Bottom-up mass spectrometry (MS) can identify histone PTMs, whereas intact protein analysis by MS can detect species missed by bottom-up approaches. We used a novel approach of online two-dimensional liquid chromatography-tandem MS with high-resolution reversed-phase liquid chromatography (RPLC), alternating electron transfer dissociation (ETD) and collision-induced dissociation (CID) on precursor ions to maximize fragmentation of uniquely modified species. The first online RPLC separation sorted histone families, then RPLC or weak cation exchange hydrophilic interaction liquid chromatography (WCX-HILIC) separated species heavily clad in PTMs. Tentative identifications were assigned by matching proteoform masses to predicted theoretical masses that were verified with tandem MS. We used this innovative approach for histone-intact protein PTM mapping (HiPTMap) to identify and quantify proteoforms purified from CD8 T cells after in vivo influenza infection. -
Next Generation Sequencing Panels for Disorders of Sex Development
Next Generation Sequencing Panels for Disorders of Sex Development Disorders of Sex Development – Overview Disorders of sex development (DSDs) occur when sex development does not follow the course of typical male or female patterning. Types of DSDs include congenital development of ambiguous genitalia, disjunction between the internal and external sex anatomy, incomplete development of the sex anatomy, and abnormalities of the development of gonads (such as ovotestes or streak ovaries) (1). Sex chromosome anomalies including Turner syndrome and Klinefelter syndrome as well as sex chromosome mosaicism are also considered to be DSDs. DSDs can be caused by a wide range of genetic abnormalities (2). Determining the etiology of a patient’s DSD can assist in deciding gender assignment, provide recurrence risk information for future pregnancies, and can identify potential health problems such as adrenal crisis or gonadoblastoma (1, 3). Sex chromosome aneuploidy and copy number variation are common genetic causes of DSDs. For this reason, chromosome analysis and/or microarray analysis typically should be the first genetic analysis in the case of a patient with ambiguous genitalia or other suspected disorder of sex development. Identifying whether a patient has a 46,XY or 46,XX karyotype can also be helpful in determining appropriate additional genetic testing. Abnormal/Ambiguous Genitalia Panel Our Abnormal/Ambiguous Genitalia Panel includes mutation analysis of 72 genes associated with both syndromic and non-syndromic DSDs. This comprehensive panel evaluates a broad range of genetic causes of ambiguous or abnormal genitalia, including conditions in which abnormal genitalia are the primary physical finding as well as syndromic conditions that involve abnormal genitalia in addition to other congenital anomalies. -

Towards Mutation-Specific Precision Medicine in Atypical Clinical
International Journal of Molecular Sciences Review Towards Mutation-Specific Precision Medicine in Atypical Clinical Phenotypes of Inherited Arrhythmia Syndromes Tadashi Nakajima * , Shuntaro Tamura, Masahiko Kurabayashi and Yoshiaki Kaneko Department of Cardiovascular Medicine, Gunma University Graduate School of Medicine, Maebashi 371-8511, Gunma, Japan; [email protected] (S.T.); [email protected] (M.K.); [email protected] (Y.K.) * Correspondence: [email protected]; Tel.: +81-27-220-8145; Fax: +81-27-220-8158 Abstract: Most causal genes for inherited arrhythmia syndromes (IASs) encode cardiac ion channel- related proteins. Genotype-phenotype studies and functional analyses of mutant genes, using heterol- ogous expression systems and animal models, have revealed the pathophysiology of IASs and enabled, in part, the establishment of causal gene-specific precision medicine. Additionally, the utilization of induced pluripotent stem cell (iPSC) technology have provided further insights into the patho- physiology of IASs and novel promising therapeutic strategies, especially in long QT syndrome. It is now known that there are atypical clinical phenotypes of IASs associated with specific mutations that have unique electrophysiological properties, which raises a possibility of mutation-specific precision medicine. In particular, patients with Brugada syndrome harboring an SCN5A R1632C mutation exhibit exercise-induced cardiac events, which may be caused by a marked activity-dependent loss of R1632C-Nav1.5 availability due to a marked delay of recovery from inactivation. This suggests that the use of isoproterenol should be avoided. Conversely, the efficacy of β-blocker needs to be examined. Patients harboring a KCND3 V392I mutation exhibit both cardiac (early repolarization syndrome and Citation: Nakajima, T.; Tamura, S.; paroxysmal atrial fibrillation) and cerebral (epilepsy) phenotypes, which may be associated with a Kurabayashi, M.; Kaneko, Y. -

