Description

The p.E25623Q variant (also known as c.76867G>C), located in coding exon 185 of the TTN gene, results from a G to C substitution at nucleotide position 76867. The glutamic acid at codon 25623 is replaced by glutamine, an amino acid with highly similar properties. This amino acid position is highly 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.
