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 tryptophan with serine at codon 1186 of the LRP4 protein (p.Trp1186Ser). The tryptophan residue is highly conserved and there is a large physicochemical difference between tryptophan and serine. This variant is not present in population databases (ExAC no frequency). This variant has been observed to be de novo in an individual affected with sclerosteosis (PMID: 21471202). ClinVar contains an entry for this variant (Variation ID: 30410). Experimental studies have shown that this missense change impairs LRP4 protein function in vitro (PMID: 21471202, 24234652). 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. -
