Genes affected

GDF11 (HGNC:4216): (growth differentiation factor 11) This gene encodes a secreted ligand of the TGF-beta (transforming growth factor-beta) superfamily of proteins. Ligands of this family bind various TGF-beta receptors leading to recruitment and activation of SMAD family transcription factors that regulate gene expression. The encoded preproprotein is proteolytically processed to generate each subunit of the disulfide-linked homodimer. This protein plays a role in the development of the nervous and other organ systems, and may regulate aging. [provided by RefSeq, Aug 2016]

The c.835G>A (p.E279K) alteration is located in exon 2 (coding exon 2) of the GDF11 gene. This alteration results from a G to A substitution at nucleotide position 835, causing the glutamic acid (E) at amino acid position 279 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
