Genes affected

MST1 (HGNC:7380): (macrophage stimulating 1) The protein encoded by this gene contains four kringle domains and a serine protease domain, similar to that found in hepatic growth factor. Despite the presence of the serine protease domain, the encoded protein may not have any proteolytic activity. The receptor for this protein is RON tyrosine kinase, which upon activation stimulates ciliary motility of ciliated epithelial lung cells. This protein is secreted and cleaved to form an alpha chain and a beta chain bridged by disulfide bonds. [provided by RefSeq, Jan 2010]

The c.2108G>A (p.R703H) alteration is located in exon 18 (coding exon 18) of the MST1 gene. This alteration results from a G to A substitution at nucleotide position 2108, causing the arginine (R) at amino acid position 703 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
