"Russell Silver Syndrome"

Mami Shiraishi, Katsuaki Mishima, Hirotsugu Umeda
BACKGROUND: Russell-Silver syndrome (RSS) is characterized by intrauterine growth retardation, short stature without postnatal catch-up growth, and an inverted triangular face with relative macrocephaly. There have been few case reports of RSS with cleft palate, in which perioperative problems such as difficult intubation due to trismus and impossibility to wear a mouth gag due to growth failure of the mandible were described. The case of a female RSS patient with cleft palate who underwent palatoplasty is reported...

The disturbances of the 11p15.5 chromosomal region are associated with Beckwith-Wiedemann syndrome, Russell-Silver syndrome, Wilms tumor, IMAGe syndrome, and idiopathic hemihyperplasia. The aim of this research was to examine the hypothesis that 11p15.5 initially became unstable in the European population about 200 years ago. The medical literature from 1557 onwards, especially treatises on teratology, body asymmetry, and books of normal and pathologic anatomy, was searched for any mentioning of lateral body asymmetry, macroglossia and other possible visually detectable symptoms associated with the above-mentioned syndromes...

CDKN1C is a cyclin-dependent kinase Inhibitor and negative regulator of cellular proliferation. Recently, gain-of-function mutations in the PCNA domain of CDKN1C have been reported as the genetic basis of various growth-retarded syndromes including IMAGe syndrome, Russell Silver syndrome as well as a novel undergrowth syndrome that additionally exhibited early adulthood onset diabetes. This review summarizes the key clinical features and the molecular advances that have contributed to our understanding of this complex phenotypic spectrum...

Russell-Silver syndrome is a rare heterogeneous disorder mainly characterized by intrauterine and postnatal growth retardation, craniofacial disproportion, clinodactyly, variation in urogenital development, and skeletal asymmetry. It is rare to come across tethered cord-associated Russell-Silver syndrome. We report a rare case of Russell-Silver syndrome associated with low conus medullaris in a 2-year-old patient with demonstrative phenotype. Magnetic resonance imaging indicated a low conus medullaris at the inferior border of the L3 vertebral body...

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...

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.
