Genes affected

HDGF (HGNC:4856): (heparin binding growth factor) This gene encodes a member of the hepatoma-derived growth factor family. The encoded protein has mitogenic and DNA-binding activity and may play a role in cellular proliferation and differentiation. High levels of expression of this gene enhance the growth of many tumors. This gene was thought initially to be located on chromosome X; however, that location has been determined to correspond to a related pseudogene. Alternatively spliced transcript variants encoding distinct isoforms have been described. [provided by RefSeq, Jan 2016]

The c.557A>G (p.K186R) alteration is located in exon 5 (coding exon 5) of the HDGF gene. This alteration results from a A to G substitution at nucleotide position 557, causing the lysine (K) at amino acid position 186 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
