Department of Pathology and Laboratory Medicine,Sinai Health System RCV001356023 SCV001551075 uncertain significance not provided no assertion criteria provided clinical testing The DNAH5 p.Gly4202Ser 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: rs748903850) and in control databases in 2 of 250916 chromosomes at a frequency of 0.000008 (Genome Aggregation Database Feb 27, 2017). The variant was observed in the European (non-Finnish) population in 2 of 113318 chromosomes (freq: 0.000018), while the variant was not observed in the African, Latino, Ashkenazi Jewish, East Asian, European (Finnish), Other, and South Asian populations. The p.Gly4202 residue is conserved in mammals and computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) provide inconsistent predictions regarding the impact to the protein; this information is not very predictive of 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.
