Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Feb 05, 2019 | The p.L21086F variant (also known as c.63256C>T), located in coding exon 162 of the TTN gene, results from a C to T substitution at nucleotide position 63256, and is located in the A-band region of the N2-B isoform of the titin protein. The leucine at codon 21086 is replaced by phenylalanine, an amino acid with highly similar properties. This amino acid position is not well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this variant remains unclear. - |
