Description

The p.S476T variant (also known as c.1427G>C), located in coding exon 9 of the KIT gene, results from a G to C substitution at nucleotide position 1427. The serine at codon 476 is replaced by threonine, an amino acid with similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
