Genes affected

INHBB (HGNC:6067): (inhibin subunit beta B) This gene encodes a member of the TGF-beta (transforming growth factor-beta) superfamily of proteins. The encoded preproprotein is proteolytically processed to generate a subunit of the dimeric activin and inhibin protein complexes. These complexes activate and inhibit, respectively, follicle stimulating hormone secretion from the pituitary gland. Polymorphisms near this gene are associated with pre-eclampsia in female human patients. [provided by RefSeq, Aug 2016]

The c.214G>C (p.G72R) alteration is located in exon 1 (coding exon 1) of the INHBB gene. This alteration results from a G to C substitution at nucleotide position 214, causing the glycine (G) at amino acid position 72 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
