Russell-Silver syndrome is a heterogeneous disorder characterized by intrauterine growth retardation, postnatal growth deficiency, characteristic facial appearance, and other variable features. Genetic and epigenetic alterations are identified in about 60% of individuals with Russell-Silver syndrome. Most frequently, Russell-Silver syndrome is caused by altered gene expression on chromosome 11p15 due to loss of methylation at the telomeric imprinting center. To date there have been a handful of isolated clinical reports implicating the centromeric imprinting center 2 in the etiology of Russell-Silver syndrome...

Russell-Silver syndrome (RSS) is a type of primordial dwarfism. Only one case of testicular cancer in RSS has been reported, the pathology of which was nonseminoma. Here, we report a case of seminoma in a 36-year-old man who was diagnosed with RSS at birth. The seminoma was diagnosed when the patient presented with testicular torsion. This is the first report of testicular seminoma in an RSS patient in the literature. We also discussed the correlation between seminoma and RSS.

In this issue of Genes & Development, Ginart and colleagues (pp. 567-578) study a mouse model for Russell-Silver syndrome (RSS) and show that similar cells within one individual can display distinct gene expression patterns because of epigenetic marks that are established stochastically during early development. Their results provide an excellent explanation for phenotypes seen in RSS and other imprinting disorders and especially help us understand how patients with similar or even identical genetic mutations can display distinct disease profiles...

Russell-Silver syndrome (RSS) is a congenital anomaly characterized by intrauterine and postnatal growth retardation, typical facial features, fifth-finger clinodactyly, and skeletal asymmetry. Although data on intrauterine and postnatal growth retardation have been reported, there are few reports concerning the typical maxillofacial morphology in individuals with RSS. The aim of this study was to describe the details of this systemic condition and to characterize maxillofacial morphology based on cephalograms in 11 Japanese patients (age range, 3...

Temple syndrome (TS, MIM 616222) is an imprinting disorder involving genes within the imprinted region of chromosome 14q32. TS is a genetically complex disorder, which is associated with maternal uniparental disomy of chromosome 14 (UPD14), paternal deletions on chromosome 14, or loss of methylation at the intergenic differentially methylated region (IG-DMR). Here, we describe the case of a patient with maternal hetero-UPD14, mixed iso-/hetero-disomy mechanism identified by a single nucleotide polymorphism (SNP) array analysis of patient-father duos study...

Five cases of recognizable "Intra-uterine" dwarfism with cranio-facial dysostosis, disproportionately short arms, and other anomalies were written up by endocrinologist, Dr. Alex Russell in 1954. The syndrome he described went on to be named Russell-Silver syndrome. This report gives further information about the life and medical history of the most pictorially documented boy that Dr. Russell originally described in his seminal paper. The gentleman is now 69 years old and we believe him to be the oldest person known to date to have Russell-Silver syndrome...

Developmental Origins of Health and Disease theory stems from large-scale epidemiologic observation. The presumed mechanism for this hypothesis includes epigenetic changes; however, it remains to be elucidated if individuals with intrauterine growth retardation and epigenetic changes confirmed at the molecular level are indeed susceptible to adult-onset disease. Here we document three individuals with Russell-Silver syndrome, a prototypic condition caused by hypomethylation of the differently methylated imprinting center region 1 (ICR1) between the IGF2 and H19 loci on chromosome 11p15...

The authors describe the case of a 32-year-old woman known to have Russell-Silver syndrome who presented with repeated aneurysmal subarachnoid hemorrhage. Multiple intracranial aneurysms and advanced peripheral vascular disease were demonstrated. The authors postulate a link between these vascular features and the patient's genetic condition.

BACKGROUND: The structural organisation of the human IGF2/ICR1/H19 11p15 domain is very complex, and the mechanisms underlying its regulation are poorly understood. The Imprinted Center Region 1 (ICR1) contains seven binding sites for the zinc-finger protein CTCF (CBS: CTCF Binding Sites); three additional differentially methylated regions (DMR) are located at the H19 promoter (H19DMR) and two in the IGF2 gene (DMR0 and DMR2), respectively. Loss of imprinting at the IGF2/ICR1/H19 domain results in two growth disorders with opposite phenotypes: Beckwith-Wiedemann syndrome and Russell Silver syndrome (RSS)...

