The c.1 A>G variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. The c.1 A>G variant was not observed in approximately 6500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. The c.1 A>G variant alters the initiator Methionine codon, and the resultant protein would be described as p.Met1?" using a question mark to signify that it is not known if the loss of Met1 means that all protein translation is completely prevented or if an abnormal protein is produced using an alternate Met. Therefore, this variant is likely pathogenic; however, the possibility that it is benign cannot be excluded."
