GeneDx	RCV000174037	SCV000512439	benign	not specified	2016-09-16	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.
Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	RCV000174037	SCV000538548	benign	not specified	2016-10-31	criteria provided, single submitter	clinical testing	Variant identified in a genome or exome case(s) and assessed due to predicted null impact of the variant or pathogenic assertions in the literature or databases. Disclaimer: This variant has not undergone full assessment. The following are preliminary notes: This variant is present in ExAC at a MaxMAF of 2% in Finnish chromosomes. It is classified in ClinVar with 1 star as Benign by Emory and Likely Benign by UniProtKB/Swiss-Prot. It was reported in one patient with alternating hemiplagia of childhood who also had a de novo variant in ATP1A3, CACNA1A variant was also seen in her unaffected mother. It was seen in one family with Familial hemiplegic migraine (segregated in 1 relative) and was associated with the absence of sensorimotor symptoms in a migraine with aura. In the same paper, authors show via in vitro studies that this variant affected protein function. Was also seen in one proband with early-onset progressive ataxia and her affected sister. If this variant plays any role in disease, its frequnecy is too high to be a Mendelian variant.

Ambry Genetics	RCV002313741	SCV000848039	benign	Inborn genetic diseases	2016-09-13	criteria provided, single submitter	clinical testing	This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity.
