Background: GNAS 1 gene (guanine nucleotide binding protein, alpha stimulating) encodes the alpha subunit of the stimulatory guanine nucleotide-binding protein (G-protein). Variations in the GNAS 1 can cause several disorders including Pseudohypoparathyroisism Type 1A (PHP1A), Type 1B (PHP1B), Type 1C (PPHP1C), Progressive Osseous Heteroplasia (POH), Pseudopseudohypoparathyroidism (PPHP) and McCune-Albright syndrome (MAS).Objectives: To report 2 patients...

Background: Molecular defects are rarely detected in Premature ovarian insufficiency (POI) patients.Objective and Hypotheses: We hypothesized that the frequency of causative molecular defects could be higher in cases with early onset of POI. Moreover, the analysis of multiple genes in the same POI group could disclose co-existence of more than one molecular aberration.Method: In 25 subjects, aged 17.1±7 years at POI onset, bid...
