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]

Collection Method:clinical testing

This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 202 of the LRP4 protein (p.Arg202His). This variant is present in population databases (rs149056824, gnomAD 0.01%). 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: 582703). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬†is likely to be tolerated. 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. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.605G>A (p.R202H) alteration is located in exon 6 (coding exon 6) of the LRP4 gene. This alteration results from a G to A substitution at nucleotide position 605, causing the arginine (R) at amino acid position 202 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
