Department of Pathology and Laboratory Medicine, Sinai Health System RCV001357118 SCV001552475 uncertain significance not provided no assertion criteria provided clinical testing The TTN p.Thr18915Ile variant was not identified in the literature nor was it identified in ClinVar, Cosmic or LOVD 3.0. The variant was identified in dbSNP (ID: rs1268315067) and in control databases in 1 of 31398 chromosomes at a frequency of 0.000032 (Genome Aggregation Database Feb 27, 2017). The variant was observed in the African population in 1 of 8716 chromosomes (freq: 0.000115), while the variant was not observed in the Latino, Ashkenazi Jewish, East Asian, European (Finnish), European (non-Finnish), Other or South Asian populations. Three out of four computational analyses (PolyPhen-2, SIFT, MutationTaster) do not suggest that the variant will impact the protein. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) do not predict a difference in splicing. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time. This variant is classified as a variant of uncertain significance.
