Abstract
Bloom syndrome (BS) is a genomic and chromosomal instability disorder with prodigious cancer predisposition caused by pathogenic variants in BLM. We report the clinical and genetic details of a boy who first presented with infantile fibrosarcoma (IFS) at the age of 6 months and subsequently was diagnosed with BS at the age of 9 years. Molecular analysis identified the pathogenic germline BLM sequence variants (c.1642C>T and c.2207_2212delinsTAGATTC). This is the first report of IFS related to BS, for which we show that both BLM alleles are maintained in the tumor and demonstrate a TPM3-NTKR1 fusion transcript in the IFS. Our communication emphasizes the importance of long-term follow up after treatment for pediatric neoplastic conditions, as clues to important genetic entities might manifest later, and the identification of a heritable tumor predisposition often leads to changes in patient surveillance and management.

Abstract
Bloom syndrome (BS) is an inherited genomic instability disorder caused by disruption of the BLM helicase and confers an extreme cancer predisposition. Here we report on a girl with BS who developed acute lymphoblastic leukaemia (ALL) at age nine, and treatment-related acute myeloid leukaemia (t-AML) aged 12. She was compound heterozygous for the novel BLM frameshift deletion c.1624delG and the previously described c.3415C>T nonsense mutation. Two haematological malignancies in a child with BS imply a fundamental role for BLM for normal haematopoiesis, in particular in the presence of genotoxic stress.

Abstract
The Rapid Syndrome Validation Project (RSVP) is a collaboration of several institutions: Sandia and Los Alamos National Laboratories, the University of New Mexico Department of Emergency Medicine, and the NM Department of Health Office of Epidemiology. RSVP is a system that operates at the intersection of individual health care providers, public health and bioterrorism. Physicians quickly enter clinical and demographic information on patients exhibiting symptoms and signs of the syndromes of interest. It provides early warning and response to emerging biological threats, as well as emerging epidemics and diseases. RSVP provides real time clinical information to the provider and any other potential user such as the DOH, about current symptoms, disease prevalence and location. The system also serves as a mechanism for the Department of Health to inform health care providers of health alerts and to facilitate the process of collecting data on reportable diseases. We describe here the purpose an the architecture of a network-based surveillance system that is currently implemented in an Emergency Department.

Abstract
The norepinephrine transporter (NET) plays a critical role in brain norepinephrine homeostasis and is a target for antidepressants and drugs of abuse. We have analyzed the 5'-flanking regulatory region of the human NET gene (SLC6A2). Primer extension and 5' RACE revealed a single transcription start site, alternative splicing of exon 1 due to alternate splice donor usage, and a variable splice acceptor of intron 1. A TA-rich motif 35 bp upstream of the transcription start and several potential binding sites for transcription factors including a cAMP response element (CRE)-like motif are present in the 5'-flanking region. A 4.0-kb fragment, which had been fused to the luciferase reporter gene and transiently expressed in a NET+ cell line, displayed both constitutive and inducible promoter activity. Functional analysis by serial deletions revealed several clusters of cell-selective enhancer elements. Our findings indicate that (1) the NET gene promoter is active in NET-expressing cells and the information contained within approximately 4 kb of the 5'-flanking sequence is required to confer its cell-selective expression, (2) the expression of NET is regulated by a combination of positive cis-acting elements operating through a basal promoter defined by a TA-rich motif, and (3) the promoter responds to cAMP-dependent induction. Fusion of the human NET gene promoter to selected genes will facilitate their cell-selective expression in gene transfer strategies.