The Genetic Basis for Skeletal Diseases
insight review articles The genetic basis for skeletal diseases Elazar Zelzer & Bjorn R. Olsen Harvard Medical School, Department of Cell Biology, 240 Longwood Avenue, Boston, Massachusetts 02115, USA (e-mail: [email protected]) We walk, run, work and play, paying little attention to our bones, their joints and their muscle connections, because the system works. Evolution has refined robust genetic mechanisms for skeletal development and growth that are able to direct the formation of a complex, yet wonderfully adaptable organ system. How is it done? Recent studies of rare genetic diseases have identified many of the critical transcription factors and signalling pathways specifying the normal development of bones, confirming the wisdom of William Harvey when he said: “nature is nowhere accustomed more openly to display her secret mysteries than in cases where she shows traces of her workings apart from the beaten path”. enetic studies of diseases that affect skeletal differentiation to cartilage cells (chondrocytes) or bone cells development and growth are providing (osteoblasts) within the condensations. Subsequent growth invaluable insights into the roles not only of during the organogenesis phase generates cartilage models individual genes, but also of entire (anlagen) of future bones (as in limb bones) or membranous developmental pathways. Different mutations bones (as in the cranial vault) (Fig. 1). The cartilage anlagen Gin the same gene may result in a range of abnormalities, are replaced by bone and marrow in a process called endo- and disease ‘families’ are frequently caused by mutations in chondral ossification.

Semin Neurol 2015;35:277–287. Abstract Megalencephaly is a developmental disorder characterized by brain overgrowth secondary to increased size and/or numbers of neurons and glia. These disorders can be divided into metabolic and developmental categories based on their molecular etiologies. Metabolic megalencephalies are mostly caused by genetic defects in cellular metabolism, whereas developmental megalencephalies have recently been shown to be caused by alterations in signaling pathways that regulate neuronal replication, growth, and migration. These disorders often lead to epilepsy, developmental disabilities, and Keywords behavioral problems; specific disorders have associations with overgrowth or abnor- ► megalencephaly malities in other tissues.

Saethre-Chotzen Syndrome
Saethre-Chotzen syndrome Authors: Professor L. Clauser1 and Doctor M. Galié Creation Date: June 2002 Update: July 2004 Scientific Editor: Professor Raoul CM. Hennekam 1Department of craniomaxillofacial surgery, St. Anna Hospital and University, Corso Giovecca, 203, 44100 Ferrara, Italy. [email protected] Abstract Keywords Disease name and synonyms Excluded diseases Definition Prevalence Management including treatment Etiology Diagnostic methods Genetic counseling Antenatal diagnosis Unresolved questions References Abstract Saethre-Chotzen Syndrome (SCS) is an inherited craniosynostotic condition, with both premature fusion of cranial sutures (craniostenosis) and limb abnormalities. The most common clinical features, present in more than a third of patients, consist of coronal synostosis, brachycephaly, low frontal hairline, facial asymmetry, hypertelorism, broad halluces, and clinodactyly. The estimated birth incidence is 1/25,000 to 1/50,000 but because the phenotype can be very mild, the entity is likely to be underdiagnosed. SCS is inherited as an autosomal dominant trait with a high penetrance and variable expression. The TWIST gene located at chromosome 7p21-p22, is responsible for SCS and encodes a transcription factor regulating head mesenchyme cell development during cranial tube formation. Some patients with an overlapping SCS phenotype have mutations in the FGFR3 (fibroblast growth factor receptor 3) gene; especially the Pro250Arg mutation in FGFR3 (Muenke syndrome) can resemble SCS to a great extent.

The Genetic Heterogeneity of Brachydactyly Type A1: Identifying the Molecular Pathways
The genetic heterogeneity of brachydactyly type A1: Identifying the molecular pathways Lemuel Jean Racacho Thesis submitted to the Faculty of Graduate Studies and Postdoctoral Studies in partial fulfillment of the requirements for the Doctorate in Philosophy degree in Biochemistry Specialization in Human and Molecular Genetics Department of Biochemistry, Microbiology and Immunology Faculty of Medicine University of Ottawa © Lemuel Jean Racacho, Ottawa, Canada, 2015 Abstract Brachydactyly type A1 (BDA1) is a rare autosomal dominant trait characterized by the shortening of the middle phalanges of digits 2-5 and of the proximal phalange of digit 1 in both hands and feet. Many of the brachymesophalangies including BDA1 have been associated with genetic perturbations along the BMP-SMAD signaling pathway. The goal of this thesis is to identify the molecular pathways that are associated with the BDA1 phenotype through the genetic assessment of BDA1-affected families. We identified four missense mutations that are clustered with other reported BDA1 mutations in the central region of the N-terminal signaling peptide of IHH. We also identified a missense mutation in GDF5 cosegregating with a semi-dominant form of BDA1. In two families we reported two novel BDA1-associated sequence variants in BMPR1B, the gene which codes for the receptor of GDF5. In 2002, we reported a BDA1 trait linked to chromosome 5p13.3 in a Canadian kindred (BDA1B; MIM %607004) but we did not discover a BDA1-causal variant in any of the protein coding genes within the 2.8 Mb critical region. To provide a higher sensitivity of detection, we performed a targeted enrichment of the BDA1B locus followed by high-throughput sequencing.
