Genes affected

HGFAC (HGNC:4894): (HGF activator) This gene encodes a member of the peptidase S1 protein family. The encoded protein is first synthesized as an inactive single-chain precursor before being activated to a heterodimeric form by endoproteolytic processing. It acts as serine protease that converts hepatocyte growth factor to the active form. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2014]

The c.458C>T (p.P153L) alteration is located in exon 4 (coding exon 4) of the HGFAC gene. This alteration results from a C to T substitution at nucleotide position 458, causing the proline (P) at amino acid position 153 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
