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.619C>T (p.L207F) alteration is located in exon 5 (coding exon 5) of the HDGF gene. This alteration results from a C to T substitution at nucleotide position 619, causing the leucine (L) at amino acid position 207 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
