Genes affected

ZNF687 (HGNC:29277): (zinc finger protein 687) This gene encodes C2H2 zinc finger protein. The encoded protein may play a role in bone differentiation and development. Mutations in this gene are the cause of Paget disease of bone-6. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Sep 2016]

This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 937 of the ZNF687 protein (p.Pro937Leu). This variant is present in population databases (rs148402804, gnomAD 0.06%). This variant has not been reported in the literature in individuals affected with ZNF687-related conditions. ClinVar contains an entry for this variant (Variation ID: 1518826). 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. -

Variant summary: ZNF687 c.2810C>T (p.Pro937Leu) results in a non-conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.00012 in 175820 control chromosomes. This frequency is not significantly higher than estimated for a pathogenic variant in ZNF687 causing Paget Disease Of Bone 6, allowing no conclusion about variant significance. To our knowledge, no occurrence of c.2810C>T in individuals affected with Paget Disease Of Bone 6 and no experimental evidence demonstrating its impact on protein function have been reported. ClinVar contains an entry for this variant (Variation ID: 1518826). Based on the evidence outlined above, the variant was classified as uncertain significance. -
