Genes affected
SHBG (HGNC:10839): (sex hormone binding globulin) This gene encodes a steroid binding protein that was first described as a plasma protein secreted by the liver but is now thought to participate in the regulation of steroid responses. The encoded protein transports androgens and estrogens in the blood, binding each steroid molecule as a dimer formed from identical or nearly identical monomers. Polymorphisms in this gene have been associated with polycystic ovary syndrome and type 2 diabetes mellitus. Alternative splicing results in multiple transcript variants.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 25, 2022The c.115G>A (p.A39T) alteration is located in exon 2 (coding exon 2) of the SHBG gene. This alteration results from a G to A substitution at nucleotide position 115, causing the alanine (A) at amino acid position 39 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
