PPAC has an early age of onset, with most affected children presenting with disease features by the age of 8-years. The major presenting features include difficulty in walking, muscle weakness, pain, arthropathy, and skeletal deformities. [cags.org.ae]

Clinical description Most patients present the disease before the age of 8 years (the onset varies between 2 and 11 years). Typically, there are no symptoms in the newborn period. [orpha.net]

Due to its presentation with joint stiffness and finger swelling, it is frequently misdiagnosed as polyarticular juvenile idiopathic arthritis (JIA). [acrabstracts.org]

However, the exact mechanism of the disease is not clear at the present. The clinical course of the present patient is typical for the disease. [docslide.net]

• Fatigue

  The disease manifests around the age of three to eight years and progresses with symptoms of early fatigue, muscle weakness, joint swelling and stiffness. The resulting functional limitations are often described as having a waddling gait. [ncbi.nlm.nih.gov]

  Fatigue, muscle weakness, waddling gait, bowed legs and joint stiffness may be early manifestations. read more NGS/Del Dup Comprehensive Turnaround Time: Typically 1 to 2 weeks from receipt of a sample in the laboratory. [ctgt.net]

  Most individuals also presented with a chest deformity due to rib and spine involvement and they were unable to stand and extend their joints. [nature.com]

  It is characterised with arthralgia, joint contractures, bony swelling of metacarpophalangeal and interphalangeal joints and platyspondyly. [doi.org]

• Long Arm

  Homozygosity mapping using DNA pooling approach performed by El-Shanti et al. (1998) showed linkage in a 20 cM region on the long arm of chromosome 6. [cags.org.ae]

  Toour knowledge, this is the third case report of a patient withPPAC from Turkey (5,6).Initial mapping studies assigned the gene responsible forthe disease to the long arm of chromosome 6. [myslide.es]

  Initial mapping studies assigned the gene responsible for the disease to the long arm of chromosome 6. However, examination of COL10A1, which is a candidate gene in this region, did not reveal any mutations (7,8). [docslide.net]

• Osteophyte

  X-rays demonstrated joint space narrowing and osteophytes without erosions at the proximal and distal IP and MCP joints of the hands, the intercarpal joints, the glenohumeral joints, the tibiotalar joints and the intertarsal joints ( Fig. 1 ). [academic.oup.com]

  Osteophytic formations and periarticular calcifications can be seen. Figure 2. Radiographs of hands show large epiphyses and widened metaphyses of metacarpals and phalanges. Joint space is also reduced. Figure 3. [ncbi.nlm.nih.gov]

  In the mucopolysaccharidoses (MPSs) the vertebral deformities (hook-shaped vertebral bodies with inferior beaking or platyspondyly with central beaking) and progressive joint limitation are similar to those of PPD. [ncbi.nlm.nih.gov]

Therefore, follow-up periods should proceed to acquire progression and prognosis data. [journals.plos.org]

Etiology The responsible gene WISP3 (mapping to human chromosome 6q22) encodes a secreted growth regulator. Diagnostic methods Diagnosis is based on clinical and radiographic findings. Molecular testing is available on research basis. [orpha.net]

Aims of this study were to determine typical malpositions that arise during walking and to identify preventive strategies to reduce excessive joint damage. [ncbi.nlm.nih.gov]
