Extractions: Silver-Russell syndrome (SRS) is characterized primarily by intrauterine and postnatal growth restriction, triangular facies, and facial, limb or truncal asymmetry. Maternal uniparental disomy for chromosome 7 (mUPD7) has been identified in about 7% of SRS patients in our cohort (1). The recent demonstration of consistent heterodisomy for the entire chromosome 7 in a group of five mUPD7 cases indicates that altered expression of an imprinted gene (or genes) is the most likely cause of SRS is this category of patients (2). The region on human 7pl1.2-12 contains the epidermal growth factor receptor (EGFR) growth factor bound protein 10 (GRB10) and insulin-like growth factor binding proteins 1 (IGFBP1) and insulin-like growth factor binding proteins genes. This region is syntenic to proximal mouse chromosome 11, which demonstrates a growth-related imprinting phenotype. Any involvement of the

The etiology of the syndrome is heterogeneous and there is no clearly established Mendelian basis. However, maternal uniparental disomy of chromosome 7 (mUPD7) has been demonstrated in approximately 7% of all cases (1). These findings indicate that one or more genes on chromosome 7 maybe imprinted and involved in the pathogenesis of the syndrome. We have identified a de novo duplication of 7p11.2-p12 in a patient with features characteristic of SRS. Fluorescent in situ hybridization (FISH) confirmed the presence of a tandem duplication encompassing the SRS candidate gene

Staff Uniparental Disomy 7 Screen (Silver-Russell) DESCRIPTION: REASONS FOR REFERRAL Appropriate testing for short stature with intrauterine growth retardation, with or without developmental delay, and of unknown cause This is a DNA test to examine tetranucleotide repeat polymorphisms on chromosome 7 in a patient and parents. Normal biparental inheritance rules out the presence of uniparental disomy in the patient. If the patient lacks alleles from one parent at informative loci, other chromosomes are examined to confirm parentage. This is not a diagnostic test for Silver-Russell syndrome This test detects or rules out one possible mechanism causing that syndrome.

Extractions: As the Academic Liaison Officer for the BSPED, it is my responsibility to put together a competitive bid against other constituent societies of the BES for topics for stand-alone lectures, symposia, clinical management workshops or "what would the expert do" sessions for the proposed BES meeting in 2004 which is joint with the European Federation of Endocrine Societies in Brighton. If any of you have any burning topics that you would like to see given an airing at this meeting, I would be grateful if you would email me a list of suggested speakers, titles of proposed talks and contact details so that I might pull these ideas together into a strong bid. I would be grateful for your thoughts before the middle of July. Please respond to this message as the better our ideas, the stronger the bid and the greater likelihood we will have of getting more paediatric content in future BES meetings.

Extractions: chromosomal Mosaicism HOME TABLE OF CONTENTS SEARCH BACKGROUND ... GLOSSARY Chromosome specific Trisomy TRISOMY 7 MOSAICISM Complete trisomy 7 has never been reported in a liveborn child. Trisomy 7 is one of the most common aneuploidies detected on chorionic villus sampling . In general, prenatal detection of trisomy 7 is associated with a good outcome. However maternal UPD 7 is strongly associated with severe growth restriction placenta (CPM) appears to be primarily of mitotic origin, resulting from somatic duplication of chromosome 7. This explains the generally good outcome in the majority of cases. Given the mitotic origin the risk of fetal UPD 7 is low. Kalousek et al (1996) showed that CPM for trisomy 7 with biparental inheritance has no adverse effect on fetal growth. Thus, CVS alone is a poor predictor of pregnancy outcome for trisomy 7. When CVS is combined with DNA studies to reveal the origin of CPM (mitotic or meiotic) and parental origin of the chromosome 7s, a more reliable prediction for pregnancy outcome can be discussed (Kalousek et al, 1996). X Y Monosomy X Triploidy / Tetraploidy Trisomy 7 detected on CVS Sachs et al (1990) reported on 5 cases of trisomy 7 mosaicism. In these cases the percentage of abnormal cells measured on CVS direct studies ranged from 5%-68%. In all 5 cases the pregnancies resulted in a normal outcome.
