Submissions by phenotype

not provided Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpSep 09, 2021This variant has not been reported in the literature in individuals affected with LRRC34-related conditions. This variant is present in population databases (rs143470723, ExAC 0.02%). This sequence change replaces arginine with histidine at codon 297 of the LRRC34 protein (p.Arg297His). The arginine residue is moderately conserved and there is a small physicochemical difference between arginine and histidine. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
