Description

The p.L529S variant (also known as c.1586T>C), located in coding exon 11 of the SMAD4 gene, results from a T to C substitution at nucleotide position 1586. The leucine at codon 529 is replaced by serine, an amino acid with dissimilar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
