RCV000177234 | SCV001552556 | likely benign | not provided | no assertion criteria provided | clinical testing | The EPM2A p.Ala227Val variant was not identified in the literature nor was it identified in LOVD 3.0. The variant was identified in dbSNP (ID: rs147399860) and ClinVar (classified as uncertain significance by EGL Genetics, Ambry Genetics and Invitae, and as likely benign by GeneDx and Center for Pediatric Genomic Medicine, Children's Mercy Hospital and Clinics). The variant was identified in control databases in 317 of 282824 chromosomes (2 homozygous) at a frequency of 0.001121 increasing the likelihood this could be a low frequency benign variant (Genome Aggregation Database March 6, 2019, v2.1.1). The variant was observed in the following populations: Other in 13 of 7222 chromosomes (freq: 0.0018), European (non-Finnish) in 224 of 129136 chromosomes (freq: 0.001735), Latino in 52 of 35438 chromosomes (freq: 0.001467), Ashkenazi Jewish in 9 of 10368 chromosomes (freq: 0.000868), South Asian in 11 of 30616 chromosomes (freq: 0.000359), African in 4 of 24966 chromosomes (freq: 0.00016) and European (Finnish) in 4 of 25124 chromosomes (freq: 0.000159), but was not observed in the East Asian population. The p.Ala227 residue is not conserved in mammals and computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) do not suggest a high likelihood of impact to the protein; however, this information is not predictive enough to rule out 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 although we would lean towards a more benign role for this variant. This variant is classified as likely benign. |
