The variant was identified in dbSNP (ID: rs146100407) and in LOVD 3.0 (variant is classified as likely benign). The variant was also identified in control databases in 113 of 282810 chromosomes at a frequency of 0.0004 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 110 of 24964 chromosomes (freq: 0.004406), Latino in 2 of 35436 chromosomes (freq: 0.000056) and European (non-Finnish) in 1 of 129132 chromosomes (freq: 0.000008); it was not observed in the Ashkenazi Jewish, East Asian, European (Finnish), Other or South Asian populations.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 at the variant location. The p.Ala60 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. 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.
