A novel CEP57 mutation of mosaic variegated aneuploidy syndrome in a Chinese girl: a case report and review of literature

Feng Biyun , Zhang Qianwen , Wang Xiumin ,

Background: Mosaic variegated aneuploidy syndrome(MVA)is a rare genetic disease characterized by mosaic aneuploidies, intrauterine growth restriction, developmental delay, microcephaly, facial dysmorphism, mental retardation, and susceptibility to tumor. It is autosomal recessive and caused by mutations in BUB1B, CEP57, and TRIP13. This study hereby presents a 9-year-old girl with intrauterine growth restriction, short stature, microcephaly, faci...

Sun Manqing , Ma Xiaoyu , Wang Wei , Ni Jihong , Dong Zhiya , Lu Wenli , Xiao Yuan , Wang Defen

We present two cases of a 13-year-old boy and a 12-year-old girl who were initially diagnosed as central diabetes insipidus (CDI). The Magnetic resonance imaging (MRI) showed pituitary stalk thickening with prominent homogeneous contrast enhancement in T1W and the loss of high signal in the posterior pituitary. In addition to CDI, the two children have a common clinical manifestation of growth retardation, with the laboratory tests suggesting complete growth hormone deficiency...

Bone biopsy histomorphometric features of vertebral changes in sickle cell disease.

Sakka Sophia , Nadar Ruchi , Inusa Baba , Cocca Alessandra , Santos Rui , Cheung Moira

Background: Vertebral changes such as biconcave end plate depressions are well described in children with sickle cell disease (SCD). However, as vertebral height reductions are a marker of osteoporosis in children, we aimed to determine whether these could present underlying osteoporosis, by performing transiliac bone biopsies in two patients.Case 1: A 13-year-old female with SCD, presented with back pain. She had delaye...

Use of Zoledronic acid in children with sickle cell disease: a single centre experience

Nadar Ruchi , Santos Rui , Cheung Moira , Cocca Alessandra , Inusa Baba , Sakka Sophia

Children with sickle cell disease (SCD) often suffer from back pain and present with vertebral changes, but the use of bisphosphonates is poorly reported. We present our experience on treating six children with SCD with Zoledronate in a tertiary paediatric endocrinology and haematology centre.Population: Six children with SCD were treated with zoledronate infusions between the years 2016-2021. All children had a history of significant mi...

Is Serum Alkaline Phosphatase Useful in Assessing Rickets Severity on Radiographs in Children with X-Linked Hypophosphataemia on Conventional Therapy?

Uday Suma , Shaw Nick , Mughal Zulf , Randell Tabitha , Högler Wolfgang , Santos Rui , Padidela Raja

Introduction: Conventional treatment of X-linked hypophosphataemic rickets (XLH) involves administration of oral phosphate and vitamin D analogues. An important treatment goal is to heal rickets which is assessed by normalisation of serum alkaline phosphatase (ALP) levels and resolution of radiological signs of rickets.Objectives: To determine the usefulness of serum ALP in assessing disease severity on wrist and knee ra...

Type 1 diabetes in the covid pandemic: what changed?

Diogo Rui , Rua Inês , Cardoso Rita , Dinis Isabel , Mirante Alice , Serra-Caetano Joana

Introduction: The COVID-19 pandemic adversely impacted general access to healthcare. An association between SARS-CoV-2 infection and new-onset type 1 Diabetes (T1D), a more severe disease at diagnosis and a worsening diabetes control have been described.Aim: To evaluate COVID-19 pandemic’s impact in incidence and presentation of T1D on paediatric patients.Material and Methods:</strong...

The Phenotypic Spectrum of Kabuki Syndrome in Patients of Chinese Descent

Wang Yirou , Li Niu , Su Zhe , Xu Yufei , Liu Shijian , Chen Yao , Li Xin , Shen Yiping , Wang Jian , Wang Xiumin , Bodamer Olaf

Background: Kabuki syndrome (KS) is a rare dominant disorder of transcriptional regulation with a complex phenotype including cranio-facial dysmorphism, intellectual disability, developmental delay, hypotonia, failure to thrive, short stature and variable cardiac and renal anomalies. Mutations in either KMT2D or KDM6A cause KS. While the phenotype of KS has been reported in many ethnicities, little is known about the phenotypic spectrum of KS...

Clinical and Molecular Genetic Characterizations of Five Patients Harboring Mutations in the GNAS Gene: A Case Series and Literature Review

Li Xin , Chang Guoying , Wang Yirou , Xu Yufei , Li Guoqiang , Li Xin , Li Juan , Ding Yu , Chen Yao , Wang jian , Wang Xiumin

Objective: Inactivating mutations in the gene encoding the alpha-subunit of Gs (GNAS) gene, which consists of exons 1-13 and encodes the alpha-subunit of the stimulatory G protein (Gsa), are associated with several clinical syndromes, including pseudohypoparathyroidism (PHP), pseudopseudohypoparathyroidism (PPHP), and progressive osseous heteroplasia (POH).Method: We documented patient clinical characteristics a...

A novel mutation of SOX2 gene in an idiopathic hypogonadotropic hypogonadism patient with olfactory bulb agenesis

Tang Yijun , Chen Yao , Feng Biyun , Li Qun , Wang Yirou , Li Xin , Chang Guoying , Li Juan , Ding Yu , Wang Jian , Wang Xiumin

Objective: To enhance the understanding of the clinical phenotypes of patients with SOX2 gene mutations.Method: A retrospectively analysis of the clinical manifestations and the laboratory results of a child diagnosed as idiopathic hypogonadotropic hypogonadism(IHH) by whole exome-gene sequencing and a review of relevant literatures.Results: A 12-year-old boy clinically manifested short stature, mental retardation, a histo...

Insulin Resistance Leads to Mitochondrial Dysfunction in Hepatocyte

Chen Hong , Fang Yanlan , Liang Li , Wang Chunlin

Background: Insulin resistance in obesity and type 2 diabetes is associated with abnormalities in mitochondrial oxidative phosphorylation in skeletal muscle. Whether mitochondrial function changes in hepatocytes with hereditary insulin resistance is not clear. Type A Insulin Resistance Syndrome (TAIRS) is a rare disorder characterized by severe insulin resistance, a condition in which the body's tissues and organs do not respond properly to the hormone ins...
