Background: —Floating-Harbor syndrome(FHS) is a rare autosomal dominant genetic disorder associated with heterozygous mutations in SRCAP gene. The SRCAP protein activates the cAMP-response element binding protein-binding protein(CREBBP) gene that is involved in the regulation of cell growth and division.Objective: To report on long-term follow-up data of a boy with FHSMethods:...

We analyzed the clinical data and the growth parameters of 50 newborns and young infants (age: 1.6 ± 0.9 months) admitted to our hospital (Al Wakhra Hospital, Department of Pediatrics, Doha, Qatar), between 1-1-2016 to 1-1-2017, with acute meningitis. Anthropometric measurements included weight, length, and head circumference. Length SDS (L-SDS) and body-mass-index (BMI) were calculated and recorded at every clinic visit, every 3 months for 8 ± 2 months.<p class=...

There is an intriguing association between DS and thyroid abnormalities, which include sub-clinical, overt hypothyroidism, hyperthyroidism, and positive thyroid Antibodies. The prevalence of these abnormalities varies considerably depending on the diagnostic criteria and the selected population which includes sample size and age group.Aim: To measure the prevalence of thyroid dysfunction and associated autoimmunity in children with Down ...

Wolf-Hirschhorn syndrome is a genomic disorder caused by 4p16.3 deletion with facial dysmorphology, growth retardation, developmental/intellectual delay and seizures. After 165 kb critical region encompassing NSD2 was identified, most recently, three NSD2 loss of function variants was uncovered in patients with overlapping phenotype with Wolf-Hirschhorn syndrome. In our study, a NSD2 variant, c.1577dupG (p.Asn527fs*14) was identified in two patie...

Say-Barber-Biesecker-Young-Simpson syndrome (SBBYSS) is a rare and clinical well-described disease caused by de novo heterozygous mutations in KAT6B gene. Genitopatellar syndrome (GS) is also caused by the mutations of gene KAT6B and shares some common clinical symptoms with SBBYSS. The phenotypic spectrum caused by KAT6B is very broad that some patients cannot be classified as SBBYSS or GS. Herein, we report one de novo heterozygous KAT6B truncating variants c.5124delC (p.L17...

Introduction Objective: The SHOX gene is located in pseudoautosomal region of chromosomes of Xp22.33 and Yp11.32. It plays role in proliferation and differentiation of epiphyseal chondrocyte. Leri-Weill syndrome is observed with loss of an allele, while missense mutations lead to idiopathic short stature without any dysmorphic findings. This report presents clinical features of three cases diagnosed with Leri-Weill syndrome, and their responses to rhGH treatme...

Background: Down syndrome (DS) is associated with thyroid dysfunction including both congenital and acquired hypothyroidism (HT) However, data about thyroid function in infants < 1 year with DS is scarce.The aim of this study was to investigate the prevalence of different thyroid dysfunctions in a cohort of infants with DS (n = 47) (22 M, 25 F) and follow up their linear growth and weight gain for an average of 4 years.<p cla...

Background: Subclinical hypothyroidism is the most common in DS. Thyroxin administration to improve growth early in life is still controversial.We measured linear growth (BMI, height SDS (HtSDS) and weight gain/day ) in 3 groups of infants and young children with Down syndrome (trisomy 21) and divided them retrospectively into 3 groups according to their thyroid function. Group 1 (n = 25) with normal FT4 and TSH, group 2 (n = 20)...

Anthropometric somatotype components show significant resemblance in monozygotic (MZ) and dizygotic twins (DZ) twins within each sex with a greater resemblance within MZ twin pairs than within DZ twin pairs. In many studies a significant positive correlation was found between the parental height and the height of girls with TS.This girl with Turner syndrome {46, X, i(Xq) presented at the age of 7.5 years for evaluation of her short stature. Her clinical ...

Background: Pallister-Hall syndrome (PHS) is a rare autosomal dominant disorder characterized by a complex of different abnormalities (polydactyly, bifid epiglottis, hypothalamic hamartoma, imperforate anus).

PHS is associated with hypopituitarism, early or precocious puberty.Objective: to demonstrate a patient with PHS treated with growth hormone (GH) and gonadotropin re...

Introduction: Bloom syndrome (BS) is a rareautosomal recessive disorder caused by mutations in the BLM gene, located on the long arm of the chromosome 15 (15q26.1). The typical symptoms of the disease are short stature, low birth weight, dysmorphic features including long, narrow face (dolichocephaly), micrognathism and prominent nose and ears. Other characteristic features include a rash following sun exposure, hyper-pigmented areas or cafe-au-lait s...

Background: Chronic granulomatous disease (CGD) is a rare primary immunodeficiency. Growth retardation is a common finding, due to recurrent severe infections and inflammatory complications. Bone marrow transplantation (BMT) can lead to stable remission, with overall pediatric survival rates > 90% after non-myeloablative conditioning transplants. As reported in previous studies, growth rates in CGD recovered following BMT.<strong...

Small for gestational age (SGA) is an important cause of short stature in developing countries like India.Results: 97 children between 2-4 yrs of age who were born SGA were studied over six months and those whose height was below the third percentile on WHO growth charts were classified as short.The inter-group statistical comparison of distribution of categorical variables were tested using Chi-Square test and int...

Turner syndrome is the most common chromosomal disorder in girls. They present classically short stature and delayed puberty. Turner girls with 45,X karyotype show normal female external genitalia. But Turner patients containing 45,X/46,XY mosaicism, or Sex-determining Region Y(SRY) gene may have mixed gonadal dysgenesis with various external sexual differentiation or pure gonadal dysgenesis. Existence of Y chromosome particles in Turner syndrome implies that they have risk of...

Background: Wiedemann–Steiner syndrome (WSS) is a rare autosomal dominant disorder characterized with hypertrichosis cubiti, dysmorphic facial appearance (hypertelorism, thick eyebrows, and narrow palpebral fissures), psychomotor delay, and short stature. WSS is caused by a mutation in the KMT2A gene. The timing of secondary sexual characteristics in patients with WSS is not well known. To our knowledge, two patients (one boy and one girl) with W...

Backgrounds: There is a no reliable population-based prevalence data of Down's syndrome (DS) in South Korea. In the present study, we try to estimate the incidence and prevalence of DS and cardiac complications in South Korea using data of National Health Insurance Service (NHIS) data and Rare Diseases Registry.Methods: We collected the data on DS patients who registered in the Rare Diseases Registry (RDR) between 20...

McCune-Albright syndrome consists of pigmented skin patches, polyostotic fibrous dysplasia, and a variety of endocrine disorders. Café au lait spots are characteristic skin lesions that reflect the onset of the somatic mutations in melanocytes during embryonic development. Polyostotic fibrous dysplasia is caused by activation of the parathyroid hormone receptor pathway in bone. Hormonal hypersecretion is the result of constitutive cyclic AMP production caused by ...

Context: Most children with Prader-Willi syndrome (PWS) develop scoliosis. Scoliosis has a prevalence of 80% in children with PWS older than 10 years, who were not treated with growth hormone (GH). GH is an approved treatment for children with PWS and improves psychomotor development and body composition. The onset and progression of scoliosis are generally associated with an accelerated growth velocity and GH treatment might cause accelerated growth. Sinc...
