Growth Characteristics of a Girl with Multicentric Carpo-Tarsal Osteolysis Caused by Novel Mutation in the MAFB Gene

Dusatkova Lenka , Potuznikova Kristyna , Zemkova Daniela , Marik Ivo , Rozenkova Klara , Lebl Jan , Pruhova Stepanka , Sumnik Zdenek

Background: Recently, mutations in the highly conserved transactivation domain of MAFB gene have been identified as a cause of multicentric carpo-tarsal osteolysis (MCTO), rare skeletal disorder characterised by extensive bone resorption predominantly of the carpal and tarsal bones and frequently accompanied by progressive renal impairment. The MAFB is a basic leucine zipper transcription factor that is involved in the regulation of osteoclastogenesis and renal develo...

Phenotypic Variability of Identical Mutations in the ABCC8 Gene in Two Families

Rozenkova Klara , Zapletalova Jirina , Dusatkova Lenka , Dusatkova Petra , Obermannova Barbora , Pruhova Stepanka , Lebl Jan , Sumnik Zdenek

Background: Mutations in the SUR1 subunit of the KATP channel encoded by the ABCC8 gene can result in diverse phenotypes ranging from Transient Neonatal Diabetes (TNDM) to type 2 diabetes in adulthood. These patients may benefit from sulphonylurea treatment.Objective and hypotheses: To describe the course of diabetes in two families with ABCC8 gene mutations and to assess the effect of sulphonylurea treatment.<p class="ab...

Design and Clinical Development of TransCon Growth Hormone for Growth Hormone Deficiency (GHD)

Beckert Michael , Gilfoyle David , Mikkelsen Jan Moller , Rasmussen Grethe , Rau Harald , Sprogoe Kennett

Background: TransCon GH is designed as a once-weekly sustained-release prodrug of recombinant human GH (hGH, somatropin). Based on the inert TransCon prodrug technology unmodified native hGH is released with a Cmax and AUC comparable to daily therapy. TransCon GH leverages the known pharmacology of daily hGH and is being developed for the treatment of GH deficiency (GHD) in children and adults.Objective and hypotheses: Develop a safe and efficacious sust...

Thyroid Cancer is the Most Frequent Secondary Solid Tumour Following Allogeneic Stem Cell Transplantation in Childhood – A Single Centre Experience

Snajderova Marta , Keslova Petra , Sedlacek Petr , Formankova Renata , Riha Petr , Stary Jan

Backgroud: Allogeneic haematopoietic stem cell transplantation (HSCT) is a potentially curative therapy for a variety of malignant and non-malignant disorders. With improved outcomes, increasing attention has been drawn to late complications in long-term survivors. Secondary cancer belongs to the most serious complications.Objective: Occurrence of secondary solid tumours at HSCT Unit, University Hospital Prague- Motol was analysed....

Papillary Thyroid Cancer After Hematopoietic Stem Cell Transplantation in Young Age

Snajderova Marta , Keslova Petra , Sykorova Pavla , Sedlacek Petr , Formankova Renata , Stary Jan

Background: Increasing number of survivors following hematopoietic stem cell transplantation (HSCT) leads to necessity to focus also on careful monitoring for late effects. High dose chemotherapy and total body irradiation (TBI) is used for conditioning regimen in many patients. Thyreopathies belong to the most frequent among late endocrinopathies.Objective: Aim of the study was to evaluate incidence of secondary thyroid malignancies after HSCT in young ...

Transient Hyperglycaemia Preceded by Neonatal Hyperinsulinaemic Hypoglycaemia in an Infant with a Novel HNF1A Mutation

Obermannova Barbora , Rozenkova Klara , Dusatkova Petra , Pruhova Stepanka , Sumnik Zdenek , Lebl Jan

Background: The phenotype associated with heterozygous HNF1A gene mutations has recently been extended to include neonatal hyperinsulinaemic hypoglycaemia (HH) in addition to maturity-onset diabetes of the young (HNF1A–MODY).Objective and hypotheses: The baby boy was born at 38th week of gestation; BW 4110 g; BL 53 cm (LGA). The mother had gestational diabetes; her father is treated for diabetes mellitus from the age of 50 years. The boy de...

Girls with Turner Syndrome have Normal Muscle Force but Decreased Muscle Power

Soucek Ondrej , Lebl Jan , Matyskova Jana , Snajderova Marta , Kolouskova Stanislava , Pruhova Stepanka , Hlavka Zdenek , Sumnik Zdenek

Background: Turner syndrome (TS) associates with decreased bone mineral density and altered bone geometry, a risk factors leading to increased fracture rate. Although hypogonadism or SHOX gene haploinsufficiency are the probable causes, the exact mechanism remains unclarified. Particularly, the muscle function as an important determinant of bone strength has yet not been widely studied in TS patients.Objective and hypotheses: We hypothesised there is mus...

Anophthalmia, Abnormal Pituitary Development, and Suboptimal Response to GH Therapy in Two Children With Microdeletions of 14q22q23

Dusatkova Petra , Slamova Zuzana , Sumnik Zdenek , Simandlova Martina , Zemankova Elsa , Sedlacek Zdenek , Lebl Jan

Background: Microdeletions of 14q22q23 have been associated with eye abnormalities. Other symptoms in deletion carriers are less well recognized.Objective and hypotheses: We focused on growth characteristics and response to GH treatment in two unrelated children with 14q22q23 deletions.Method: Array comparative genomic hybridisation (aCGH).Results: Both patients displayed bilateral anophthalmia. Their brain M...

Gain of Function STAT3 Mutation in a Boy with Early Onset Autoimmune Diabetes and Thyroid Disease, Prenatal and Postnatal Growth Impairment and Lymphoproliferation

Sediva Hana , Dusatkova Petra , Dusatkova Lenka , Sumnik Zdenek , Kolouskova Stanislava , Pruhova Stepanka , Lebl Jan

Background: Recently, a new monogenic cause of multiple immune system disorders and short stature has been attributed to germline activating mutations in the STAT3 gene encoding signal transducer and activator of transcription 3. Possible pathophysiological mechanisms include enhanced proliferation and activation of T-helper 17 cells and inhibition of regulatory T-cells by STAT3, as described in in vitro studies.Case presentation: The a...

Multiple Malformations Extending the Phenotypic Spectrum of Antley–Bixler Syndrome in a Patient with P450 Oxidoreductase Deficiency due to Two Novel Mutations of the POR Gene

Janchevska Aleksandra , Idkowiak Jan , Caredda Elisabeta , Hurst Jane , Dattani Mehul T , Arlt Wiebke , Spoudeas Helen A

Background: P450 oxidoreductase deficiency (PORD) is characterised by glucocorticoid and sex steroid deficiency and skeletal malformations, resembling Antley–Bixler syndrome (ABS, MIM 124015), a skeletal malformaton phenotype also present in patients with fibroblast growth factor receptor 2 mutations (FGFR2, MIM 176943). While genetic testing confirms both conditions, establishing the exact diagnosis on clinical grounds can be challenging.Objective ...
