The ciliopathy-associated CPLANE proteins direct basal body recruitment of intraflagellar transport machinery.
Nature Genetics 48(6):648 (2016)
Cilia use microtubule-based intraflagellar transport (IFT) to organize intercellular signaling. Ciliopathies are a spectrum of human diseases resulting from defects in cilia structure or function. The mechanisms regulating the assembly of ciliary multiprotein complexes and the transport of these...
TGFβ and BMP Dependent Cell Fate Changes Due to Loss of Filamin B Produces Disc Degeneration and Progressive Vertebral Fusions.
PLoS Genetics 12(3):e1005936 (2016)
Spondylocarpotarsal synostosis (SCT) is an autosomal recessive disorder characterized by progressive vertebral fusions and caused by loss of function mutations in Filamin B (FLNB). FLNB acts as a signaling scaffold by linking the actin cytoskleteon to signal transduction systems, yet the disease...

HSP47 and FKBP65 cooperate in the synthesis of type I procollagen.
Human Molecular Genetics 24(7):1918 (2015)
Osteogenesis imperfecta (OI) is a genetic disorder that results in low bone mineral density and brittle bones. Most cases result from dominant mutations in the type I procollagen genes, but mutations in a growing number of genes have been identified that produce autosomal recessive forms of the ...
Mutations in DYNC2LI1 disrupt cilia function and cause short rib polydactyly syndrome.
Nature Communications 6:7092 (2015)
The short rib polydactyly syndromes (SRPSs) are a heterogeneous group of autosomal recessive, perinatal lethal skeletal disorders characterized primarily by short, horizontal ribs, short limbs and polydactyly. Mutations in several genes affecting intraflagellar transport (IFT) cause SRPS but the...
Opsismodysplasia resulting from an insertion mutation in the SH2 domain, which destabilizes INPPL1.
American Journal of Medical Genetics Part A 164A(9):2407 (2014)
Mice expressing mutant Trpv4 recapitulate the human TRPV4 disorders.
Journal of Bone and Mineral Research 29(8):1815 (2014)
Activating mutations in transient receptor potential vanilloid family member 4 (Trpv4) are known to cause a spectrum of skeletal dysplasias ranging from autosomal dominant brachyolmia to lethal metatropic dysplasia. To develop an animal model of these disorders, we created transgenic mice expres...
Patient-derived skeletal dysplasia induced pluripotent stem cells display abnormal chondrogenic marker expression and regulation by BMP2 and TGFβ1.
Stem Cells and Development 23(13):1464 (2014)
Skeletal dysplasias (SDs) are caused by abnormal chondrogenesis during cartilage growth plate differentiation. To study early stages of aberrant cartilage formation in vitro, we generated the first induced pluripotent stem cells (iPSCs) from fibroblasts of an SD patient with a lethal form of met...
Follistatin in chondrocytes: the link between TRPV4 channelopathies and skeletal malformations.
FASEB Journal 28(6):2525 (2014)
Point mutations in the calcium-permeable TRPV4 ion channel have been identified as the cause of autosomal-dominant human motor neuropathies, arthropathies, and skeletal malformations of varying severity. The objective of this study was to determine the mechanism by which TRPV4 channelopathy muta...
WNT1 mutations in early-onset osteoporosis and osteogenesis imperfecta.
New England Journal of Medicine 368(19):1809 (2013)
This report identifies human skeletal diseases associated with mutations in WNT1. In 10 family members with dominantly inherited, early-onset osteoporosis, we identified a heterozygous missense mutation in WNT1, c.652T→G (p.Cys218Gly). In a separate family with 2 siblings affected by recessive o...
Whole-genome analysis reveals that mutations in inositol polyphosphate phosphatase-like 1 cause opsismodysplasia.
The American Journal of Human Genetics 92(1):137 (2013)
Opsismodysplasia is a rare, autosomal-recessive skeletal dysplasia characterized by short stature, characteristic facial features, and in some cases severe renal phosphate wasting. We used linkage analysis and whole-genome sequencing of a consanguineous trio to discover that mutations in inosito...

Exome sequencing identifies PDE4D mutations in acrodysostosis.
The American Journal of Human Genetics 90(4):746 (2012)
Acrodysostosis is a dominantly-inherited, multisystem disorder characterized by skeletal, endocrine, and neurological abnormalities. To identify the molecular basis of acrodysostosis, we performed exome sequencing on five genetically independent cases. Three different missense mutations in PDE4D...
Peptidyl 3-hydroxyproline binding properties of type I collagen suggest a function in fibril supramolecular assembly.
Biochemistry (Washington) 51(12):2417 (2012)
Proline residues in collagens are extensively hydroxylated post-translationally. A rare form of this modification, (3S,2S)-l-hydroxyproline (3Hyp), remains without a clear function. Disruption of the enzyme complex responsible for prolyl 3-hydroxylation results in severe forms of recessive osteo...
Dominant and recessive forms of fibrochondrogenesis resulting from mutations at a second locus, COL11A2.
American Journal of Medical Genetics Part A 158A(2):309 (2012)
Fibrochondrogenesis is a severe, recessively inherited skeletal dysplasia shown to result from mutations in the gene encoding the proα1(XI) chain of type XI collagen, COL11A1. The first of two cases reported here was the affected offspring of first cousins and sequence analysis excluded mutation...
The importance of conventional radiography in the mutational analysis of skeletal dysplasias (the TRPV4 mutational family).
Pediatric Radiology 42(1):15 (2012)
The spondylo and spondylometaphyseal dysplasias (SMDs) are characterized by vertebral changes and metaphyseal abnormalities of the tubular bones, which produce a phenotypic spectrum of disorders from the mild autosomal-dominant brachyolmia to SMD Kozlowski to autosomal-dominant metatropic dyspla...
Recurrent dominant mutations affecting two adjacent residues in the motor domain of the monomeric kinesin KIF22 result in skeletal dysplasia and joint laxity.
