Invitae RCV000557240 SCV000651558 uncertain significance Pierson syndrome; LAMB2-related infantile-onset nephrotic syndrome 2016-12-21 criteria provided, single submitter clinical testing In summary, this variant is a rare missense change that is not predicted to affect protein function. There is no indication that it causes disease, but the available evidence is currently insufficient to prove that conclusively. Therefore, it has been classified as a Variant of Uncertain Significance. 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 tolerated, but these predictions have not been confirmed by published functional studies. This variant is present in population databases (rs768491835, ExAC 0.009%) but has not been reported in the literature in individuals with a LAMB2-related disease. This sequence change replaces glutamic acid with glycine at codon 1584 of the LAMB2 protein (p.Glu1584Gly). The glutamic acid residue is highly conserved and there is a moderate physicochemical difference between glutamic acid and glycine.
