Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Aug 18, 2020 | The p.A8144T variant (also known as c.24430G>A), located in coding exon 99 of the TTN gene, results from a G to A substitution at nucleotide position 24430. The alanine at codon 8144 is replaced by threonine, an amino acid with similar properties. This amino acid position is not 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. - |
