Description

p.Arg5His in exon 1 of TTR: This variant is not expected to have clinical signif icance due to a lack of conservation across species, including mammals. Of note, >15 mammals, including chimpanzee, have a histidine (His) at this position. Thi s variant has been identified in 21/126636 European chromosomes, including 1 hom ozygote, by the Genome Aggregation Database (gnomAD, http://gnomad.broadinstitut e.org; dbSNP rs138657343).
