Department of Pathology and Laboratory Medicine, Sinai Health System	RCV001357150	SCV001552519	uncertain significance	not provided		no assertion criteria provided	clinical testing	The PIK3C2A p.Ala595Gly variant was not identified in the literature nor was it identified in dbSNP, ClinVar or in the following control databases: the 1000 Genomes Project, the NHLBI GO Exome Sequencing Project, or the Genome Aggregation Database (March 6, 2019, v2.1.1). The p.Ala595 residue is not conserved in mammals and four out of five 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 three of four in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) do not predict a greater than 10% difference in splicing; 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.
