Uncertain significance, no assertion criteria provided | clinical testing | Department of Pathology and Laboratory Medicine, Sinai Health System | - | The KDR p.Arg57Thr variant was not identified in the literature nor was it identified in LOVD 3.0. The variant was identified in dbSNP (ID: rs139047809), ClinVar (submitted by ITMI with no classification) and Cosmic (FATHM prediction: pathogenic; score=0.98). The variant was also identified in control databases in 349 of 282816 chromosomes (5 homozygous) at a frequency of 0.001234 increasing the likelihood this could be a low frequency benign variant (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: Ashkenazi Jewish in 39 of 10370 chromosomes (freq: 0.003761), South Asian in 111 of 30616 chromosomes (freq: 0.003626), Other in 12 of 7226 chromosomes (freq: 0.001661), European (Finnish) in 32 of 25122 chromosomes (freq: 0.001274), Latino in 39 of 35410 chromosomes (freq: 0.001101), European (non-Finnish) in 115 of 129168 chromosomes (freq: 0.00089) and African in 1 of 24950 chromosomes (freq: 0.00004), but was not observed in the East Asian population. The p.Arg57 residue is conserved in mammals but not in more distantly related organisms, and four out of five computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) suggest that the variant may impact the protein; however, this information is not predictive enough to assume pathogenicity. 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. - |
