Comment on publications: added PMID 28100910 further evidence to support gene-phenotype which reports a 11-year-old female with PYL, and found a novel homozygous nonsense variant, c.183C>G (p.Y61*). Segregation analysis in the patient revealed a germline mutation, resulting in reduced protein formation. This is the second report from a fourth affected family with a SFRP4 mutation causing PYL disease.

Comment on list classification: PMID:27355534 - A brother and sister with Pyle disease were homozygous for a frameshift variant in this gene, with unaffected parents and brother heterozygous. An additional two unrelated cases with loss of function variants are reported, however without evidence of segregation. These variants were identified with a variant filtering pipeline for rare variants. Features similar to Pyle disease were observed in knockout mice. Treatment of Sfrp4-deficient mice with a soluble Bmp2 receptor (RAP-661) or with antibodies to sclerostin corrected the cortical-bone defect. Other publications contribute evidence towards the role of this gene in bone density, skeletal development and the Wnt signalling pathway.
