Background: Primary ovarian insufficiency (POI) affects 1% of women and is associated with significant medical consequences. In approximately 10% of cases, POI presents early with absent puberty or primary amenorrhoea. A genetic cause for POI can be found in up to 30% of women. Identified genes often relate to the complex biological processes occurring in fetal life which underpin normal ovary development and function in later adulthood.Objective: We aim...

A case report of Non-syndromic 46, XX testicular DSD presenting as a genital ambiguity - Clinical, molecular and cytogenetic analysis

Behera Kishore , behera Smruti , Sahoo Subrat

Background: To demonstrate the etiology of 46, XX sex reversal by investigating the clinical feature and its relationships with chromosomal karyotype and the SRY (sex-determining region Y) gene.Methods: A child with genital ambiguity with hypospadias and bifid scrotum consulted to our endocrine OPD for further management. Clinical data was noted, and Karyotype analysis of G-banding in lymphocytes and Fluorescence in situ hybridization (FISH) wer...

Zhang Jun , Liu Yingyan , Yang Ningjing , Chen Qiuli , Guo Song ,

Objective: To recognize Schimke immune-osseous dysplasia from a case of spinal epiphyseal dysplasia.Method: Summarize the characteristics of one case of Schimke immune-ossesous dysplasia, and increase awareness of this disease.Result: The patient, male, with non-consanguineous parents, was born on May 8, 2012. He was hospitalized in our hospital in January 2020 due to his short stature for more tha...

The utility of continuous glucose monitoring systems in the management of children with persistent hypoglycaemia

Vijayanand Sathyakala , Stevenson Paul G , Grant Maree , Choong Catherine S , Davis Elizabeth A , Abraham Mary B ,

Background: Glucose monitoring is vital in children with persistent hypoglycaemia to reduce the risk of adverse neuro-behavioural outcomes1. Continuous glucose monitoring (CGM) systems provide real-time glucose levels however; information on its usefulness in monitoring glucose levels in this cohort is limited2, 3.Objective: To ascertain the effectiveness of CGM and to evaluate parentsÂ’ experie...

Background: Type 1 diabetes (T1D) is characterized by chronic hyperglycemia and microvascular complications like retinopathy, nephropathy, and neuropathy in long term. Nailfold video capillaroscopy (NVC) is a non-invasive method used to examine the microcirculation in the skin. In this study, we aimed to evaluate the microvascular structure in T1D with NVC, observe capillaroscopic alterations, and reveal the relationship of capillaroscopic abnormalities with g...

Methylome analysis in idiopathic central precocious puberty girls

Palumbo Stefania , Giurato Giorgio , Cirillo Grazia , Miraglia del Giudice Emanuele , Palumbo Domenico , Grandone Anna

Background: Although the transition from the pre-pubertal condition to puberty occurs physiologically within a bounded age range, recent data indicate a central role for epigenetics in the regulation of several genes that could mediate an alteration of pubertal onset. Moreover, changes occurring during this developmental stage have often been associated with susceptibility to a wide range of diseases in later life. To identify changes in DNA methylation profil...

Variants in Methyl-CpG-binding protein 2 (MECP2) are associated with X-Linked Central Precocious Puberty

E Read Jordan , Guasti Leonardo , Paganoni Alyssa , Korbonits Marta , R Howard Sasha

Whilst several key genetic contributors to the phenotype of central precocious puberty (CPP) have been recognized, many familial cases remain without clear a genetic aetiology. Causal genetic variants are reported in imprinted genes Makorin ring finger protein 3 (MKRN3) and Delta-like homolog 1 (DLK1), alongside Kisspeptin-1 (KISS1) and (KISSR1), implicating mis-regulation of transcriptional control of the kisspeptin and GnRH neuroendocrine systems in onset of CPP. We recently...

Celiac disease in a patient with Sclerosteosis: an association or just a co-incidence?

Abdelmeguid Yasmine , Riad Salma , Mokhtar Nada , Taha El-Hendawy Mahmoud

Sclerosteosis is a rare autosomal recessive disorder characterized by progressive skeletal overgrowth and increased bone density. Loss of function mutations of SOST gene, coding for sclerostin, are linked to sclerosteosis. Sclerostin plays a critical role inhibiting osteoblastic activity and preventing excessive bone formation by antagonizing the Wnt signaling pathway. Sclerosteosis patients are often tall and have excessive body weight due to high skeletal weight. To...

The pattern of growth in a girl with short stature and duplication at 5q35.2q35.3 encompassing NSD1

Banaszak-Ziemska Magdalena , Niedziela Marek

Introduction: Characteristic features in patients with a duplication at 5q35.2q35.3 encompassing NSD1 are short stature, microcephaly, mild developmental delay, behavioural problems, digital anomalies and defects of internal organs. The above-mentioned features are reversed to Sotos syndrome phenotype, which is associated with a microdeletion in the same chromosomal region. In the literature, 41 patients were reported so far.Case...

A variant of uncertain significance in HMGA2 gene, in a 2-year-old child with Silver Russel syndrome like phenotype - a case report

Bourousis Evangelos , Xatzipsalti Maria , Lazaros Leandros , Nitsos Nikolaos , Stamogiannou Lela

Introduction: Silver-Russell syndrome 5 (SRS5) is characterized by asymmetric intrauterine growth restriction (IUGR), poor postnatal growth, macrocephaly at birth and feeding difficulties.
