What is the Meaning of SHBG Gene?

The SHBG Gene, officially known as SHBG, provides the genetic instructions for producing Sex Hormone-Binding Globulin, a critical glycoprotein responsible for binding and transporting sex steroids like testosterone and estradiol in the circulation. Variations in this gene can alter SHBG levels, thereby directly affecting the bioavailability of these hormones to target tissues, which is clinically significant for assessing androgenic status. Precise SHBG quantification is essential for interpreting total hormone assays.

What is the Origin of SHBG Gene?

The gene name reflects its product, SHBG, which itself is named for its primary function: binding sex hormones in the blood globulin fraction. Its discovery was tied to understanding the regulation of sex steroid action.

What is the Mechanism of SHBG Gene?

The SHBG protein, synthesized primarily in the liver under transcriptional control from its gene, binds circulating testosterone and estradiol with high affinity, sequestering them into a non-bioavailable pool. Thyroid hormones and insulin negatively regulate SHBG gene expression; thus, hypothyroidism or hyperinsulinemia typically lowers SHBG, increasing free hormone fractions. Conversely, estrogen often increases SHBG synthesis, altering the equilibrium of active hormone delivery.
