GeneDx RCV000613965 SCV000731140 likely benign not specified 2018-02-27 criteria provided, single submitter clinical testing This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease.

Department of Pathology and Laboratory Medicine, Sinai Health System RCV001356962 SCV001552269 likely benign not provided no assertion criteria provided clinical testing The ABCC6 c.662+12C>T variant was not identified in the literature nor was it identified in the Cosmic database. The variant was identified in dbSNP (ID: rs72664291), ClinVar (reported likely benign by GeneDx and pathogenic by PXE International), Clinvitae, and LOVD 3.0 (classified as benign). The variant was identified in control databases in 2838 of 169536 chromosomes (42 homozygous) at a frequency of 0.01674 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: European (non-Finnish) in 1691 of 65948 chromosomes (freq: 0.02564), Other in 93 of 4902 chromosomes (freq: 0.01897), European (Finnish) in 326 of 18338 chromosomes (freq: 0.01778), South Asian in 310 of 21710 chromosomes (freq: 0.01428), Ashkenazi Jewish in 103 of 7726 chromosomes (freq: 0.01333), Latino in 256 of 24756 chromosomes (freq: 0.01034), African in 44 of 13714 chromosomes (freq: 0.003208), and East Asian in 15 of 12442 chromosomes (freq: 0.001206). The c.662+12C>T variant is not expected to have clinical significance because it does not result in a change of amino acid and is not located in a known consensus splice site. In addition, in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, and 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.
