Background: Many children with short stature (defined as height SDS <−2S.D.) have no identified cause for their growth impairment and are classified as either small for gestational age or idiopathic short stature depending on birth size. Whole exome sequencing (WES) is a useful tool to identify new genetic diagnoses in this group. Here we describe a recurrent NDUFB3 mutation in children with intra-uterine growth retardation, short stature and ...

Introduction: Children with idiopathic short stature have linear growth impairment despite normal or even high levels of GH. In some of these children IGFI level is low (NGH + Low IGFI (IGFSDS<-1.5). It was observed that some children with GHD (Peak GH < 7 ng/dl after provocation) have normal IGFI levels (GHD +Normal IGFI). The linear growth of these two groups at presentation and their response to GH therapy was not studied well.<p class="abstext"...

Introduction: Data on BP in children with classic congenital adrenal hyperplasia (CAH) is inconsistent.Aim: To assess the trend in BP throughout childhood using data from the International CAH registry and compare this to normative data from the American Academy of Paediatrics (AAP).Method: This retrospective multi-centre study included 37 centres from 20 countries. BP data was ana...

Background: There are inconsistencies in the results reported in a small number of previous studies into growth hormone (GH) treatment of short children with idiopathic short stature (ISS.Patients and Methods: Our study included 20 prepubertal (Tanner 1) or peri-pubertal (Tanner 2) children with short stature (HtSDS < -2) and/or HtSDS > 1SD below their mid parental height SD (MPHtSDS), slow Growth velocity( <...

Aim: Recommendations for replacement glucocorticoids in CAH suggest a dose per body surface area (BSA) of glucocorticoids of 10-15mg/m2/day to maintain a 17-OH Progesterone (17OHP) level of 12-36 nmol/l across all ages. We used longitudinal analysis to assess whether biomarkers and dose of hydrocortisone varied with age in children within the I-CAH registry .Method: This retrospective multi-centre study, inclu...

Introduction: Homozygous loss-of-function mutations of the growth hormone receptor (GHR) gene result in GH insensitivity due to a dysfunctional receptor protein. Heterozygous mutations may result in a variable clinical spectrum ranging from normal height to severe short stature. Gain-of-function variants have been reported rarely.Case Report: We hereby report the case of a Russian boy who was referred to our endocrine o...

Introduction: Children with cerebral palsy (CP) has an increased risk of bone fragility, low areal bone mineral density (aBMD) and low trauma fractures leading to increased pain experience, decreased mobility and lower quality of life.Purpose: The aim of this study was to determine the prevalence of low BMD among children with cerebral palsy in Denmark across the spectrum of gross motor function scale (GMFCS) of I-V and ...

Background: Noonan Syndrome (NS) can overlap clinically and biochemically with growth hormone insensitivity [GHI; short stature (SS), low IGF-I and normal/elevated GH levels]. Mutations in multiple genes regulating RAS/MAPK pathway have been identified in NS including LZTR1 variants. Function of LZTR1 is poorly understood and its role in growth retardation is unknown.Objectives: To functionally characte...

Background: Classic congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency is a rare autosomal recessive condition characterized by cortisol deficiency and elevated ACTH secretion, resulting in excess androgen production. This exposure to excess androgens contributes to advanced skeletal maturation and reduced growth in puberty. Data from the I-CAH registry were analyzed to identify growth-related characteristics of children and adolescents with...

ISS is a condition in which the height is more than 2 SD below the corresponding mean height for age, sex and population, in whom no identifiable disorder is present. Some ISS patients may have varying degrees of IGF-1 deficiency. Recombinant GH treatment has been used by some authors with variable results. Theoretically, low IGF-I level at presentation may affect their response to GH therapy. The question is: do children with ISS and low IGF-I respond differently to GH therap...
