    A Novel PORCN Frameshift Mutation Leading to Focal Dermal Hypoplasia: A Case Report.
    Cytogenet Genome Res 2018 Mar 10. Epub 2018 Mar 10.
    Focal dermal hypoplasia (FDH), also known as Goltz-Gorlin syndrome, is a rare, multisystemic, X-linked dominant genodermatosis characterized by defective development of mesodermal and ectodermal tissues. Major clinical features of the disorder are skin manifestations, skeletal defects, and developmental eye abnormalities. FDH is caused by heterozygous mutations in the PORCN gene located at Xp11.

    An fatty acylation assay reveals a mechanism for Wnt recognition by the acyltransferase Porcupine.
    J Biol Chem 2017 08 27;292(33):13507-13513. Epub 2017 Jun 27.
    From the Cell Biology Program and
    Wnt proteins are a family of secreted signaling proteins that play key roles in regulating cell proliferation in both embryonic and adult tissues. Production of active Wnt depends on attachment of palmitoleate, a monounsaturated fatty acid, to a conserved serine by the acyltransferase Porcupine (PORCN). Studies of PORCN activity relied on cell-based fatty acylation and signaling assays as no direct enzyme assay had yet been developed. Read More

    A non-mosaic mutation in a male with severe congenital anomalies overlapping focal dermal hypoplasia.

    Genetically engineered mouse models to evaluate the role of Wnt secretion in bone development and homeostasis.
    Am J Med Genet C Semin Med Genet 2016 Mar 28;172C(1):24-6. Epub 2016 Jan 28.
    Alterations in components of the Wnt signaling pathway are associated with altered bone development and homeostasis in several human diseases. We created genetically engineered mouse models (GEMMs) that mimic the cellular defect associated with the Porcupine mutations in patients with Goltz Syndrome/Focal Dermal Hypoplasia. These GEMMs were established by utilizing mice containing a conditionally inactivatable allele of Wntless/GPR177 (a gene encoding a protein required for the transport of Porcupine-modified ligand to the plasma membrane for secretion).

    Focal dermal hypoplasia (Goltz syndrome; GS) is an X-linked dominant disorder caused by a mutation in the porcupine homolog (PORCN) gene and is typically embryonically lethal for males. The presence of disease in males is usually the result of post-zygotic mutation, but may also be due to mosaicism. The presentation of this disorder is highly variable, but generally is characterized by cutaneous, skeletal, ocular, oral, dental, and aural defects. Read More
