The p.L8108S variant (also known as c.24323T>C) is located in coding exon 93 of the TTNgene. This alteration results from a T to C substitution at nucleotide position 24323. The leucine at codon 8108 is replaced by serine, an amino acid with dissimilar properties.This variant was not reported in population-based cohorts in the following databases: Database of Single Nucleotide Polymorphisms (dbSNP), the 1000 Genomes Project and the NHLBI Exome Sequencing Project (ESP). In the ESP, this variant was not observed in 5971 samples (11942 alleles) with coverage at this position.Based on protein sequence alignment, this amino acid position is not well conserved in available vertebrate species. In addition, this alteration is predicted to be possibly damaging by PolyPhen in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this variant remains unclear.
