Further evidence of POP1 mutations as the cause of anauxetic dysplasia.
American Journal of Medical Genetics Part A 170(9):2462 (2016)
Anauxetic dysplasia (AAD, OMIM 607095) is a rare skeletal dysplasia inherited as an autosomal recessive trait, which is caused by mutations in RMRP and allelic to a more common disorder, cartilage hair hypoplasia (CHH). CHH is a multi-system disorder with a variety of extraskeletal changes. Wher...
Diagnosis of Van den Ende-Gupta syndrome: Approach to the Marden-Walker-like spectrum of disorders.
American Journal of Medical Genetics Part A 170(9):2310 (2016)
Marden-Walker syndrome is challenging to diagnose, as there is significant overlap with other multi-system congenital contracture syndromes including Beals congenital contractural arachnodactyly, D4ST1-Deficient Ehlers-Danlos syndrome (adducted thumb-clubfoot syndrome), Schwartz-Jampel syndrome,...

Identification of biallelic LRRK1 mutations in osteosclerotic metaphyseal dysplasia and evidence for locus heterogeneity.
Journal of Medical Genetics 53(8):568 (2016)
Osteosclerotic metaphyseal dysplasia (OSMD) is a unique form of osteopetrosis characterised by severe osteosclerosis localised to the bone ends. The mode of inheritance is autosomal recessive. Its genetic basis is not known.
To identify the disease gene for OSMD.
By whole exome sequencing in a b...
Distinctive skeletal phenotype in high bone mass osteogenesis imperfecta due to a COL1A2 cleavage site mutation.

NANS-mediated synthesis of sialic acid is required for brain and skeletal development.
Nature Genetics 48(7):777 (2016)
We identified biallelic mutations in NANS, the gene encoding the synthase for N-acetylneuraminic acid (NeuNAc; sialic acid), in nine individuals with infantile-onset severe developmental delay and skeletal dysplasia. Patient body fluids showed an elevation in N-acetyl-D-mannosamine levels, and p...

Cortical-Bone Fragility--Insights from sFRP4 Deficiency in Pyle's Disease.
New England Journal of Medicine 374(26):2553 (2016)
Cortical-bone fragility is a common feature in osteoporosis that is linked to nonvertebral fractures. Regulation of cortical-bone homeostasis has proved elusive. The study of genetic disorders of the skeleton can yield insights that fuel experimental therapeutic approaches to the treatment of ra...
BGN Mutations in X-Linked Spondyloepimetaphyseal Dysplasia.
The American Journal of Human Genetics 98(6):1243 (2016)
Spondyloepimetaphyseal dysplasias (SEMDs) comprise a heterogeneous group of autosomal-dominant and autosomal-recessive disorders. An apparent X-linked recessive (XLR) form of SEMD in a single Italian family was previously reported. We have been able to restudy this family together with a second ...
Criteria for radiologic diagnosis of hypochondroplasia in neonates.
Pediatric Radiology 46(4):513 (2016)
A radiologic diagnosis of hypochondroplasia is hampered by the absence of age-dependent radiologic criteria, particularly in the neonatal period.
To establish radiologic criteria and scoring system for identifying neonates with fibroblast growth factor receptor 3 (FGFR3)-associated hypochondropl...
Stippled calcification in an infant with a recurrent SRCAP gene mutation.

Novel DDR2 mutation identified by whole exome sequencing in a Moroccan patient with spondylo-meta-epiphyseal dysplasia, short limb-abnormal calcification type.
American Journal of Medical Genetics Part A 170A(2):460 (2016)
Spondylo-meta-epiphyseal dysplasia (SMED), short limb-abnormal calcification type (SMED, SL-AC), is a very rare autosomal recessive disorder with various skeletal changes characterized by premature calcification leading to severe disproportionate short stature. Twenty-two patients have been repo...
A novel phenotype in N-glycosylation disorders: Gillessen-Kaesbach-Nishimura skeletal dysplasia due to pathogenic variants in ALG9.
European Journal of Human Genetics 24(2):198 (2016)
A rare lethal autosomal recessive syndrome with skeletal dysplasia, polycystic kidneys and multiple malformations was first described by Gillessen-Kaesbach et al and subsequently by Nishimura et al. The skeletal features uniformly comprise a round pelvis, mesomelic shortening of the upper limbs ...
Extending the phenotype of BMPER-related skeletal dysplasias to ischiospinal dysostosis.
Orphanet Journal of Rare Diseases 11(1):1 (2016)
Ischiospinal dysostosis (ISD) is a polytopic dysostosis characterized by ischial hypoplasia, multiple segmental anomalies of the cervicothoracic spine, hypoplasia of the lumbrosacral spine and occasionally associated with nephroblastomatosis. ISD is similar to, but milder than the lethal/semilet...
A novel type II collagen gene mutation in a family with spondyloepiphyseal dysplasia and extensive intrafamilial phenotypic diversity.
Human Genome Variation 3:16007 (2016)
The purpose of this study was to describe a family with spondyloepiphyseal dysplasia caused by a novel type II collagen gene (COL2A1) mutation and the family's phenotypic diversity. Clinical and radiographic examinations of skeletal dysplasia were conducted on seven affected family members acros...
Axial Spondylometaphyseal Dysplasia Is Caused by C21orf2 Mutations.
PLoS ONE 11(3):e0150555 (2016)
Axial spondylometaphyseal dysplasia (axial SMD) is an autosomal recessive disease characterized by dysplasia of axial skeleton and retinal dystrophy. We conducted whole exome sequencing and identified C21orf2 (chromosome 21 open reading frame 2) as a disease gene for axial SMD. C21orf2 mutations...
