The first Consensus Statement on Silver Russell Syndrome has been held in 2015, on behalf of the COST Action BM1208 (European Network for Human Congenital Imprinting Disorders, http://www.imprinting-disorders.eu), ESPE, PES, APPES and SLEP with the participation of five representatives from a parent support group from different countries. It has been published in 2016 (ht...

Background: Recently we described a family with several members having intrauterine and postnatal growth failure as well as signs of Silver–Russell syndrome (SRS) who carried a heterozygote nonsense mutation of IGF2. The patients had low IGF-II serum levels, but normal IGF-I serum levels.Objective and hypotheses: We aimed to estimate the diagnostic value of the IGF-II, IGF-I and IGFBP-3 measurements in the assessment of children with SRS.<p clas...

Background: Silver-Russell syndrome (SRS) is characterized by small for gestational age (SGA) birth, severe short stature and variable dysmorphic features. Children born SGA are at increased risk to develop adult-onset disease at a relatively young age. Growth hormone (GH)-treatment is a registered growth-promoting therapy for short children born SGA, including SRS. Data on metabolic health and long-term safety of GH-treatment in SRS are limited.Objectiv...

Background: Silver Russell syndrome (SRS) is an imprinting defect disease.Objective: To study clinical characteristics and imprinting defects in Chinese children with SRS.Methods: Forty-nine SRS cases were studied retrospectively. Out of these 49 cases, 36 were available to be detected chromosome 11p15 imprinting defects and 21 cases were detected uniparental disomy of maternal chromosome 7 (UPD(7) mat).Resul...

Background: Silver-Russell syndrome (SRS) is a rare congenital developmental disorder characterised by pre- and postnatal growth failure, relative macrocephaly, triangular face, hemihypotrophy, and fifth finger clinodactyly. Hypomethylation of the H19-DMR and maternal uniparental disomy chromosome 7 (UPD(7)mat) were identified in about 30 and 10% of SRS patients respectively. Genetic causes of the remaining 60% of the patients are unknown. Growth failure, small hands, and hypo...

Background: Nearly half of SRS epigenetic etiology is unknown. Effect of GH in SRS is not exact.Objective: To determine novel gene or imprinted gene associated with pathogenicity of Silver–Russell syndrome (SRS) through detection genome-wide methylation differences. To observe GH efficacy in SRS and the relationship between GH and epigenetic changes.Method: To detect genome-wide methylation site through the Illumina 450K methy...

Context: Silver-Russell syndrome (SRS) is a rare imprinting disorder responsible for foetal and postnatal growth restriction. It is a clinical diagnosis based on Netchine-Harbison clinical scoring system in patients presenting with ≥ 4 items out of 6. Some of the items in this score are not assessable until the age of two years, such as growth retardation or feeding difficulties and body asymmetry can be difficult to identify in the first months of life. Ch...

Background: Genomic imprinting is an epigenetic mechanism referring to the monoallelic silencing of genes according to their parental origin. Human chromosome 11p15.5 encompasses two imprinted domains (ICR1 and ICR2) playing an important role in controlling fetal and postnatal growth. Genetic (uniparental disomy or gain/loss of function mutations) or epigenetic alterations at the 11p15.5 imprinted region (loss or gain of DNA methylation) are associated with two clinical disord...

There is little information on metabolic profiles and Body Composition in children with Silver-Russell syndrome (SRS).Methods: 31 SRS patients [16 subjects with 11p15 loss of methylation (11pLOM) and 15 subjects with maternal uniparental disomy of chromosome 7 (mUPD7); mean age 7.4±4.3 years] and non-SRS subjects [34 small for gestational age (SGA), 13.4±2.7 years, and 44 appropriate for gestational age (AGA), 6.9 ± 1.4 ye...

Background: Genetic workup is negative in up to 40% of children presenting with clinical signs of Silver-Russell syndrome (SRS). HMGA2 variants causing SRS are rare, accounting for less than 1% of all reported cases.Case description: A 1y,8m-old boy was referred to our endocrinology institute due to severe failure to thrive (HAZ=-4.6 SDS, WAZ=-4.8 SDS) and feeding difficulties requiring nutritional support via P...
