The TDRD9 p.C98G 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: rs755011079) and in control databases in 10 of 188112 chromosomes at a frequency of 0.000053 (Genome Aggregation Database Feb 27, 2017). The variant was observed in the European (non-Finnish) population in 10 of 76128 chromosomes (freq: 0.000131), but was not observed in the African, Latino, Ashkenazi Jewish, East Asian, European (Finnish), Other or South Asian populations. The p.Cys98 residue is not conserved in mammals and four out of five computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) do not suggest a high likelihood of impact to the protein; however, this information is not predictive enough to rule out pathogenicity. The variant occurs outside of the splicing consensus sequence and two of four in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) predict a greater than 10% difference in splicing; this is not very predictive of pathogenicity. 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. -
