Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	RCV000040137	SCV000063828	uncertain significance	not specified	2015-05-26	criteria provided, single submitter	clinical testing	Variant classified as Uncertain Significance - Favor Benign. The p.Pro9577Leu va riant in TTN has been identified by our laboratory in 1 Caucasian child with con centric HCM. It has also been identified in 0.5% (4/680) of East Asian chromosom es and 0.1% (9/7916) of South Asian chromosomes by the Exome Aggregation Consort ium (ExAC, http://exac.broadinstitute.org; dbSNP rs146400809). Computational pre diction tools and conservation analysis do not provide strong support for or aga inst an impact to the protein. In summary, while the clinical significance of th e p.Pro9577Leu variant is uncertain, its frequency suggests that it is more like ly to be benign.

Illumina Laboratory Services, Illumina	RCV001134275	SCV001294010	uncertain significance	Dilated cardiomyopathy 1G	2018-01-13	criteria provided, single submitter	clinical testing	This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease.
Illumina Laboratory Services, Illumina	RCV001134276	SCV001294011	benign	Myopathy, myofibrillar, 9, with early respiratory failure	2018-01-13	criteria provided, single submitter	clinical testing	This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease.
