Genes affected

GAS6 (HGNC:4168): (growth arrest specific 6) This gene encodes a gamma-carboxyglutamic acid (Gla)-containing protein thought to be involved in the stimulation of cell proliferation. This gene is frequently overexpressed in many cancers and has been implicated as an adverse prognostic marker. Elevated protein levels are additionally associated with a variety of disease states, including venous thromboembolic disease, systemic lupus erythematosus, chronic renal failure, and preeclampsia.

The c.1801G>A (p.A601T) alteration is located in exon 14 (coding exon 14) of the GAS6 gene. This alteration results from a G to A substitution at nucleotide position 1801, causing the alanine (A) at amino acid position 601 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
