Uncertain significance, criteria provided, single submitter | clinical testing | GeneDx | Jul 28, 2017 | A variant of uncertain significance has been identified in the LAMA2 gene. The R2001K variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. The R2001K variant is observed in 29/8596 (0.3%) alleles from individuals of East Asian background (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). This substitution occurs at a position that is conserved across species. However, the R2001K variant is a conservative amino acid substitution, which is not likely to impact secondary protein structure as these residues share similar properties. In silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function. Therefore, based on the currently available information, it is unclear whether this variant is a pathogenic variant or a rare benign variant. - |
