Genes affected
LRP4 (HGNC:6696): (LDL receptor related protein 4) This gene encodes a member of the low-density lipoprotein receptor-related protein family. The encoded protein may be a regulator of Wnt signaling. Mutations in this gene are associated with Cenani-Lenz syndrome. [provided by RefSeq, May 2010]

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Jul 26, 2022 | This sequence change replaces tryptophan, which is neutral and slightly polar, with glycine, which is neutral and non-polar, at codon 419 of the LRP4 protein (p.Trp419Gly). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with LRP4-related conditions. ClinVar contains an entry for this variant (Variation ID: 535800). 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. - |
