Affected individuals have rhizomelic shortening of the limbs, macrocephaly, and characteristic facial features with frontal bossing and midface retrusion. In infancy, hypotonia is typical, and acquisition of developmental motor milestones is often both aberrant in pattern and delayed. Intelligence and life span are usually near normal, although craniocervical junction compression increases the risk of death in infancy. Additional complications include obstructive sleep apnea, middle ear dysfunction, kyphosis, and spinal stenosis. [from <a title="GeneReviews" href="https://www.ncbi.nlm.nih.gov/books/NBK1116" class="defSource" target="_blank">GeneReviews</a>]</span><br /></p><div class="spaceAboveSmall"><div class="aux"><div class="resc"><dl class="rprtid"><dt>MedGen UID: </dt><dd>1289</dd><dt><span class="dotprefix"></span>Concept ID: </dt><dd><a href="/medgen/docs/help/#sources" target="_blank" title="Concept Unique Identifier from NLM's Unified Medical Language system (UMLS)&#10;Click for more information.">C0001080</a></dd><dt><span class="dotprefix"></span></dt><dd>Congenital Abnormality</dd></dl></div></div></div><div>

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>]</span><br /></p><div class="spaceAboveSmall"><div class="aux"><div class="resc"><dl class="rprtid"><dt>MedGen UID: </dt><dd>196551</dd><dt><span class="dotprefix"></span>Concept ID: </dt><dd><a href="/medgen/docs/help/#sources" target="_blank" title="Concept Unique Identifier from NLM's Unified Medical Language system (UMLS)&#10;Click for more information.">C0733682</a></dd><dt><span class="dotprefix"></span></dt><dd>Disease or Syndrome</dd></dl></div></div></div><div>

Males younger than age ten years may manifest only LMW proteinuria and/or hypercalciuria, which are usually asymptomatic. Thirty to 80% of affected males develop end-stage renal disease (ESRD) between ages 30 and 50 years; in some instances ESRD does not develop until the sixth decade of life or later. The disease may also be accompanied by rickets or osteomalacia, growth restriction, and short stature. Disease severity can vary within the same family. Males with Dent disease 2 (caused by pathogenic variants in OCRL) may also have mild intellectual disability, cataracts, and/or elevated muscle enzymes. Due to random X-chromosome inactivation, some female carriers may manifest hypercalciuria and, rarely, renal calculi and moderate LMW proteinuria. Females rarely develop CKD. [from <a title="GeneReviews" href="https://www.ncbi.nlm.nih.gov/books/NBK1116" class="defSource" target="_blank">GeneReviews</a>]</span><br /></p><div class="spaceAboveSmall"><div class="aux"><div class="resc"><dl class="rprtid"><dt>MedGen UID: </dt><dd>336322</dd><dt><span class="dotprefix"></span>Concept ID: </dt><dd><a href="/medgen/docs/help/#sources" target="_blank" title="Concept Unique Identifier from NLM's Unified Medical Language system (UMLS)&#10;Click for more information.">C1848336</a></dd><dt><span class="dotprefix"></span></dt><dd>Disease or Syndrome</dd></dl></div></div></div><div>

Achondrogenesis type I is a severe chondrodystrophy characterized radiographically by deficient ossification in the lumbar vertebrae and absent ossification in the sacral, pubic and ischial bones and clinically by stillbirth or early death (Maroteaux and Lamy, 1968; Langer et al., 1969). In addition to severe micromelia, there is a disproportionately large cranium due to marked edema of soft tissues.&#13; Classification of Achondrogenesis&#13; Achondrogenesis was traditionally divided into 2 types: type I (Parenti-Fraccaro) and type II (Langer-Saldino). Borochowitz et al. (1988) suggested that achondrogenesis type I of Parenti-Fraccaro should be classified into 2 distinct disorders: type IA, corresponding to the cases originally published by Houston et al. (1972) and Harris et al. (1972), and type IB (600972), corresponding to the case originally published by Fraccaro (1952). Analysis of the case reported by Parenti (1936) by Borochowitz et al. (1988) suggested the diagnosis of achondrogenesis type II, i.e., the Langer-Saldino type (200610). Type IA would be classified as lethal achondrogenesis, Houston-Harris type; type IB, lethal achondrogenesis, Fraccaro type; and type II, lethal achondrogenesis-hypochondrogenesis, Langer-Saldino type. Superti-Furga (1996) suggested that hypochondrogenesis should be considered separately from achondrogenesis type II because the phenotype can be much milder.&#13; Genetic Heterogeneity of Achondrogenesis&#13; Achondrogenesis type IB (ACG1B; 600972) is caused by mutation in the DTDST gene (606718), and achondrogenesis type II (ACG2; 200610) is caused by mutation in the COL2A1 gene (120140). [from <a title="Online Mendelian Inheritance in Man" href="http://www.omim.org" class="defSource" target="_blank">OMIM</a>]</span><br /></p><div class="spaceAboveSmall"><div class="aux"><div class="resc"><dl class="rprtid"><dt>MedGen UID: </dt><dd>78546</dd><dt><span class="dotprefix"></span>Concept ID: </dt><dd><a href="/medgen/docs/help/#sources" target="_blank" title="Concept Unique Identifier from NLM's Unified Medical Language system (UMLS)&#10;Click for more information.">C0265273</a></dd><dt><span class="dotprefix"></span></dt><dd>Congenital Abnormality</dd></dl></div></div></div><div>

