XLH typically manifests in the first two years of life with lower extremity bowing due to the onset of weight-bearing; however, it sometimes does not manifest until adulthood, as previously unevaluated short stature. Adults may present with calcification of the tendons, ligaments, and joint capsules, joint pain, fatigue, insufficiency fractures, and impaired mobility. Persons with XLH are prone to spontaneous dental abscesses; sensorineural hearing loss has also been reported. Rarely, individuals with XLH can suffer from spinal stenosis, Chiari I malformation, syringomyelia, and/or raised intracranial pressure." /><meta name="robots" content="index,nofollow,noarchive" />

XLH typically manifests in the first two years of life with lower extremity bowing due to the onset of weight-bearing; however, it sometimes does not manifest until adulthood, as previously unevaluated short stature. Adults may present with calcification of the tendons, ligaments, and joint capsules, joint pain, fatigue, insufficiency fractures, and impaired mobility. Persons with XLH are prone to spontaneous dental abscesses; sensorineural hearing loss has also been reported. Rarely, individuals with XLH can suffer from spinal stenosis, Chiari I malformation, syringomyelia, and/or raised intracranial pressure. [from <a title="GeneReviews" href="https://www.ncbi.nlm.nih.gov/books/NBK1116" class="defSource" target="_blank">GeneReviews</a>]</div><div class="spaceAbove"><strong>Full text of <i>GeneReview</i> (by section):</strong><br /><a class="medgenPMinfo" href="/books/NBK83985#rickets-xlh.Summary" target="NBK83985">Summary</a>  |  <a class="medgenPMinfo" href="/books/NBK83985#rickets-xlh.Diagnosis" target="NBK83985">Diagnosis</a>  |  <a class="medgenPMinfo" href="/books/NBK83985#rickets-xlh.Clinical_Characteristics" target="NBK83985">Clinical Characteristics</a>  |  <a class="medgenPMinfo" href="/books/NBK83985#rickets-xlh.Genetically_Related_Allelic" target="NBK83985">Genetically Related (Allelic) Disorders</a>  |  <a class="medgenPMinfo" href="/books/NBK83985#rickets-xlh.Differential_Diagnosis" target="NBK83985">Differential Diagnosis</a>  |  <a class="medgenPMinfo" href="/books/NBK83985#rickets-xlh.Management" target="NBK83985">Management</a>  |  <a class="medgenPMinfo" href="/books/NBK83985#rickets-xlh.Genetic_Counseling" target="NBK83985">Genetic Counseling</a>  |  <a class="medgenPMinfo" href="/books/NBK83985#rickets-xlh.Resources" target="NBK83985">Resources</a>  |  <a class="medgenPMinfo" href="/books/NBK83985#rickets-xlh.Molecular_Genetics" target="NBK83985">Molecular Genetics</a>  |  <a class="medgenPMinfo" href="/books/NBK83985#rickets-xlh.Chapter_Notes" target="NBK83985">Chapter Notes</a>  |  <a class="medgenPMinfo" href="/books/NBK83985#rickets-xlh.References" target="NBK83985">References</a></div><div class="spaceAbove"><strong>Authors:</strong><br />

