Abstract
Purpose
Suppressor of cytokine signaling 2 (SOCS2) is a STAT5b-regulated gene and one of its functions is to influence growth and development through negative regulatory effects on GH/IGF-1 pathway. So, we evaluate the potential influence of SOCS2 single nucleotide polymorphisms (SNPs) on clinical and laboratorial characteristics of a large cohort of Brazilian patients with acromegaly.
Methods
Four SOCS2 SNPs (rs3782415, rs3816997, rs3825199 and rs11107116) were selected and genotyped by real-time PCR using specific Taqman probe assays. A total of 186 patients (116 women, age range 26–88 years) were evaluated.
Results
No association of SOCS2 genotypes was observed with none of the following clinical and laboratorial characteristics: age, sex, body mass index, comorbidities, basal GH, oral glucose tolerance test GH nadir, IGF-I, ULNR-IGF-I.
Conclusion
Despite of the key role of SOCS2 in the regulation of GH receptor signaling, we did not find any significant association between SOCS2 polymorphisms and acromegaly.
