Genes affected

INHBA (HGNC:6066): (inhibin subunit beta A) 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. The encoded protein also plays a role in eye, tooth and testis development. Elevated expression of this gene may be associated with cancer cachexia in human patients. [provided by RefSeq, Aug 2016]

The c.1184A>G (p.K395R) alteration is located in exon 3 (coding exon 2) of the INHBA gene. This alteration results from a A to G substitution at nucleotide position 1184, causing the lysine (K) at amino acid position 395 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
