Description

The p.D10035E variant (also known as c.30105T>G), located in coding exon 121 of the TTN gene, results from a T to G substitution at nucleotide position 30105. The aspartic acid at codon 10035 is replaced by glutamic acid, an amino acid with highly similar properties. This amino acid position is not well conserved in available vertebrate species, and glutamic acid is the reference amino acid in other 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.
