Duplicated pituitary gland in association with other midline craniofacial anomalies – also described as DPG-plus syndrome – is extremely rare. So far the only described endocrine associations are precocious or delayed puberty. We describe the multifaceted management of a female infant with DPG-plus syndrome. Interestingly, the patient also presented with trans-cranial nasal dermoid cyst and a nasal dimple with protruding hair, which has not been described in previous...

Background: Silver-Russell syndrome (SRS) is a heterogeneous syndrome characterized by severe intrauterine and postnatal growth retardation and typical dysmorphic features. The major abnormality is the hypomethylation of paternal allele of 11p15 imprinting centre region 1. In 10% of cases a maternal uniparental disomy of chromosome 7 (UPD7) can be detected. Speech delay and learning difficulties have been reported in these patients.Objective and hypothes...

Background: Silver-Russell syndrome (SRS) is a heterogeneous condition characterized by intrauterine growth restriction, relative macrocephaly at birth, postnatal growth retardation, body asymmetry, feeding difficulties/ low body mass index and dysmorphic craniofacial features. SRS is caused by DNA hypomethylation at the H19/IGF2-imprinting control region (ICR1) on chromosome 11p15 or maternal uniparental disomy of chromosome 7 (mUPD7) in approximately 50% and 10%, respectivel...

Background: Silver-Russell syndrome (SRS) is reported to be associated with early adrenarche, but substantial studies are lacking.Objective and hypotheses: We aimed to determine the median age at onset of adrenarche, the prevalence of premature adrenarche as well as its causes and consequences.Method: Currently we have collected longitudinal data from 40 children with SRS seen during the last 20 years in our centre. The patients fu...

Background: Silver Russell syndrome (SRS) is characterized by low birth weight, severe postnatal short stature and distinctive facies. In ~50% of patients, (epi)genetic alterations can be detected (~40% hypomethylation of H19 on chromosome 11, ~10% maternal uniparental disomy (UPD) 7). As SRS patients are usually born small for gestational age (SGA), they are treated with GH to improve height. However, data on long-term effects of GH treatment in SRS patients are very limited....

Background: Silver-Russell syndrome (SRS) is characterized by intrauterine and postnatal growth retardation, relative macrocephaly at birth, prominent forehead, severe feeding difficulties and body asymmetry. In around 50%, it is secondary to hypomethylation at the IGF2/H19 imprinted locus on 11p15 (11p15 LOM), and in 10% to a maternal disomy of chromosome 7 (mUPD7). Mechanisms of postnatal growth failure in SRS are not well understood.Objective and hypo...

Background: Imprinting disease such as Prader-Willi syndrome (PWS) are associated with pathological sleep due to central and obstructive apneas. No data are available concerning Silver Russell syndrome (SRS) but most patients describe day asthenia and snoring. These patients also often present with maxillo-facial malformations.Aims and objectives: We wanted to characterise sleep in SRS and evaluate GH therapy possible effect on it....

Introduction: Silver-Russell Syndrome (SRS) is a rare genetic disease with an estimated prevalence of 1/100,000. It is characterized by the association of severe intrauterine growth retardation, postnatal failure to thrive, particular facial dysmorphism and asymmetry of the limbs. SRS is a pathology of parental imprinting. It is dependent on several imprinted genes, acting through different molecular mechanisms.Case Report:</stro...

Silver-Russell syndrome (SRS) is an epigenetic disorder characterized by severe intrauterine and postnatal growth retardation and typical dysmorphic features. The most common genetic abnormalities are 11p15 ICR1 loss of methylation, (11p15 LOM) and maternal uniparental disomy of chromosome 7 (mUPD7). There is little information on cognitive development in SRS patients and no neuroradiological studies are available so far. Global developmental delay and requirement for speech t...

Introduction: Silver-Russell syndrome (SRS) is a rare, clinically and genetically heterogenous condition, and affects one in 100,000 born children. The most well-known genetic mutations in this syndrome are: 11p15 mutation (20–60% patients), and maternal uniparental chromosome 7 disomy (7%–15%). Children with SRS have severely impaired physical growth - intrauterine and after birth. They can be treated with growth hormone (GH).Case report: 8 ye...
