Description

The p.P152R variant (also known as c.455C>G), located in coding exon 3 of the SMAD3 gene, results from a C to G substitution at nucleotide position 455. The proline at codon 152 is replaced by arginine, an amino acid with dissimilar properties. This amino acid position is conserved. In addition, the in silico prediction for this alteration is inconclusive. Based on the available evidence, the clinical significance of this alteration remains unclear.
