Background: SGA-SS, defined as birth weight and/or birth length below -2SD for gestational age and postnatal statural height below -2.5SD according to age- and sex-specific standards, is a heterogeneous condition reflexing exogenous (maternal, placental) or endogenous (foetal) inadequacies. Within the past two decades, a handful of genetic causes of SGA-SS have been elucidated. However, how each genetic aetiology impacts individual GH treatment outcomes awaits...

Background: SGA-SS is a heterogeneous condition defined as birth weight and/or birth length below -2SD for gestational age and postnatal height below -2.5SD, according to age-and sex-specific normative values. Despite being an indication for growth hormone (GH) therapy for 15 years, aetiology and prediction of treatment outcomes in most of SGA-SS children awaits elucidation.Aim: To decipher genetic aetiologies among a la...

Hutchinson-Gilford Progeria Syndrome (HGPS) is an extremely rare condition (estimated incidence 1:4–8 million), caused by mutations in LMNA gene, which leads to premature aging. Median life expectancy is shortened to 13 years due to vascular complications such as stroke or myocardial infarction. We present below the history of a child born with a pathogenic LMNA variant c.433G>A (p.Glu145Lys). A male patient was referred due to failure to thrive and low growth velocit...

Background: Approximately 10% of children born small for gestational age (SGA) fail to catch-up nd remain short (SGA-SS). Although several mechanisms causing SGA-SS have been elucidated, the primary cause remains speculative in most cases.Aim: To decipher genetic causes of SGA-SS defined as birth length and/or birth weight <-2 SD for gestational age, and body height <-2.5 SD after the 3rd year of life within a larg...

Background: Ten percent of children born small for gestational age fail to catch-up and remain short during childhood (SGA-SS). Several genes causing SGA-SS have been described, however, in most cases, the mechanisms of prenatal and postnatal growth impairment remain unknown.Aim: To decipher genetic etiologies within a large single-center cohort of SGA-SS children in order to better understand the pathophysiological mech...
