Russell-Silver-Syndrome is a rare disease and is characterized by growth retardation with antenatal onset, characteristic facies and limb asymmetry. One major clinical characteristic is relative macrocephaly. The incidence is evaluated at 1-30/100 000 cases and about 400 cases have been reported in the literature. It was first clinically described by Russel and Silver et al. in 1953/54 independ...
In 1991, Winship et al 1 described South African sibs, one male child aged 5 years and one female child aged 12 months, with a combination of microcephaly, dilated cardiomyopathy, and minor dysmorphic features. The cardiomyopathy had resolved in the older child by the age of 3 years, and had markedly improved in the younger child on treatment for associated cardiac failure. The microcephaly was...
Next generation sequencing methodologies are facilitating the rapid characterisation of novel structural variants at nucleotide resolution. These approaches are particularly applicable to variants initially identified using alternative molecular methods. We report a child born with bilateral postaxial syndactyly of the feet and bilateral fifth finger clinodactyly. This was presumed to be an aut...
BACKGROUND Kirner's deformity is a rare bony deformity that is characterized by radial and volar curvature of the distal phalanx of the fifth finger. Affected patients usually present after the age of 5 years, with girls more affected than boys and bilateral involvement more common than unilateral. CASE PRESENTATION We report a case of an eight-year-old girl who presented with progressive def...
BACKGROUND Silver-Russell syndrome (SRS) is characterised by intrauterine growth restriction, poor postnatal growth, relative macrocephaly, triangular face and asymmetry. Maternal uniparental disomy (mUPD) of chromosome 7 and hypomethylation of the imprinting control region (ICR) 1 on chromosome 11p15 are found in 5-10% and up to 60% of patients with SRS, respectively. As many features are non-...
Down’s syndrome or trisomy 21 is man’s most frequent genetic disorder. It affects one out of 600-700 live births. It is characterized by the presence of an additional chromosome at the 21 pair which elicits generalized decrease of growth as well as intellectual disability. In scientifi c literature there are many reports of cranio-facial and oral manifestations of this disorder. Chief oral cond...
We identified a novel 6.33 Mb deletion of 1q21.3q23.3 (hg18; chr1: 153035245-159367106) in two siblings presenting with blepharophimosis, ptosis, microbrachycephaly, severe psychomotor, and intellectual disability. Additional common features include small corpus callosum, normal birth length and head circumference, postnatal growth restriction, low anterior hairline, upturned nose, bilateral pr...
Silver-Russell syndrome (SRS) is a genetically heterogeneous disorder characterized by intrauterine and postnatal growth retardation, typical facial features and a spectrum of additional features including body and limb asymmetry and clinodactyly. Maternal uniparental disomy for chromosome 7 (upd(7)mat) was shown to occur in 5-10% of patients with SRS. Maternal UPD7 is clinically often associat...
The main aim of this work is to present unusual case with full trisomy 18 and additional robertsonian translocation- Rob (13;14) detected through abnormalities found in prenatal ultrasound examination. A 26 years-old pregnant women with no family history of any reproductive failure underwent level II ultrasound screening in 19 weeks of gestation. Polyhydramnios, intrauterine growth retardation,...
The propositus (Fig. 1) was the result of a 3rd pregnancy of the mother; she had had 2 phenotypically normal children from a previous marriage. The pregnancy was noted for small fetal size, lack of intrauterine movements, and recurrent small antipartum haemorrhages. Urinary oestriol excretion was low throughout the pregnancy. The child was delivered by emergency caesarean section when the mothe...
