Early Successful Hematopoietic Cell Transplantation (HSCT) in a Boy with IPEX Syndrome Caused by Novel C.721T>C FOXP3 Mutation

Obermannova Barbora , Formankova Renata , Sumnik Zdenek , Dusatkova Lenka , Pruhova Stepanka , Kayserova Jana , Sedlacek Petr , Lebl Jan

Background: IPEX (OMIM #304790) is a rare and fatal, X-linked immune dysregulatory disorder caused by mutation in transcription factor FOXP3 that result in either quantitative or functional deficiencies of Tregs causing autoimmune disease and allergic inflammation. HSCT is the only curative therapy available for IPEX patients.Objective: Presented boy was born at 38th GW with birth weight 3380 g and birth length 50 cm. Three maternal brothers d...

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...

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...

Chondrocyte regulating and other growth plate genes are invaluable growth regulators: a study on children with short stature from 55 consanguineous families

Anne Amaratunga Shenali , Tayeb Tara Hussein , Dusatkova Petra , Elbova Lenka , Pruhova Stepanka , Lebl Jan ,

Introduction: Statural growth is regulated by multiple genetic, epigenetic and environmental mechanisms. The GH-IGF-1 axis was long believed to be the main linear growth regulator in children until more recent studies showed that the complex regulation of growth plate chondrocytes play an equal role. In order to extend our knowledge about the genes involved in short stature, we studied a unique cohort of children with short stature from consanguineous families...

Clinical and genetic characteristics of patients suspected to have Maturity-Onset Diabetes of the Young in the Czech Republic

Dusatkova Petra , Vesela Klara , Kolarova Katerina , Sumnik Zdenek , Lebl Jan , Pruhova Stepanka

Introduction: Maturity-Onset Diabetes of the Young (MODY) represents the most frequent form of monogenic diabetes. Genetic testing of Czech patients with clinical suspicion on MODY began 22 years ago. Aim of the study was to describe the prevalence of MODY subtypes among referred probands with diabetes and to define their clinical characteristics and possible differences.Methods: Clinical criteria for genetic testing of ...
