46,XY DSD due to biallelic DHX37 gene mutations

Eltan Mehmet , Helvacioglu Didem , Ates Esra Arslan , Abali Zehra Yavas , Turan Serap , Bereket Abdullah , Guran Tulay

Background: DEAH-box protein DHX37, encodes an RNA helicase, is involved in ribosome biogenesis. Monoallelic mutations in DHX37 gene have recently been identified in 46,XY differences/disorders of sex development (DSD) patients with nonsyndromic gonadal dysgenesis as well as testicular regression, while biallelic mutations have been associated with microcephaly and structural brain abnormalities. Here, we present a patient with penoscrotal hypospadias and bil...

Rahman Syndrome: Hypopituitarism might be responsible for changing height pattern

Betul Kaygusuz Sare , Turan Serap , Esen Nisa , Bereket Abdullah , Yesilyurt Ahmet , Guran Tulay ,

Objective: Histones have important structural and regulatory roles mediating the dynamic packaging of DNA. The dysregulation of histone modification leads to overgrowth syndromes, such as Sotos and Weaver syndrome. Recently heterozygous variants in HIST1H1E, which encodes linker histone H 1.4 has been associated with Rahman Syndrome, which is characterized by a very rare complex phenotype consisting of overgrowth, dysmorphism, and intellectual disabil...

Clinical and molecular genetic characteristics of 98 patients with congenital hypopituitarism: A single-center experience

Yavas Abali Zehra , Arslan Ates Esra , Eltan Mehmet , Turan Serap , Bereket Abdullah , Guran Tulay

Background: Congenital hypopituitarism (CH) refers to a deficiency of one or more pituitary hormones resulting from variants in genes encoding transcription factors for pituitary development. CH cases are mostly sporadic but 5-30% can be familial. Genetic etiology is not determined in most cases. The aim of our study was to evaluate the genetic features of CH using different molecular and/or molecular cytogenetic techniques.Subje...

Single Gene Variations in Etiology in Children with Severe Obesity

Kahveci Ahmet , Kelestemur Elif , Kurt Ilknur , Guran Tulay , Turan Serap , Bereket Abdullah , Haliloglu Belma

Background: Obesity is a multifactorial disease caused by environmental and genetic factors. Single gene defects explain approximately 5-13% of early-onset obesity and these rates vary according to genetic panel used and the rate of consanguinity in the population studied. As the new treatment modalities emerge for monogenic obesity, it is important to identify the molecular etiology of obesity.Materials and Methods: Buc...

Challenges in treating delayed puberty in a girl with Marfan syndrome

Alharbi Mashael , Babiker Amir , Al Zaben1 Abdullah , Al Atawi Mohsen , Al Alwan Ibrahim , Al Dubayee Mohamed

Introduction: Marfan syndrome is an autosomal dominant disorder due to a mutation of the FBN1 gene of chromosome 15 that produces fibrillin, a connective tissue protein. Tall stature can be of a major concern especially in a girl patient. Here we discuss a case of a 13-year-old girl with MFS with tall stature and multiple associated comorbidities that pose challenges in her management for the whole family.Case Report: A ...

The Age of Pubertal Onset Correlates with Pubertal Growth Pattern and Body Weight Change in Girls

Li Yan-Hong , Du Min-Lian , Ma Hua-Mei

Background: Precocious puberty in girls may result in loss of FAH, and particularly may relates to obesity when entering adulthood. However,The influence of the timing of pubertal onset on the FAH and the change of body weight during pubertal stages is still controversial.Objective: The research is to investigate the pubertal growth pattern and the change of BMI levels in girls with ICPP and those who have normal onset of puberty but at different ages.</...

Serum Vaspin Concentration in Full-term, Appropriate-for-Gestational-Age Newborns: Effect of Early-Onset Infections

Stojewska Małgorzata , Wiśniewska-Ulfik Dominika

Objective: Vaspin plays an important role in the foetal and postnatal development of children. The effect of early-onset infection in neonates on vaspin levels is not well known.The aim of the study: 1) evaluation of serum vaspin concentrations in full-term appropriate-for-gestational-age (AGA) newborns, according to their gender, birth asphyxia, type of delivery, occurrence of early-onset infections; 2) analysis of correlations between serum vaspin conc...

Association of Ghrelin Levels and Insulin Resistance in Small for Gestational Age Rats

Liu Wangkai , Shen Zhenyu , Du Minlian , Zhuang Siqi , Ma Huamei

Background: Because ghrelin is closely linked to insulin resistance and type 2 diabetes mellitus in adults, ghrelin might also participate in the development and progression of pathological changes in insulin resistance in SGA infants.Objective and hypotheses: This study aimed to determine insulin sensitivity index (ISI), variation in ghrelin levels, and their relationship in small for gestational age (SGA) rats.Method: The SGA ani...
