GeneDx RCV000598750 SCV000710694 pathogenic not provided 2018-02-28 criteria provided, single submitter clinical testing Although the c.1524_1534dup11 pathogenic variant in the LMNA gene has not been reported to our knowledge, this variant causes a shift in reading frame starting at codon leucine 512, changing it to a proline, and creating a premature stop codon at position 40 of the new reading frame, denoted p.Leu512ProfsX40. 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 downstream frameshift variants in the LMNA gene have been reported in Human Gene Mutation Database in association with LMNA-related disorders (Stenson et al., 2014), indicating that loss of function is a mechanism of disease for this gene. Furthermore, the c.1524_1534dup11 variant is not observed in large population cohorts (Lek et al., 2016).