Russell-Silver Syndrome (RSS) is a prenatal and postnatal growth retardation syndrome caused mainly by 11p15 ICR1 hypomethylation. Clinical presentation is heterogeneous in RSS patients with 11p15 ICR1 hypomethylation. We previously identified a subset of RSS patients with 11p15 ICR1 and multilocus hypomethylation. Here, we examine the relationships between IGF2 expression, 11p15 ICR1 methylation, and multilocus imprinting defects in various cell types from 39 RSS patients with 11p15 ICR1 hypomethylation in leukocyte DNA...

Overgrowth syndromes comprise a diverse group of conditions with unique clinical, behavioral and molecular genetic features. While considerable overlap in presentation sometimes exists, advances in identification of the precise etiology of specific overgrowth disorders continue to improve clinicians' ability to make an accurate diagnosis. Among them, this paper introduces two classic genetic overgrowth syndromes: Sotos syndrome and Beckwith-Wiedemann syndrome. Historically, the diagnosis was based entirely on clinical findings...

Dilated cardiomyopathy is characterised by dilation and impaired systolic function. We present the case of a child with dilated cardiomyopathy caused by a 624 kb duplication of 6q22.31, which includes the phospholamban gene. The patient also has failure to thrive and developmental delay due to complex cytogenetic abnormalities including a 5p15 deletion associated with Cri du Chat and an 11p15 duplication associated with Russell-Silver syndrome.

INTRODUCTION/BACKGROUND: Russell-Silver syndrome (RSS) is the combination of intrauterine growth retardation, difficulty feeding, and postnatal growth retardation. Leg length discrepancy (LLD) is one of four major diagnostic criteria of RSS and is present in most cases. We aimed to ascertain whether pediatric RSS patients will adequately consolidate bony regenerate following leg lengthening. MATERIALS AND METHODS: We retrospectively reviewed pediatric RSS patients who underwent limb lengthening and compared them to a similar group of patients with LLD resulting from tumor, trauma, or congenital etiology...

PURPOSE OF REVIEW: The imprinted human 11p15.5 region encompasses two imprinted domains important for the control of fetal growth: the H19/IGF2 domain in the telomeric region and the KCNQ1OT1/CDKN1C domain in the centromeric region. These two domains are differentially methylated and each is regulated by its own imprinting control region (ICR): ICR1 in the telomeric region and ICR2 in the centromeric region. Aberrant methylation of the 11p15.5 imprinted region, through genetic or epigenetic mechanisms, leads to two clinical syndromes, with opposite growth phenotypes: Russell-Silver Syndrome (RSS; with severe fetal and postnatal growth retardation) and Beckwith-Wiedemann Syndrome (BWS; an overgrowth syndrome)...

INTRODUCTION: Russell-Silver Syndrome (RSS) is a genetically determined condition characterized by severe intrauterine and postnatal growth retardation; relative macrocephaly; a small, triangular face; and fifth-finger clinodactyly. The etiology of RSS involves epigenetic regulation through either uniparental disomy or genomic imprinting via DNA methylation. There has been no documented association between RSS and cardiomyopathy. METHODS: We present an original case of a 32-year-old woman with RSS with dilated a cardiomyopathy who on cardiac biopsy showed occasional hypertrophic and atrophic myocytes with no evidence of inflammation, abnormal sarcomeres and disintegration of the Z bands on ultrastructural analysis, abnormal desmin, and normal C9 immunoreactivity...

BACKGROUND: Russell Silver syndrome (RSS) leads to prenatal and postnatal growth retardation. About 55% of RSS patients present a loss-of-methylation of the paternal ICR1 domain on chromosome 11p15. CDKN1C is a cell proliferation inhibitor encoded by an imprinted gene in the 11p15 ICR2 domain. CDKN1C mutations lead to Beckwith Wiedemann syndrome (BWS, overgrowth syndrome) and in IMAGe syndrome which associates growth retardation and adrenal insufficiency. We searched for CDKN1C mutations in a cohort of clinically diagnosed RSS patients with no molecular anomaly...

Fetal growth is a complex process involving environmental, epigenetic and genetic factors. Fetal growth restriction is associated with morbidity among small for gestational age (SGA) neonates as well as in children and adults who were former SGA. Imprinted genes (whose expression is restricted to a single parental allele) have a critical role in controlling mammalian fetal growth. The human chromosome 11p15 encompasses two imprinted domains regulated by their own differentially methylated imprinted control region (ICR1 at the H19/IGF2 domain, and ICR2 at the KCNQ1/CDKN1C domain)...