<div class="portlet_content ln"><div class="mgSection"><strong>From OMIM</strong><br />X-linked dominant hypophosphatemic rickets (XLHRD), although variable in its expressivity, is characterized by rickets with bone deformities, short stature, dental anomalies, and at the biologic level, hypophosphatemia with low renal phosphate reabsorption, normal serum calcium level with hypocalciuria, normal or low serum level of vitamin D (1,25(OH)2D3, or calcitriol), normal serum level of PTH, and increased activity of serum alkaline phosphatases (summary by Gaucher et al., 2009).  <a target="_blank" href="http://www.omim.org/entry/307800">http://www.omim.org/entry/307800</a></div><div class="mgSection"><strong>From MedlinePlus Genetics</strong><br />Another rare type of the disorder is known as hereditary hypophosphatemic rickets with hypercalciuria (HHRH). In addition to hypophosphatemia, this condition is characterized by the excretion of high levels of calcium in the urine (hypercalciuria).<br /><br />Researchers have described several forms of hereditary hypophosphatemic rickets, which are distinguished by their pattern of inheritance and genetic cause. The most common form of the disorder is known as X-linked hypophosphatemic rickets (XLH). It has an X-linked dominant pattern of inheritance. X-linked recessive, autosomal dominant, and autosomal recessive forms of the disorder are much rarer.<br /><br />Other signs and symptoms of hereditary hypophosphatemic rickets can include premature fusion of the skull bones (craniosynostosis) and dental abnormalities. The disorder may also cause abnormal bone growth where ligaments and tendons attach to joints (enthesopathy). In adults, hypophosphatemia is characterized by a softening of the bones known as osteomalacia.<br /><br />In most cases, the signs and symptoms of hereditary hypophosphatemic rickets begin in early childhood. The features of the disorder vary widely, even among affected members of the same family. Mildly affected individuals may have hypophosphatemia without other signs and symptoms. More severely affected children experience slow growth and are shorter than their peers. They develop bone abnormalities that can interfere with movement and cause bone pain. The most noticeable of these abnormalities are bowed legs or knock knees. These abnormalities become apparent with weight-bearing activities such as walking. If untreated, they tend to worsen with time.<br /><br />Hereditary hypophosphatemic rickets is a disorder related to low levels of phosphate in the blood (hypophosphatemia). Phosphate is a mineral that is essential for the normal formation of bones and teeth.  <a target="_blank" href="https://medlineplus.gov/genetics/condition/hereditary-hypophosphatemic-rickets">https://medlineplus.gov/genetics/condition/hereditary-hypophosphatemic-rickets</a></div></div>

<div class="spaceAbove">Weakness of the hip girdle and upper thigh muscles, for instance in myopathies, leads to an instability of the pelvis on standing and walking. If the muscles extending the hip joint are affected, the posture in that joint becomes flexed and lumbar lordosis increases. The patients usually have difficulties standing up from a sitting position. Due to weakness in the gluteus medius muscle, the hip on the side of the swinging leg drops with each step (referred to as Trendelenburg sign). The gait appears waddling. The patients frequently attempt to counteract the dropping of the hip on the swinging side by bending the trunk towards the side which is in the stance phase (in the German language literature this is referred to as Duchenne sign). Similar gait patterns can be caused by orthopedic conditions when the origin and the insertion site of the gluteus medius muscle are closer to each other than normal, for instance due to a posttraumatic elevation of the trochanter or pseudarthrosis of the femoral neck.</div>

<div class="spaceAbove">Osteoarthritis (OA) is a degenerative disease of the joints characterized by degradation of the hyaline articular cartilage and remodeling of the subchondral bone with sclerosis (Meulenbelt et al., 2006). Clinical problems include pain and joint stiffness often leading to significant disability and joint replacement. Osteoarthritis exhibits a clear predilection for specific joints; it appears most commonly in the hip and knee joints and lumbar and cervical spine, as well as in the distal interphalangeal and the first carpometacarpal (base of thumb) and proximal interphalangeal joints of the hand; however, patients with osteoarthritis may have 1, a few, or all of these sites affected (Stefansson et al., 2003). According to a conservative estimate, greater than 70% of the population of the United States at age 65 years is affected by the disease, reflecting its age dependence.&#13; Genetic Heterogeneity of Susceptibility to Osteoarthritis&#13; Susceptibility to osteoarthritis has been associated with variation in other genes: OS2 (140600) with variation in the MATN3 gene (602109) on chromosome 2p24; OS3 (607850) with variation in the ASPN gene (608135) on chromosome 9q22; and OS5 (612400) with variation in the GDF5 gene (601146) on chromosome 20q11.&#13; Other susceptibility loci for osteoarthritis have been mapped to chromosomes 2q33 (OS4; 610839) and 3p24 (OS6; 612401).</div>

<div class="spaceAbove">Rickets is divided into two major categories including calcipenic and phosphopenic. Hypophosphatemia is described as a common manifestation of both categories. Hypophosphatemic rickets is the most common type of rickets that is characterized by low levels of serum phosphate, resistance to ultraviolet radiation or vitamin D intake. There are several issues involved in hypophosphatemic rickets such as calcium, vitamin D, phosphorus deficiencies. Moreover, other disorder can be associated with its occurrence such as absorption defects due to pancreatic, intestinal, gastric, and renal disorders and hepatobiliary disease. Symptoms are usually seen in childhood and can be varied in severity. Severe forms may be linked to bowing of the legs, poor bone growth, and short stature as well as joint and bone pain. Hypophosphatemic rickets are associated with renal excretion of phosphate, hypophosphatemia, and mineral defects in bones. The familial type of the disease is the most common type of rickets.</div>
