The variant was identified in dbSNP (ID: rs148481786) and ClinVar (classified as benign by EGL Genetics and likely benign by Children's Mercy Hospital) The variant was identified in control databases in 1644 of 282350 chromosomes (14 homozygous) at a frequency of 0.005823 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: Ashkenazi Jewish in 290 of 10356 chromosomes (freq: 0.028), European (Finnish) in 249 of 25120 chromosomes (freq: 0.009912), Other in 67 of 7192 chromosomes (freq: 0.009316), European (non-Finnish) in 859 of 128920 chromosomes (freq: 0.006663), Latino in 89 of 35424 chromosomes (freq: 0.002512), South Asian in 71 of 30614 chromosomes (freq: 0.002319) and African in 19 of 24776 chromosomes (freq: 0.000767), while the variant was not observed in the East Asian population. 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. The p.Glu1006 residue is not conserved in mammals and four out of five computational analyses (PolyPhen-2, SIFT, AlignGVGD, MutationTaster) do not suggest a high likelihood of impact to the protein; however, this information is not predictive enough to rule out pathogenicity. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time although we would lean towards a more benign role for this variant. This variant is classified as likely benign.
