Marja Hietala3 and Tuomas Jartti1
Elenius et al. Clin Transl Allergy (2017) 7:19 DOI 10.1186/s13601-017-0155-x Clinical and Translational Allergy LETTER TO THE EDITOR Open Access Food allergy in a child with de novo KAT6A mutation Varpu Elenius1*, Tuire Lähdesmäki2, Marja Hietala3 and Tuomas Jartti1 Abstract Crying combined with miscellaneous gastrointestinal symptoms are typical symptoms of infant with food allergy, but are also common among children with abnormal neurological development. Mutations in KAT6A gene is known to cause a syndrome characterized by developmental delay, hypotonia, cardiac defects, microcephaly, specifc facial features and early feeding problems. However, these feeding problems have not earlier been specifed. We present the frst reported case of a DBPCFC confrmed food allergy in a child with KAT6A mutation whose feeding problems resolved with elimination diet. The present case does not establish proof of cause, but highlights the importance of careful clinical diagnostics despite other possible causes for feeding problems. Recognizing that early feeding prob‑ lems these patients regularly have might be caused by food allergy is important for outcome and quality of life for these patients.

Although loss of function (LoF) mutations were initially reported as causing this disorder, missense mutations, to date always involving serine residues, have recently been associated with a form of the disorder without cardiac involvement. Results: In this study we present five new patients, four with truncating mutations and one with a missense change and the only one not presenting with cardiac anomalies. The missense change [p.(Gly359Ser)], also predicted to affect splicing by in silico tools, was functionally tested in the patient’s lymphocyte RNA revealing a splicing effect for this allele that would lead to a frameshift and premature truncation. Conclusions: An extensive revision of the clinical features of these five patients revealed high concordance with the 80 cases previously reported, including developmental delay with speech delay, feeding difficulties, hypotonia, a high bulbous nose, and recurrent infections. -

Epigenome Alterations in Aortic Valve Stenosis and Its Related Left
Gošev et al. Clinical Epigenetics (2017) 9:106 DOI 10.1186/s13148-017-0406-7 REVIEW Open Access Epigenome alterations in aortic valve stenosis and its related left ventricular hypertrophy Igor Gošev1, Martina Zeljko2, Željko Đurić3, Ivana Nikolić4, Milorad Gošev5, Sanja Ivčević6, Dino Bešić7, Zoran Legčević7 and Frane Paić7* Abstract Aortic valve stenosis is the most common cardiac valve disease, and with current trends in the population demographics, its prevalence is likely to rise, thus posing a major health and economic burden facing the worldwide societies. Over the past decade, it has become more than clear that our traditional genetic views do not sufficiently explain the well-known link between AS, proatherogenic risk factors, flow-induced mechanical forces, and disease-prone environmental influences. Recent breakthroughs in the field of epigenetics offer us a new perspective on gene regulation, which has broadened our perspective on etiology of aortic stenosis and other aortic valve diseases. Since all known epigenetic marks are potentially reversible this perspective is especially exciting given the potential for development of successful and non-invasive therapeutic intervention and reprogramming of cells at the epigenetic level even in the early stages of disease progression. This review will examine the known relationships between four major epigenetic mechanisms: DNA methylation, posttranslational histone modification, ATP-dependent chromatin remodeling, and non-coding regulatory RNAs, and initiation and progression of AS. Numerous profiling and functional studies indicate that they could contribute to endothelial dysfunctions, disease-prone activation of monocyte-macrophage and circulatory osteoprogenitor cells and activation and osteogenic transdifferentiation of aortic valve interstitial cells, thus leading to valvular inflammation, fibrosis, and calcification, and to pressure overload-induced maladaptive myocardial remodeling and left ventricular hypertrophy.
