Genomic Imprinting Analysis in Clinical Practice

Mackay Deborah

Genomic imprints in humans are epigenetic marks inscribed upon our genomes from the earliest stages of our development, forming a permanent memory of our parental origin. Approximately 1% of human genes are imprinted, with expression that is permanently restricted to either the paternal or the maternal DNA. Genetic or epigenetic errors of imprinting cause a range of imprinting disorders, each with distinctive effects upon growth, development, metabolism and behaviour.<...

Globa Eugenia , Zelinska Nataliya , Temple Karen , Mackay Deborah , Hattersley Andrew , Flanagan Sarah , Ellard Sian

Background: We established a neonatal section of the Ukrainian Pediatric Diabetes Registry (UPDR) to identify cases of neonatal diabetes (ND).Objective and hypotheses: We investigated the genetic etiology and treatment of patients with ND.Method: According to the UPDR the number of children (0–17 y.o) with DM1 in 2015 was 8388 (a prevalence of one in 907), with DM2 – 36 (one in 211519) and with ND – 52 (one in 146436...

Background: Pseudohypoparathyroidism (PHP) is a rare group of disorders characterised by end-organ resistance to parathyroid hormone (PTH), and possibly TSH, with or without features of Albright’s hereditary osteodystrophy.Case presentation: A 14-year-old boy presented with fatigue and spontaneous carpal spasms in association with a febrile viral infection. Past medical history was significant for an episode of asymptomatic hypocalcemia treated with...

Introduction: Neonatal diabetes mellitus (NDM) is a rare (1:300,000–400,000 newborns) but potentially devastating metabolic disorder characterized by hyperglycemia combined with low levels of insulin. Two main groups have been recognized, transient NDM (TNDM) and permanent NDM (PNDM).Objective: To describle clinical features and laboratory manifestations of patient with NDM and evaluate outcome of management.Subject and method...

Transient Neonatal Diabetes Mellitus in Hanoi, Vietnam: Clinical Feature and Outcome

Can Thi Bich Ngoc , Vu Chi Dung , Bui Phuong Thao , Nguyen Ngoc Khanh , Docherty Louise , Edwards Sian , Mackay Deborah , Temple Karen , Ellard Sian

Background: Transient neonatal diabetes mellitus (TNDM) is a rare form of diabetes mellitus that presents within the first 6 months of life with remission in infancy or early childhood. TNDM is mainly caused by anomalies in the imprinted region on chromosome 6q24; however, recently, mutations in the ABCC8 gene, which encodes sulfonylurea receptor 1, have also been implicated in TNDM.Objective and hypotheses: To describe clinical features and lab...

Background: Neonatal diabetes mellitus (NDM), either transient (TNDM) or permanent (PNDM), is a rare form of monogenic diabetes, and usually presents in the first 6 months of life.Objective and Hypotheses: To describe the clinical characteristics and molecular genetics of a large Turkish cohort of NDM from a single centre.Method: NDM patients presenting to Diyarbakır Children State Hospital between 2010 and 2013 were prospecti...

Growth hormone (GH) is commonly used during childhood to treat short stature in Silver-Russell syndrome (SRS), but final height and long-term body mass index (BMI) data are limited.Objective: To evaluate height and BMI in older individuals with molecularly confirmed SRS and compare those previously treated with GH to those untreated.Methods: Growth data on individuals aged ≥13 years with SRS were evaluated from UK, French and...

Beckwith Wiedemann syndrome (BWS) is a rare overgrowth disorder characterised by macroglossia, exomphalos, lateralised overgrowth, organomegaly, hyperinsulinism, and an increased risk of embryonic tumor during early life. In about 80% of BWS cases, molecular defects are identified at the imprinted 11p15.5 region which contains the IGF2 and the CDKN1C genes (most patients show methylation defects at either imprinting control region IC1 or IC2, or paternal unip...
