<div class="spaceAbove">Achondroplasia is the most common cause of disproportionate short stature. 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.</div>

Recurrence of bone hyperostosis, fever, soft-tissue swelling, and pain can occur later in life. Adults with a history of Caffey disease in childhood may have joint laxity, skin hyperextensibility, hernias, short stature, and an increased risk for bone fractures and/or deformities.</div>

<div class="spaceAbove">The term achondrogenesis has been used to characterize the most severe forms of chondrodysplasia in humans, invariably lethal before or shortly after birth. 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).</div>

<div class="spaceAbove">Familial hypomagnesemia with hypercalciuria and nephrocalcinosis is a progressive renal disorder characterized by excessive urinary Ca(2+) and Mg(2+) excretion. There is progressive loss of kidney function, and in about 50% of cases, the need for renal replacement therapy arises as early as the second decade of life (summary by Muller et al., 2006). Amelogenesis imperfecta may also be present in some patients (Bardet et al., 2016).&#13; A similar disorder with renal magnesium wasting, renal failure, and nephrocalcinosis (HOMG5; 248190) is caused by mutations in another tight-junction gene, CLDN19 (610036), and is distinguished by the association of severe ocular involvement.&#13; For a discussion of phenotypic and genetic heterogeneity of familial hypomagnesemia, see HOMG1 (602014).</div>

<div class="spaceAbove">Vitamin D-dependent rickets is a disorder of bone development that leads to softening and weakening of the bones (rickets). There are several forms of the condition that are distinguished primarily by their genetic causes: type 1A (VDDR1A), type 1B (VDDR1B), and type 2A (VDDR2A). There is also evidence of a very rare form of the condition, called type 2B (VDDR2B), although not much is known about this form.\n\nThe signs and symptoms of vitamin D-dependent rickets begin within months after birth, and most are the same for all types of the condition. The weak bones often cause bone pain and delayed growth and have a tendency to fracture. When affected children begin to walk, they may develop abnormally curved (bowed) legs because the bones are too weak to bear weight. Impaired bone development also results in widening of the areas near the ends of bones where new bone forms (metaphyses), especially in the knees, wrists, and ribs. Some people with vitamin D-dependent rickets have dental abnormalities such as thin tooth enamel and frequent cavities. Poor muscle tone (hypotonia) and muscle weakness are also common in this condition, and some affected individuals develop seizures.\n\nHair loss (alopecia) can occur in VDDR2A, although not everyone with this form of the condition has alopecia. Affected individuals can have sparse or patchy hair or no hair at all on their heads. Some affected individuals are missing body hair as well.\n\nIn vitamin D-dependent rickets, there is an imbalance of certain substances in the blood. An early sign in all types of the condition is low levels of the mineral calcium (hypocalcemia), which is essential for the normal formation of bones and teeth. Affected individuals also develop high levels of a hormone involved in regulating calcium levels called parathyroid hormone (PTH), which leads to a condition called secondary hyperparathyroidism. Low levels of a mineral called phosphate (hypophosphatemia) also occur in affected individuals. Vitamin D-dependent rickets types 1 and 2 can be grouped by blood levels of a hormone called calcitriol, which is the active form of vitamin D; individuals with VDDR1A and VDDR1B have abnormally low levels of calcitriol and individuals with VDDR2A and VDDR2B have abnormally high levels.</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.</div>

<div class="spaceAbove">Short-rib thoracic dysplasia (SRTD) with or without polydactyly refers to a group of autosomal recessive skeletal ciliopathies that are characterized by a constricted thoracic cage, short ribs, shortened tubular bones, and a 'trident' appearance of the acetabular roof. SRTD encompasses Ellis-van Creveld syndrome (EVC) and the disorders previously designated as Jeune syndrome or asphyxiating thoracic dystrophy (ATD), short rib-polydactyly syndrome (SRPS), and Mainzer-Saldino syndrome (MZSDS). Polydactyly is variably present, and there is phenotypic overlap in the various forms of SRTDs, which differ by visceral malformation and metaphyseal appearance. Nonskeletal involvement can include cleft lip/palate as well as anomalies of major organs such as the brain, eye, heart, kidneys, liver, pancreas, intestines, and genitalia. Some forms of SRTD are lethal in the neonatal period due to respiratory insufficiency secondary to a severely restricted thoracic cage, whereas others are compatible with life (summary by Huber and Cormier-Daire, 2012 and Schmidts et al., 2013).&#13; There is phenotypic overlap with the cranioectodermal dysplasias (Sensenbrenner syndrome; see CED1, 218330). Patients with a clinical diagnosis of Beemer-Langer syndrome have been found to carry mutations in the IFT80 gene (611177); see SRTD2, 611263.&#13; For a discussion of genetic heterogeneity of short-rib thoracic dysplasia, see SRTD1 (208500).</div>

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.

<div class="spaceAbove">Vitamin D hydroxylation-deficient rickets type 1B (VDDR1B) is caused by a defect in vitamin D 25-hydroxylation (Molin et al., 2017). 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).</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.</div>
