Description
The SLC16A12 p.Trp203Cys variant was not identified in the literature nor was it identified in ClinVar. The variant was identified in dbSNP (ID: rs780179198) and in control databases in 2 of 251050 chromosomes at a frequency of 0.000007967 (Genome Aggregation Database March 6, 2019, v2.1.1). The variant was observed in the following populations: Other in 1 of 6120 chromosomes (freq: 0.000163) and European (non-Finnish) in 1 of 113514 chromosomes (freq: 0.000009), but was not observed in the African, Latino, Ashkenazi Jewish, East Asian, European (Finnish), or South Asian populations. The p.Trp203 residue is conserved in mammals but not in more distantly related organisms, and 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.
