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]

This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 188 of the LRP4 protein (p.Ala188Val). This variant is present in population databases (rs772245536, gnomAD 0.004%). 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: 435786). An algorithm developed to predict the effect of missense changes on protein structure and function outputs the following: PolyPhen-2: "Benign". The valine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. -
