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.

The c.413T>C (p.V138A) alteration is located in exon 2 (coding exon 2) of the INHBC gene. This alteration results from a T to C substitution at nucleotide position 413, causing the valine (V) at amino acid position 138 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
