Summaries for Spondylometaphyseal Dysplasia, Kozlowski Type

NIH Rare Diseases : 49 Spondylometaphyseal dysplasia, Kozlowski type is a bone disease characterized by short stature involving the trunk. "Spondylo"refers to the spine (vertebrae), "metaphysis" refers to the wide part of the bone that contains the growth plate (the part of the bone that grows during childhood), and "dysplasia" means abnormal growth. It usually starts in early childhood when poor growth with uneven stature and a waddling gait with bow legs (genu varum) is noticed. Early osteoarthritis of the joints is also common. Other signs and symptoms include small hands and fingers, spine deformities, and X-ray showing short vertebra, mild metaphyseal changes, severe delay in ossification, square, short, flared iliac wings (the broadest part of the pelvic bone) and a flat and irregular hipbone.  Spondylometaphyseal dysplasia, Kozlowski type is caused by mutations in the TRPV4 gene. Inheritance is autosomal dominant. Treatment is surgical or the use of braces to align the spine. Last updated: 12/6/2016

MalaCards based summary : Spondylometaphyseal Dysplasia, Kozlowski Type, also known as jequier kozlowski skeletal dysplasia, is related to brachyolmia type 3 and metatropic dysplasia, and has symptoms including short neck, genu valgum and abnormality of epiphysis morphology. An important gene associated with Spondylometaphyseal Dysplasia, Kozlowski Type is TRPV4 (Transient Receptor Potential Cation Channel Subfamily V Member 4). Affiliated tissues include bone.

OMIM : 53 SMD Kozlowski (SMDK) is an autosomal dominant disorder characterized by significant scoliosis and mild metaphyseal abnormalities in the pelvis. The vertebrae exhibit platyspondyly and overfaced pedicles (Krakow et al., 2009). (184252)

UniProtKB/Swiss-Prot : 71 Spondylometaphyseal dysplasia Kozlowski type: A form of spondylometaphyseal dysplasia, a group of short stature disorders distinguished by abnormalities in the vertebrae and the metaphyses of the tubular bones. It is characterized by postnatal dwarfism, significant scoliosis and mild metaphyseal abnormalities in the pelvis. The vertebrae exhibit platyspondyly and overfaced pedicles.
