Beckwith-Wiedemann syndrome (BWS) is a congenital overgrowth disorder associated with abnormalities in 11p15.5 imprinted genes. The most common cause is loss of methylation (epimutation) at the imprinting control centre 2 (IC2/KvDMR1). Most IC2 epimutations occur sporadically but an association with conception after assisted reproductive technologies (ART)(More)
Water movements, of both abiotic and biotic origin, provide a wealth of information of direct relevance to the guidance of prey capture behavior. To gather hydrodynamic information, fish have sensors of two basic types: those scattered over the surface of the body known as superficial neuromasts and similar sensors embedded in subdermal lateral line canals.(More)
BACKGROUND Haploinsufficiency of PMP22 causes hereditary neuropathy with liability to pressure palsies. However, the biological functions of the PMP22 protein in humans have largely been unexplored owing to the absence of patients with PMP22-null mutations. OBJECTIVE To investigate the function of PMP22 in the peripheral nervous system by studying a boy(More)
Software inspection is an eeective method of defect detection. R e c ent research activity has considered the development of tool support to further increase the eeciency and eeectiveness of inspection, r esulting in a number of prototype t o ols being developed. However, no comprehensive evaluations of these tools have been carried out to determine their(More)
BACKGROUND Silver-Russell syndrome (SRS) is characterised by intrauterine growth restriction, poor postnatal growth, relative macrocephaly, triangular face and asymmetry. Maternal uniparental disomy (mUPD) of chromosome 7 and hypomethylation of the imprinting control region (ICR) 1 on chromosome 11p15 are found in 5-10% and up to 60% of patients with SRS,(More)
Beckwith-Wiedemann syndrome (BWS), a congenital overgrowth disorder with variable expressivity and a predisposition to tumorigenesis, results from disordered expression and/or function of imprinted genes at chromosome 11p15.5. There are no generally agreed clinical diagnostic criteria, with molecular studies commonly performed to confirm diagnosis. In(More)
Although X-linked myotubular myopathy (XLMTM) is a recessive disorder, heterozygous female carriers of MTM1 mutations may present with limb girdle and facial weakness. It is proposed that manifesting heterozygote females with XLMTM have a skewed pattern of X-chromosome inactivation. However, skewed X-chromosome inactivation was not detected in either the(More)
CONTEXT P450 oxidoreductase deficiency (PORD) is a unique congenital adrenal hyperplasia variant that manifests with glucocorticoid deficiency, disordered sex development (DSD), and skeletal malformations. No comprehensive data on genotype-phenotype correlations in Caucasian patients are available. OBJECTIVE The objective of the study was to establish(More)
Haemangioblastomas of the CNS are a cardinal feature of von Hippel-Lindau (VHL) disease, a dominantly inherited multisystem familial cancer syndrome caused by germline mutation of the VHL tumour suppressor gene. We investigated the frequency of VHL mutations in 188 patients presenting with a single haemangioblastoma, no family history of VHL disease and no(More)
