Genes affected

INHBC (HGNC:6068): (inhibin subunit beta C) 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 homodimeric and heterodimeric activin complexes. The heterodimeric complex may function in the inhibition of activin A signaling. Transgenic mice overexpressing this gene exhibit defects in testis, liver and prostate.

Collection Method: clinical testing

The c.914A>G (p.N305S) alteration is located in exon 2 (coding exon 2) of the INHBC gene. This alteration results from a A to G substitution at nucleotide position 914, causing the asparagine (N) at amino acid position 305 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
