GeneDx RCV000353946 SCV000329402 pathogenic not provided 2017-02-27 criteria provided, single submitter clinical testing Although the c.784delG pathogenic variant in the LMNA gene has not been published to our knowledge, it has been reported in one other individual referred for cardiomyopathy testing at GeneDx. This variant causes a shift in reading frame starting at codon Glutamic acid 262, changing it to a Serine, and creating a premature stop codon at position 218 of the new reading frame, denoted p.Glu262SerfsX218. This pathogenic variant is expected to result in either an abnormal, truncated protein product or loss of protein from this allele through nonsense-mediated mRNA decay. Other frameshift variants in the LMNA gene have been reported in HGMD in association with LMNA-related disorders (Stenson et al., 2014). Furthermore, the c.784delG variant was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. In summary, c.784delG in the LMNA gene is interpreted as a pathogenic variant.
