Invitae | RCV000814057 | SCV000954452 | uncertain significance | Pierson syndrome; LAMB2-related infantile-onset nephrotic syndrome | 2022-11-29 | criteria provided, single submitter | clinical testing | 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. 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. ClinVar contains an entry for this variant (Variation ID: 657455). This missense change has been observed in individual(s) with IgA nephropathy (PMID: 26248470). This variant is present in population databases (rs780366815, gnomAD 0.007%). This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 1564 of the LAMB2 protein (p.Arg1564Trp). |
