Background: Congenital isolated ACTH deficiency (IAD) is a rare inherited disorder that is clinically and genetically heterogeneous. Patients are characterized by low or absent cortisol production secondary to low plasma ACTH despite normal secretion of other pituitary hormones and the absence of structural pituitary defects. Mutations in the TBX19 gene, a T-box factor selectively expressed in developing corticotroph cells, have been identified so far only in cases of neonatal...

Introduction: Congenital central hypothyroidism is a rare pathology, whose molecular origin has been identified more frequently since discovery of the role of IGSF1. The natural evolution of central hypothyroidism in patients with mutations is not well known however.Case report: A male infant born at term with a normal birth weight received thyroid function tests in the neonatal period because of symptoms of bra...

Background: Congenital isolated adrenocorticotrophic hormone (ACTH) deficiency (IAD) is a rare condition. It is characterized by low plasma and cortisol levels and preservation of all other pituitary hormones (2 cases described with transient partial growth hormone deficiency). The principal molecular cause is identified as TPIT mutation. We present here the case of a neonate with TPIT mutation and ACTH deficiency associated with probable growth hormone and thyrotropin deficie...

Poirier-Bienvenue syndrome (POBINDS) is rare neurodevelopmental syndrome, resulting from germline hereteozygous CSNKB2 pathogenic variants. Patients mainly presented with severe epilepsy, delayed psychomotor development and/or profound intellectual disability. More recently patients with CSNK2B pathogenic variants and mild intellectual disability (ID), without any history of epileptic symptoms were reported. Short stature is present in 66% of patients, due in...

Background: G, male, was born at 39 GW by emergency CS from non-consanguineous parents. Prenatal US showed growth at lower limits of normal from 22 GW, short limbs and polyhydramnios. Amniocentesis karyotype was 46,XY. At birth weight and length were <3rd percentile, head circumference was between 10 and 25th percentile. At physical examination: short limbs, short neck, cryptorchidism, and microphallus. Early the baby presented mild respiratory distress and a severe episod...

Background: Congenital hypopituitarism is a rare disease. Although our understanding of the involved transcription factors is improving, mutations in candidate genes are rarely identified. Extra-pituitary symptoms can point towards new genes of interest. FOXL2 is mutated in blepharophimosis/ptosis/epicanthus inversus syndrome (BPES), a rare affection that combines congenital alterations of eyelids with ovarian dysgenesis in some families. Moreover, we have previously reported ...
