RCV000219152 | SCV000271126 | likely benign | not specified | 2015-06-24 | criteria provided, single submitter | clinical testing | p.Ile31959Thr in exon 207 of TTN: This variant is not expected to have clinical significance due to a lack of conservation across species, including mammals. Of note, >50 mammals have a threonine (Thr) at this position despite high nearby a mino acid conservation. It has also been identified in 4/66734 European chromoso mes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; d bSNP rs370618537). |
Ambry Genetics | RCV000245827 | SCV000318234 | uncertain significance | Cardiovascular phenotype | 2013-02-18 | criteria provided, single submitter | clinical testing | ​The p.I31959T variant (also known as c.95876T>C) is located in coding exon 306 of the TTN gene. This alteration results from a T to C substitution at nucleotide position 95876. The isoleucine at codon 31959 is replaced by threonine, an amino acid with similar properties. This variant was observed in conjunction with a pathogenic PKP2 mutation in a proband tested by our labortory who is affected with ADHD, sudden cardiac arrest and syncope. Based on data from the NHLBI Exome Sequencing Project (ESP), the C-allele has an overall frequency of approximately 0.01% (1/12,060), having been observed in 0% (0/3820) of African American alleles, and in 0.01% (1/8240) of European American alleles. Based on protein sequence alignment, this amino acid position is poorly conserved in available vertebrate species. In addition, this alteration is predicted to be benign by PolyPhen in silico analysis. Since supporting evidence is limited at this time, the clinical significance of p.I31959T remains unclear. |
