Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV002238559 SCV002511430 likely pathogenic Junctional epidermolysis bullosa 2022-04-05 criteria provided, single submitter clinical testing Variant summary: LAMA3 c.1045G>T (p.Gly349X) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. Truncations downstream of this position have been classified as pathogenic by our laboratory. The variant was absent in 251400 control chromosomes (gnomAD). To our knowledge, no occurrence of c.1045G>T in individuals affected with Junctional Epidermolysis Bullosa and no experimental evidence demonstrating its impact on protein function have been reported. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014. Based on the evidence outlined above, the variant was classified as likely pathogenic.
