RCV001357886 | SCV001553481 | uncertain significance | not provided | no assertion criteria provided | clinical testing | The DNAH11 p.Val2454Leu variant was not identified in the literature nor was it identified in ClinVar. The variant was identified in dbSNP (ID: rs536942937) and in control databases in 24 of 214052 chromosomes at a frequency of 0.0001121 (Genome Aggregation Database March 6, 2019, v2.1.1). The variant was observed in the following populations: South Asian in 23 of 26208 chromosomes (freq: 0.000878) and European (non-Finnish) in 1 of 93708 chromosomes (freq: 0.000011), but was not observed in the African, Latino, Ashkenazi Jewish, East Asian, European (Finnish), or Other populations. The p.Val2454 residue is not conserved in mammals and 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 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. |
