Submissions by phenotype
not specified Benign:1
Likely benign, criteria provided, single submitter | clinical testing | Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine | Mar 19, 2012 | c.36577+8T>C in intron 188 of TTN: This variant is not expected to have clinical significance because it is not located within the splice consensus sequence. It has been identified in 1/2934 African American chromosomes from a broad populat ion by the NHLBI Exome Sequencing Project (http://evs.gs.washington.edu/EVS). - |

not provided Benign:1
Likely benign, criteria provided, single submitter | clinical testing | GeneDx | May 23, 2018 | This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. - |
