Wiedemann-Steiner syndrome is a rare genetic disorder characterized by short stature, hairy elbows, facial dysmorphism, and developmental delay. It can also be accompanied by musculoskeletal anomalies such as muscular hypotonia and small hands and feet. Mutations in the KMT2A gene have only recently been identified as the cause of Wiedemann-Steiner syndrome; therefore, only 16 patients from 15 families have been described, and new phenotypic features continue to be added. In this report, we describe 2 newly identified patients with Wiedemann-Steiner syndrome who presented with variable severity...

INTRODUCTION: The Rubinstein-Taybi syndrome and pancreas divisum are uncommon diseases in children. The Rubinstein-Taybi syndrome diagnosis is only clinical, and mental retardation and dysmorphic features mainly characterize it. The PD relates to idiopathic pancreatitis in 7.5% of patients suffering from this disorder. It has not been found any cases reported where these diseases are associated and the management of patients with pancreatitis associated with PD is still a challenge. CLINICAL CASE: A patient diagnosed with Rubinstein-Taybi syndrome has recurrent abdominal pain of six months and elevated pancreatic enzymes, he underwent a magnetic resonance imaging where pancreas divisum is suspected...

1p36 deletion syndrome is the most common terminal deletion syndrome, and the genomic regions that contribute to specific 1p36 deletion syndrome-related phenotypes were recently identified. Deletions in the 1p36 region have been documented in various tumor tissues, which indicates correlation between loss of heterozygosity of 1p36 and tumor development, and the existence of tumor suppressors in this region. Therefore, it was suspected that patients with 1p36 deletion syndrome have a higher risk of tumor development; however, only a few child cases of neuroblastoma with 1p36 deletion syndrome have been reported...

The SATB2-associated syndrome is a recently described syndrome characterized by developmental delay/intellectual disability with absent or limited speech development, craniofacial abnormalities, behavioral problems, dysmorphic features, and palatal and dental abnormalities. Alterations of the SATB2 gene can result from a variety of different mechanisms that include contiguous deletions, intragenic deletions and duplications, translocations with secondary gene disruption, and point mutations. The multisystemic nature of this syndrome demands a multisystemic approach and we propose evaluation and management guidelines...

Glycine is a major neurotransmitter that activates inhibitory glycine receptors and is a co-agonist for excitatory glutamatergic N-methyl-D-aspartate (NMDA) receptors. Two transporters, GLYT1 and GLYT2, regulate extracellular glycine concentrations within the CNS. Dysregulation of the extracellular glycine has been associated with hyperekplexia and nonketotic hyperglycinemia. Here, we report four individuals from two families who presented at birth with facial dysmorphism, encephalopathy, arthrogryposis, hypotonia progressing to hypertonicity with startle-like clonus, and respiratory failure...

Tat-interactive protein 60 (Tip60), encoded by the Kat5 gene, is a member of the MYST family of acetyltransferases. Cancer biology studies have shown that Tip60 induces the DNA damage response, apoptosis, and cell-cycle inhibition. Although Tip60 is expressed in the myocardium, its role in cardiomyocytes (CMs) is unclear. Earlier studies here showed that application of cardiac stress to globally targeted Kat5+/-haploinsufficient mice resulted in inhibition of apoptosis and activation of the CM cell-cycle, despite only modest reduction of Tip60 protein levels...

BACKGROUND: Epilepsy is genetically complex but common brain disorder of the world affecting millions of people with almost of all age groups. Novel Copy number variations (CNVs) are considered as important reason for the numerous neurodevelopmental disorders along with intellectual disability and epilepsy. DNA array based studies contribute to explain a more severe clinical presentation of the disease but interoperation of many detected CNVs are still challenging. RESULTS: In order to study novel CNVs with epilepsy related genes in Saudi family with six affected and two normal individuals with several forms of epileptic seizures, intellectual disability (ID), and minor dysmorphism, we performed the high density whole genome Agilent sure print G3 Hmn CGH 2x 400 K array-CGH chips analysis...

INTRODUCTION: RASopathies include disorders generally characterized by developmental delay, specific heart defects, short stature, cardiac hypertrophy, and facial dysmorphisms. Next-generation sequencing (NGS)-based panels have widespread acceptance as a diagnostic tool for RASopathies. MATERIALS AND METHODS: The first 126 patients evaluated by clinical examination and the NGS RASopathy panel at the Children's Hospital of Philadelphia were enrolled. We calculated diagnosis rate, correlated reported clinical findings with positive or negative test results, and identified final molecular diagnoses in 28/96 patients who tested negative for RASopathies...

Body dysmorphic disorder (BDD) is associated with elevated suicidality. Little is known about why BDD patients are at increased risk. The interpersonal-psychological theory of suicide (IPTS) could clarify suicidality in BDD, and theorizes that perceived burdensomeness and thwarted belongingness lead to suicidal desire, while an acquired capability for suicide is necessary to attempt suicide. No study has investigated how BDD symptoms relate to IPTS constructs or mediators of the relationship between BDD and suicidality...

Partial trisomy of the short arm of chromosome 6 is a rare and clinically distinct syndrome. The breakpoints have been found to be variable ranging from bands 6p11 to 6p25. This study reports partial trisomy for 6p22.3→pter in a 2-year-old boy referred with a complaint of developmental delay and facial dysmorphism. Conventional cytogenetic analysis showed the presence of an abnormal chromosome 5 resulting from an unbalanced translocation in the proband. Array comparative genomic hybridization revealed trisomy of distal 6p which was confirmed by fluorescence in situ hybridization using subtelomeric probes for chromosomes 5 and 6...

We report on a patient with a 6.5 Mb interstitial de novo deletion in 3q24q25.2, characterized by array CGH. The patient is a 4-year and 2-month-old girl, who presented to us with mild developmental delay, absence of language, facial dysmorphism, hirsutism, strabismus, and Dandy-Walker Malformation. The main clinical signs typical of WS (Wisconsin syndrome) are evident in the patient. The molecular mapping of WS in 3q23q25 allowed geneticists to define the syndrome more accurately. Comparing the present patient's phenotype with that of cases with a molecular characterization so far reported, it was possible to narrow the critical region for WS to an interval of 750 Kb, where two genes (MBNL1 and TMEM14E) are harbored...

Heterozygous germline mutations in MTOR have been shown to underlie Smith-Kingsmore syndrome, a rare autosomal dominant syndrome characterized by macrocephaly, developmental delay, and dysmorphic facial features. Recently, two unrelated families with the MTOR mutation, c.5395G>A p.(Glu1799Lys), were reported. Here, we describe siblings from a non-consanguineous German family in whom we identified the same heterozygous missense mutation in MTOR. Remarkably, in all reported families with Smith-Kingsmore syndrome and the MTOR c...
