Novel genetic cause of idiopathic short stature

Abstract: Traditionally, the growth hormone – insulin-like growth factor I (GH – IGF-I) axis is the most important signaling pathway in linear growth, and defects in this axis present as growth hormone deficiencies or IGF-I deficiencies. However, subtle changes in serum levels of GH or IGF-I, caused by gene mutations involved in the GH – IGF-I axis, can present as idiopathic short stature (ISS). This paper briefly discusses GHR and IGFALS. In addition, recent studies have shown that many factors, including paracrine sig… Show more

“…. Mutations and deletions in SHOX can lead to Leri‐Weill dyschondrosteosis and idiopathic short statue (Kang, ; Oliveira & Alves, ). Although clinical significance of this microduplication has not been clarified, three cases of short statue with SHOX duplication have been reported (Benito‐Sanz et al, ).…”

“…In recent years, various attempts have been made to shed light on the aetiology of ISS. Some genome-wide association studies (GWASs) have shown that multiple genes determine height variation within a population (Wit 2011, Wit & Oostdijk 2015, Kang 2017. A more recent study speculates on the prevalence of one gene over the others to determine one's height (Pennisi 2018).…”

“…(2,5%), gene associado à baixa estatura proporcional sem anormalidades esquelética quando no estado dominante (78,79,94) . O que foi compatível com a clínica dos pacientes e com estudos que identificaram entre 1,9% e 12,7% de variantes neste gene associados à baixa estatura idiopática (86,94,95) . Variantes em heterozigose no SHOX explicam de 2% a 15% dos casos de baixa estatura idiopática de acordo com estudos na literatura (26,86,87,96) , podendo incluir pacientes nascidos pequenos para idade gestacional.…”

Variantes em heterozigose no SHOX explicam de 2% a 15% dos casos de baixa estatura idiopática de acordo com estudos na literatura (26,86,87,96) , podendo incluir pacientes nascidos pequenos para idade gestacional. Estes achados demonstram uma tendência observada na literatura recente de identificar defeitos em genes envolvidos no desenvolvimento da cartilagem de crescimento que causam quadros inespecíficos de baixa estatura sem caracterizar uma displasia esquelética típica (47,94,97,98) .…”
