Introduction: Silver–Russell Syndrome (SRS) is a heterogeneous condition characterised by low birth weight, postnatal growth failure and clinical features including relative macrocephaly, limb or facial asymmetry and a triangular facies with broad forehead, pointed chin and downturned mouth. SRS been linked to a number of genetic abnormalities including maternal uniparental disomy (UPD), of chromosome 7 and hypomethylation of the IGF2-H19 imprinted region on chromosome 11...

Von-Hippel Lindau syndrome (VHL) is a familial disorder presenting in children with a range of different neoplasia. A paediatric screening protocol was published in 2000 and has now been applied to patients in our centre. Screening for VHL is multi-disciplinary involving clinical, biochemical, and radiological investigations.Methods: Data was collected between 2000 and 2007 in 14 children on compliance with screening and identification of pathological le...

Background: Russell–Silver syndrome (RSS) is a heterogeneous condition characterised by pre- and post-natal growth retardation in association with variable dysmorphic features including triangular facies and body asymmetry. The condition has previously been linked to 2 genetic abnormalities: aberrant methylation at the 11p15.5 locus in 30–40% and maternal uniparental disomy (UPD) of chromosome 7 in 10% of cases. Up to 50% of children currently have no identified (epi...

A number of single nucleotide polymorphisms (SNPs) have been identified in the GHRH receptor gene. Two of these SNPs, A57T and V225I, have been found to cause an increased cAMP response to GHRH stimulation in vitro, and it has been suggested that they may be associated with the abnormal biochemistry in patients with somatotroph adenomas. The objective of this study was to clarify the frequencies of these SNPs in the normal population and in subjects with short stature. The sub...

Background: Mutations in succinate dehydrogense-B (SDH-B) or von Hippel Lindau (VHL) genes can result in chromaffin tumours.Objective: To compare the clinical phenotypes of subjects developing chromaffin tumours as a result of SDH-B or VHL mutations.Subjects: Thirty-one subjects with chromaffin tumours. Sixteen subjects had SDH-B gene mutations and 15 subjects had a diagnosis of VHL.<p ...
