GeneDx RCV000413690 SCV000492122 uncertain significance not specified 2016-11-30 criteria provided, single submitter clinical testing One individual with Leber congenital amaurosis (LCA) has been reported to be homozygous for the E3414G variant (published using alternative nomenclature E3412G) in the ALMS1 gene, though neither deletion analysis of the ALMS1 gene nor parental consanguinity status or genotypes were reported (Wang et al., 2015). Furthermore, this individual was also apparently homozygous for a truncating variant in the LCA5 gene, which would better explain a typical LCA phenotype. The E3414G variant is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. Though E3414G variant was not observed with any significant frequency in over 80,000 individuals of European and African ancestry in the Exome Aggregation Consortium, it was reported in 42/8554 (0.5%) alleles in individuals of East Asian background. Additionally, this substitution occurs at a position that is not conserved across species. In silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function. Lastly, while some missense variants have been reported in association with Alstrom syndrome, most pathogenic variants in ALMS1 reported to date introduce a premature termination codon (Marshall et al., 2012; Stenson et al., 2014).
