GLI2 is a downstream transcription factor in Sonic Hedgehog signaling, acting early in ventral forebrain and pituitary development. Heterozygous GLI2 mutations have been reported in patients with isolated or combined pituitary hormone deficiency (CPHD).Objective: Study of genetic etiology of the hypopituitarism and identification of the genetic alteration in GLI2 gene.Methodology: Molecular study: Search for varia...

Background: Acromesomelic dysplasia Maroteaux type (AMDM) (OMIM 602875) is a rare autosomal recessive skeletal disorder with an approximate prevalence of 1/1,000,000) and characterized by severe dwarfism accompanied by shortness of distal and middle segments of extremities. Mutations in the NPR2 gene which encodes for the natriuretic peptide receptor B (NPR-B) is the underlying genetic cause of this disorder.Objective and hypotheses: Genetic con...

Background: The beginning and evolution of physiological puberty may be occurring earlier, resulting in change in the age at which clinical investigation on precocious puberty must be conducted, as well as concerns regarding the possible deleterious effects of hormone exposure in a later stage of life.Objective and hypotheses: Assess age of beginning and evolution of puberty in boys and girls acknowledging the age of thelarche (T), menarche (M), period b...
