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]

Mar 20, 2023

The c.404C>T (p.T135I) 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 404, causing the threonine (T) at amino acid position 135 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
