The Natural Mutant Receptor hGRαT556I Causes Primary Generalised Glucocorticoid Resistance Through Decreased Affinity for the Ligand and Impaired Interaction with the GRIP1 Coactivator

Nicolaides Nicolas C , Skyrla Eirini , Vlachakis Dimitrios , Psarra Anna-Maria G , Sertedaki Amalia , Kossida Sophia , Charmandari Evangelia

Background: Primary generalised glucocorticoid resistance (PGGR) is a rare condition characterised by tissue insensitivity to glucocorticoids owing to inactivating mutations of the hGR gene. A new case of PGGR was reported in a patient with an adrenal incidentaloma harboring a novel heterozygous point mutation in the hGR gene, which resulted in threonine (T) to isoleucine (I) substitution at amino acid position 556 of the receptor.Objec...

Introduction: Carney Complex is a rare genetic disorder inherited in an autosomal dominant manner or may occur sporadically due to de novo mutations. It is characterized by the presence of cardiac myxomas, psammomatous melanotic schwannomas, skin pigmentation (blue nevi, lentigines) and multiple endocrine and non- endocrine tumors. It is caused by inactivating mutations or large deletions of the PRKAR1A gene. Management of the syndrome involves ongoing surveil...

Background: Congenital hypogonadotropic hypogonadism (CHH) is caused by impaired function of GnRH neurons, which clinically manifests by incomplete or absent puberty and infertility. The phenotype may be broader with other developmental anomalies such as anosmia, which is known as Kallmann syndrome. To date, there are more than 40 genes in which mutations underlie CHH. Cornelia de Lange Syndrome (CdLS) is characterized by facial dysmorphia, psychomotor delay, ...

Background: Non-idiopathic central precocious puberty (CPP) is caused by acquired or congenital hypothalamic lesions visible on magnetic resonance imaging (MRI), or associated with various complex genetic and/or syndromic disorders without visible lesions on MRI. We investigated the different types and prevalences of non-isolated CPP phenotypes in a large group of consecutive patients with CPP.Methods: This observational cohort study included all patient...

Background: Obesity in childhood and adolescence represents a major health problem of our century that has reached epidemic proportions globally during the last decades. In obese subjects, a relatively high cortisol output in urine has been observed compared to nonobese individuals. However, cortisol concentrations in blood, saliva, and urine in association with obesity have not been consistent across studies. Hair cortisol concentrations (HCC) determined in scalp hair provide...

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...