Individuals with isolated CMTC have no other syndromic features, and skin lesions tend to fade or resolve. Those with classic CMTC may have accompanying hemihypoplasia with body asymmetry, skin atrophy or ulceration, other vascular malformations, and occasional ocular issues (early-onset glaucoma and/or peripheral retinal vascular attenuation) but do not have other malformations, dysmorphic features, or cognitive impairment. The most common location for the CMTC lesions is on the legs. An affected limb may also display weakness or be unusually susceptible to cold compared to an unaffected limb. In more than half of affected individuals, skin lesions will generally fade across a wide range in age (6 weeks to 26 years), most commonly in the first year of life, but may not resolve completely. [from <a title="GeneReviews" href="https://www.ncbi.nlm.nih.gov/books/NBK1116" class="defSource" target="_blank">GeneReviews</a>]</span><br /></p><div class="spaceAboveSmall"><div class="aux"><div class="resc"><dl class="rprtid"><dt>MedGen UID: </dt><dd>83381</dd><dt><span class="dotprefix"></span>Concept ID: </dt><dd><a href="/medgen/docs/help/#sources" target="_blank" title="Concept Unique Identifier from NLM's Unified Medical Language system (UMLS)&#10;Click for more information.">C0345419</a></dd><dt><span class="dotprefix"></span></dt><dd>Congenital Abnormality</dd></dl></div></div></div><div>

The major function of vitamin D is to maintain calcium and phosphate levels in the normal range to support metabolic functions, neuromuscular transmission, and bone mineralization. Disorders of vitamin D metabolism or action lead to defective bone mineralization and clinical features including intestinal malabsorption of calcium, hypocalcemia, secondary hyperparathyroidism, increased renal clearance of phosphorus, and hypophosphatemia. The combination of hypocalcemia and hypophosphatemia causes impaired mineralization of bone that results in rickets and osteomalacia (summary by Liberman and Marx, 2001).&#13; Rickets can occur because of inadequate dietary intake or sun exposure or because of genetic disorders. Vitamin D3 (cholecalciferol) is taken in the diet or synthesized in the skin from 7-dehydrocholesterol by ultraviolet irradiation. For vitamin D to be active, it needs to be converted to its active form, 1,25-dihydroxyvitamin D3. Vitamin D is transported in the blood by the vitamin D binding protein (DBP; 139200) to the liver, where vitamin D 25-hydroxylase (CYP2R1; 608713) is the key enzyme for 25-hydroxylation. Vitamin D 25(OH)D3, the major circulating form of vitamin D, is then transported to the kidney, where 25(OH)D3 is hydroxylated at the position of carbon 1 of the A ring, resulting in the active form of vitamin D, 1,25-dihydroxyvitamin D3 (1,25(OH)2D3) (summary by Christakos et al., 2010). [from <a title="Online Mendelian Inheritance in Man" href="http://www.omim.org" class="defSource" target="_blank">OMIM</a>]</span><br /></p><div class="spaceAboveSmall"><div class="aux"><div class="resc"><dl class="rprtid"><dt>MedGen UID: </dt><dd>374020</dd><dt><span class="dotprefix"></span>Concept ID: </dt><dd><a href="/medgen/docs/help/#sources" target="_blank" title="Concept Unique Identifier from NLM's Unified Medical Language system (UMLS)&#10;Click for more information.">C1838657</a></dd><dt><span class="dotprefix"></span></dt><dd>Disease or Syndrome</dd></dl></div></div></div><div>
