GeneDx RCV000760398 SCV000890271 pathogenic not provided 2018-11-27 criteria provided, single submitter clinical testing The R2319X nonsense variant in the LAMA2 gene has been reported previously in the homozygous and compound heterozygous states in individuals with congenital muscular dystrophies (Pegoraro et al., 1998; Hayashi et al., 2001); Oliveira et al.,2018). This pathogenic variant is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay. The R2319X variant is not observed at a significant frequency in large population cohorts (Lek et al., 2016). Therefore, we intepret R2319X as a pathogenic variant.
