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.338G>A (p.R113H) alteration is located in exon 3 (coding exon 3) of the HGFAC gene. This alteration results from a G to A substitution at nucleotide position 338, causing the arginine (R) at amino acid position 113 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
