Description

The p.R266H variant (also known as c.797G>A), located in coding exon 5 of the TGFB3 gene, results from a G to A substitution at nucleotide position 797. The arginine at codon 266 is replaced by histidine, an amino acid with highly similar properties. This amino acid position is well conserved in available vertebrate species. 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.
