Description

The p.P64L variant (also known as c.191C>T), located in coding exon 1 of the TGFB2 gene, results from a C to T substitution at nucleotide position 191. The proline at codon 64 is replaced by leucine, an amino acid with similar properties. This amino acid position is conserved. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
