A girl with Trisomy 21 presents with Van Wyk-Grumbach syndrome. A rare diagnosis

Dikaiakou Eirini , Vlachopapadopoulou Elpis Athina , Kosteria Ioanna , Panos Alexandros , Dede Eirini , Koutrouveli Eleni , Zouridaki Christina , Michalacos Stefanos

Background: Van Wyk-Grumbach syndrome (VWGS) is a rare diagnosis that should be suspected in children with signs of peripheral precocious puberty and hypothyroidism. It is characterized by multicystic enlarged ovaries, in the presence of long-term severe hypothyroidism. Treatment of VWGS consists of hormonal replacement with levothyroxine. Usually, ovarian cysts and increased ovarian volume subside within an average of 2 months but can persist up to 12 months after treatment.<...

Single nucleotide polymorphisms (SNPs) of the LIN28B gene and age at menarche in a sample of Greek girls

Tsinopoulou Vasiliki-Rengina , P. Kotanidou Eleni , Bacopoulou Flora , Fidani Liana , Gerou Spyridon , Galli-Tsinopoulou Assimina , Christoforidis Athanasios

Objectives: Menarche is defined as the first menstrual bleeding in females, and the age of onset varies and depends on a complex interaction between genetic and environmental factors. The LIN28B gene single nucleotide polymorphisms (SNPs) rs314276, rs7759938 and rs314280 appear to be associated with cases of premature and early menarche. International databases report that the presence of a G allele of rs314280SNP shifts menarche 1.2 months earlier, a C allele...

Introduction: Insulin (INS) gene is reported to be the most important gene involved in Type 1 Diabetes (T1D); its expression is inversely correlated with methylation at CpG sites. Hypermethylated primers are associated with decreased expression.Aim: The present study aims to investigate possible differences in DNA methylation pattern between T1D youngsters and healthy controls.Patients and Methods: Twenty T1D parti...

Introduction: HLA-G gene is involved in the control of immune response. It plays a primary role on immune tolerance and may participate in controlling autoimmune responses serving as a potential independent susceptibility marker. HLA-G has been isolated in some secretory granules and on the cell surface of primary islet cells induced to secrete insulin. Subsequently, it could be hypothesized that HLA-G methylation at pancreatic islet could sustain T cell activation and onset o...

Lessons from Wolfram Syndrome: Initiation of DDAVP Therapy Causes Renal Salt Wasting due to Elevated ANP Levels, Rescued by Fludrocortisone Treatment

Background-Hypothesis: Sudden initiation of treatment for diabetes insipidus (DI) with DDAVP causes abrupt volume expansion resulting in particularly high secretion of Atrial Natriuteric Peptide (ANP) (1). ANP blocks all stimulators of zona glomerulosa steroidogenesis, resulting in secondary mineralocorticoid deficiency and acute hyponatremia, causing renal salt wasting (RSW) (2). Cases: Two sisters, a 19-year-old girl (A) and a 7-year-old girl (B) with Wolfra...

Background: Protein subfamilies within the Nuclear receptor (NR) family share common domain architecture. These closely related receptors and their cognate ligand compounds play a key role in homeostasis, reproduction, growth, and development. Despite their biological significance, their evolution and diversification remains to be elucidated. SNPs and mutations are characterized by the permanent alteration of the nucleotide sequence in the genome of an organism. These alterati...
