Background: The adenylate cyclase 3 (ADCY3) gene encodes a membrane-associated protein involved in the formation of cyclic adenosine monophosphate (cAMP) from adenosine triphosphate (ATP). This gene seems to be is involved in the regulation of several metabolic processes and has been recently associated to pathophysiological metabolic conditions. Several ADCY3 variants have been linked with obesity in children.M...

Background: Resistance to thyroid hormone (RTH) is a dominantly inherited rare disorder (1:40000) mainly due to mutations in the THRB gene that lead to a decreased end-organ responsiveness to thyroid hormone. Clinical and molecular characteristics of four patients with RTH are described.Patients and methods: Four patients from three non-related families were studied; two boys (8.3 and 9.2 years old) and 2 adults (35 year old male and 27 year old...

Background: Central precocious puberty (CPP) due to premature activation of GnRH secretion results in early epiphyseal fusion and to a significant compromise in the achieved final adult height as well as psychological consequences. So far only a limited number of genetic determinants have been associated with the pathogenesis in children with CPP. In this original research, rare sequence variants in MKRN3, DLK1, KISS1, and KISS1R genes were i...

Abstract: Objective: Congenital hypogonadotropic hypogonadism (CHH) is a rare genetic disease caused by GnRH deficiency and characterized by absent or incomplete puberty with infertility. The identification of the genetic cause in this group of patients through the use of next generation sequencing (NGS) can assist to the clinical management.Methods: Seven GnRH deficient nonrelated Cypriot probands were ...

Purpose: Multiple Endocrine Neoplasia type 2 (MEN2) affects patients with RET proto-oncogene mutations. This cohort study refer to patients who were diagnosed with familial medullary thyroid carcinoma (MTC) and underwent RET genetic testing in Cyprus between years 2002 and 2017.Methods and Patients: Forty patients underwent RET testing by Sanger sequencing of exons 10–11 and 13–16. Genotyping with STR genetic markers ...

Background: Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21-OHD) is worldwide the most common autosomal recessive disorder caused by defects in the CYP21A2 gene.Objective: The main objective of the study was to evaluate CAH in Cyprus over a 10 year period.Methods: All known patients were included in a population retrospective subset analysis of Cypriot patients with confirmed CAH and their clinica...
