RCV000154955 | SCV000204637 | uncertain significance | not specified | 2013-07-17 | criteria provided, single submitter | clinical testing | The Lys11090Arg variant in TTN has not been reported in individuals with cardiom yopathy, but has been identified in 2/8212 European American chromosomes by the NHLBI Exome Sequencing Project (http://evs.gs.washington.edu/EVS/; dbSNP rs18471 321). Computational analyses (biochemical amino acid properties, conservation, A lignGVGD, PolyPhen2, and SIFT) do not provide strong support for or against an i mpact to the protein. Additional information is needed to fully assess the clini cal significance of this variant. |

RCV001134532 | SCV001294279 | uncertain significance | Autosomal recessive limb-girdle muscular dystrophy type 2J | 2017-04-27 | criteria provided, single submitter | clinical testing | This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases did not allow this variant to be ruled in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. |

RCV001135957 | SCV001295769 | benign | Tibial muscular dystrophy | 2017-04-27 | criteria provided, single submitter | clinical testing | This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases was too high to be consistent with this variant causing disease. Therefore, this variant is classified as benign. |

RCV000154955 | SCV001821501 | likely benign | not specified | 2024-07-30 | criteria provided, single submitter | clinical testing | Variant summary: TTN c.33269A>G (p.Lys11090Arg) results in a conservative amino acid change located in the I-band region of the encoded protein sequence. Five of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.00014 in 1602136 control chromosomes in the gnomAD database (v4.1 dataset). In addition, within the South Asian subpopulation (allele frequency: 0.00037) the variant was fond in 1 homozygote. Furthermore, in certain ethnicities, e.g. in the Middle Eastern, the variant was reported with an even higher frequency (i.e. 0.0025), and which is about 6-times higher than the estimated maximum expected for a pathogenic variant in TTN causing Dilated Cardiomyopathy (0.00039), suggesting that the variant might be benign. The variant, c.33269A>G, has been reported in the literature in one individual affected with hypertrophic cardiomyopathy (Lopes_2013). These report(s) do not provide unequivocal conclusions about association of the variant with Dilated Cardiomyopathy. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publication have been ascertained in the context of this evaluation (PMID: 23396983). ClinVar contains an entry for this variant (Variation ID: 178220). Based on the evidence outlined above, the variant was classified as likely benign. |
