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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 03, 2024The c.257C>G (p.P86R) alteration is located in exon 2 (coding exon 2) of the HGFAC gene. This alteration results from a C to G substitution at nucleotide position 257, causing the proline (P) at amino acid position 86 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
