Children are normal at birth and they present developmental delay in walking by the age of 2, an abnormal waddling gait or deformities of the lower limb. Diagnosis is based on characteristic clinical and radiological findings Pseudoachondroplasia appears always to be caused by an autosomal dominant gene abnormality. This means that an adult with this disorder will have a 50% chance to pass this poorly functional gene on to each child. Not infrequently an individual with this disorder will be born to average statured parents Pseudoachondroplasia (PSACH) is a type of short-limbed dwarfism, deriving its name from phenotypic similarity to achondroplasia.

Two Average Height Parents (no history of dwarfism) Approximately 1 in 25,000 (0.004%) chance of a child with dominant dwarfism; Average Height parent and Parent with Achondroplasia Achondroplasia Definition Achondroplasia is the most common cause of dwarfism, or significantly abnormal short stature. Description Achondroplasia is one of a number of chondodystrophies, in which the development of cartilage, and therefore, bone is disturbed. The disorder appears in approximately one in every 10,000 births. Achondroplasia is usually. Difference between Dwarfism and Achondroplasia. Key difference: Dwarfism is defined as the condition of being a dwarf. Achondroplasia is a skeletal disorder, which is characterized by the failure of normal conversion of cartilage into bone that begins during fetal life and causes dwarfism. Achondroplasia is a form of short limbed dwarfism Pseudoachondroplasia (PSACH) (OMIM#177170) and multiple epiphyseal dysplasia (MED) are separate but overlapping osteochondrodysplasias. PSACH is a dominantly inherited disorder characterized by short-limb short stature, loose joints, and early-onset osteoarthropathy. The diagnosis is based on characteristic clinical and radiographic findings Pseudoachondroplasia (PSACH), a severe short-limb dwarfing condition, results from mutations that cause misfolding of the cartilage oligomeric matrix protein (COMP). Accumulated COMP in growth plate chondrocytes activates endoplasmic reticulum stress, leading to inflammation and chondrocyte death
I: Interpedicular distance in spine decreased A: Alteration (mutation) of FGF-3 It is different from pseudoachondroplasia which is also an autosomal dominant disorder with disproportionate dwarfism caused by mutation in COMP (Collagen Olimetric Protein) but presents with normal facies and cervical instability and also causes early osteoarthritis The average height of adults with achondroplasia is 4'0. Other relatively common genetic conditions that result in disproportionate short stature include spondyloepiphyseal dysplasia congenita (SEDc), diastrophic dysplasia, pseudoachondroplasia, hypochondroplasia, and osteogenesis imperfecta (OI). As one might expect from their names. Pseudoachondroplasia (PSACH) is an autosomal dominant skeletal dysplasia with an estimated incidence of ~1/60000 that is characterized by disproportionate short stature, brachydactyly, joint laxity, and early-onset osteoarthritis. COMP encodes the cartilage oligomeric matrix protein, which is expressed predominantly in the extracellular matrix (ECM) surrounding the cells that make up cartilage.
