Submissions by phenotype

not provided Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingInvitaeMar 14, 2022This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 537 of the LMF1 protein (p.Arg537Gln). This variant is present in population databases (rs533542876, gnomAD 0.03%). This variant has not been reported in the literature in individuals affected with LMF1-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. 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. -
