OBJECTIVE
To characterize a kindred of Chiloe Islanders with spondyloepiphyseal dysplasia tarda (SEDT), brachydactyly, precocious osteoarthritis (OA), and intraarticular calcification.
METHODS
Sixteen family members underwent a complete physical examination, anthropometric measurements, radiographic
BACKGROUND
The majority of COL2A1 missense mutations are substitutions of obligatory glycine residues in the triple helical domain. Only a few non-glycine missense mutations have been reported and among these, the arginine to cysteine substitutions predominate.
OBJECTIVE
To investigate in more
Autosomal recessive Robinow syndrome (RRS) is a severe skeletal dysplasia with short stature, generalized limb shortening, segmental defects of the spine, brachydactyly, and a dysmorphic facial appearance. The gene encoding receptor orphan receptor tyrosine kinase 2 (ROR2) is located on chromosome
The term "spondyloperipheral dysplasia" (SPD) has been applied to the unusual combination of platyspondyly and brachydactyly as observed in a small number of individuals. The reported cases show wide clinical variability and the nosologic status and spectrum of this condition are still ill defined.
ROR2 is a member of the cell surface receptor tyrosine kinase (RTKs) family of proteins and is involved in the developmental morphogenesis of the skeletal, cardiovascular and genital systems. Mutations in ROR2 have been shown to cause two distinct human disorders, autosomal recessive Robinow
Receptor tyrosine kinases (RTKs) play crucial roles in various developmental processes. Ror-family RTKs are characterized by the intracellular tyrosine kinase domains, highly related to those of the Trk-family RTKs, and by the extracellular Frizzled-like cysteine-rich domains (CRDs) and Kringle
Proximal symphalangism (SYM1) is an autosomal dominant disorder, mainly characterized by variable fusion of the proximal interphalangeal joints of the hands and feet. To date, two genes, GDF5 and NOG, have been reported to associate with SYM1. Herein, we clinically characterized a Chinese family
OBJECTIVE
To define the genetic basis of a family with an autosomal, dominantly inherited form of spondyloepiphyseal dysplasia (SED) associated with tall stature.
METHODS
A 6 generation family with early onset osteoarthritis (OA) associated with mild SED was studied. 14 individuals were examined
OBJECTIVE
To examine the genotypic and phenotypic characteristics of a Micronesian kindred with autosomal dominant precocious osteoarthritis (OA).
METHODS
We reviewed records and radiographs of 3 index patients and their parents, administered questionnaires to 16 additional kindred members,
BACKGROUND
Pfeiffer syndrome (PS; OMIM #101600) is an autosomal dominant disorder characterized by craniosynostosis, midface hypoplasia, broad thumbs, brachydactyly, broad great toes, and variable syndactyly.
METHODS
We report a case of PS (type 3) with tracheal and visceral involvement and
