The SLC25A4 p.Ile164Val variant was not identified in the literature nor was it identified in Cosmic or LOVD 3.0. The variant was identified in dbSNP (ID: rs143511445) and ClinVar (classified as likely benign by GeneDx and benign by Athena Diagnostics Inc). The variant was identified in control databases in 146 of 281816 chromosomes at a frequency of 0.000518 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: African in 135 of 24898 chromosomes (freq: 0.005422), Other in 3 of 7190 chromosomes (freq: 0.000417) and Latino in 8 of 35326 chromosomes (freq: 0.000227), while the variant was not observed in the Ashkenazi Jewish, East Asian, European (Finnish), European (non-Finnish), and South Asian populations. The p.Ile164 residue is conserved in mammals but not in more distantly related organisms and four out of five computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM) do not suggest a high likelihood of impact to the protein; this information is not predictive enough to rule out pathogenicity. The variant occurs outside of the splicing consensus sequence and 2 of 4 in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan) predict a greater than 10% difference in splicing, however 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.
