Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	RCV000155016	SCV000204699	likely benign	not specified	2013-08-22	criteria provided, single submitter	clinical testing	Ala529Thr in exon 10 of TTN: This variant is not expected to have clinical signi ficance due to a lack of conservation in mammals and across species. Of note, >1 0 mammals have a threonine (Thr; this variant) at this position despite high nea rby amino acid conservation. In addition, computational analyses (AlignGVGD, Pol yPhen2, SIFT) do not suggest a high likelihood of impact to the protein. This va riant has been identified in 1/4398 African American chromosomes and 1/8592 Euro pean American chromosomes from a broad population by the NHLBI Exome Sequencing Project (http://evs.gs.washington.edu/EVS/; dbSNP rs143030869).
Illumina Laboratory Services, Illumina	RCV000345372	SCV000425240	likely benign	Tibial muscular dystrophy	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 likely benign is not then subjected to further curation. The score for this variant resulted in a classification of likely benign for this disease.
Illumina Laboratory Services, Illumina	RCV000305734	SCV000425242	uncertain significance	Early-onset myopathy with fatal cardiomyopathy	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.
