Weill-Marchesani syndrome (WMS) is a connective tissue disorder characterized by abnormalities of the lens of the eye, short stature, brachydactyly, joint stiffness, and cardiovascular defects. The ocular problems, typically recognized in childhood, include microspherophakia (small spherical lens), myopia secondary to the abnormal shape of the lens, ectopia lentis (abnormal position of the lens), and glaucoma, which can lead to blindness. Height of adult males is 142-169 cm; height of adult females is 130-157 cm. Autosomal recessive WMS cannot be distinguished from autosomal dominant WMS by clinical findings alone. [from GeneReviews]

Osteoglophonic dysplasia (OGD) is characterized by rhizomelic dwarfism, nonossifying bone lesions, craniosynostosis, prominent supraorbital ridge, and depressed nasal bridge (summary by White et al., 2005). [from OMIM]

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). There is phenotypic overlap with the cranioectodermal dysplasias (Sensenbrenner syndrome; see CED1, 218330). For a discussion of genetic heterogeneity of short-rib thoracic dysplasia, see SRTD1 (208500). [from OMIM]

Spondylometaepiphyseal dysplasia, short limb-hand type is an autosomal recessive disorder with clinical and radiologic features of disproportionate short stature, platyspondyly, abnormal epiphyses and metaphyses, shortening of the lower and upper limbs, short and broad fingers, and premature calcifications. The disorder is progressive with respect to the severity of the bowing of the lower limbs and the appearance of calcifications, with some patients being wheelchair-bound from age 11 years (Bargal et al., 2009). [from OMIM]

Winchester syndrome (WNCHRS) presents with severe osteolysis in the hands and feet and generalized osteoporosis and bone thinning, similar to multicentric osteolysis, nodulosis, and arthropathy (MONA; 259600), but subcutaneous nodules are characteristically absent. Various additional features including coarse face, corneal opacities, gum hypertrophy, and EKG changes have been reported (summary by Zankl et al., 2007). Reviews Winter (1989) provided a review of Winchester syndrome. De Vos et al. (2019) reviewed Winchester syndrome, Frank-Ter Haar syndrome (249420), and MONA, tabulating the clinical features of 63 reported patients and noting significant overlap, including craniofacial malformations, reduced bone density, skeletal and cardiac anomalies, and dermal fibrosis. Because the protein products of all 3 causative genes (MMP14; SH3PXD2B, 613293; MMP2, 120360) are involved in collagen remodeling, the authors suggested grouping them together in a revised nosologic classification, designated 'defective collagen-remodeling spectrum (DECORS).' [from OMIM]

Multicentric osteolysis nodulosis and arthropathy (MONA) is a skeletal dysplasia characterized by progressive osteolysis (particularly of the carpal and tarsal bones), osteoporosis, subcutaneous nodules on the palms and soles, and progressive arthropathy (joint contractures, pain, swelling, and stiffness). Other manifestations include coarse facies, pigmented skin lesions, cardiac defects, and corneal opacities. Onset is usually between ages six months and six years (range: birth to 11 years). [from GeneReviews]

The acromesomelic dysplasias are disorders in which there is disproportionate shortening of skeletal elements, predominantly affecting the middle segments (forearms and forelegs) and distal segments (hands and feet) of the appendicular skeleton. Acromesomelic dysplasia-1 (AMD1) is characterized by severe dwarfism (height below 120 cm) with shortening of the middle and distal segments of the limbs. This condition is usually diagnosed at birth and becomes more obvious in the first 2 years of life. X-rays show short broad fingers, square flat feet, and shortening of the long bones (particularly the forearms). The radius is bowed; the ulna is shorter than the radius, and its distal end is occasionally hypoplastic. The skull is dolichocephalic and a shortness of the trunk, with decreased vertebral height and narrowing of the lumbar interpedicular distances, is consistently observed. Facial appearance and intelligence are normal (summary by Faivre et al., 2000). Genetic Heterogeneity of Acromesomelic Dysplasia Additional autosomal recessive forms of acromesomelic dysplasia include acromesomelic dysplasia-2A (200700), -2B (228900), and -2C (201250), all caused by mutation in the GDF5 gene (601146) on chromosome 20q11; AMD3 (200700), caused by mutation in the BMPR1B gene (603248) on chromosome 4q22; and AMD4 (619636), caused by mutation in the PRKG2 gene (601591) on chromosome 4q21. An autosomal dominant form of acromesomelic dysplasia has also been reported (see 112910). [from OMIM]

X-linked spondyloepimetaphyseal dysplasia (SEMDX) is characterized by anomalies of the spine and the epiphyses and metaphyses of the long bones, resulting in short stature and osteoarthritic changes of the joints. Patients with SEMDX show rhizomelic shortening of the limbs and short limb-to-trunk ratio, significant bowing of the legs, waddling gait with lumbar lordosis, and brachydactyly (Cho et al., 2016). [from OMIM]

Heyn-Sproul-Jackson syndrome (HESJAS) is characterized by microcephalic dwarfism and global developmental delay (Heyn et al., 2019). [from OMIM]

Leri pleonosteosis is an autosomal dominant skeletal disorder characterized by flexion contractures of the interphalangeal joints, limited movement of multiple joints, and short, broad metacarpals, metatarsals, and phalanges. Additional features may include chronic joint pain, short stature, bony overgrowths, spinal cord compression, scleroderma-like skin changes, and blepharophimosis. The clinical features overlap with several other musculoskeletal conditions, including Myhre syndrome (MYHRS; 139210) and geleophysic dysplasia (GPHYSD1; 231050) (summary by Banka et al., 2015). [from OMIM]

X-linked syndromic intellectual developmental disorder with pigmentary mosaicism and coarse facies (MRXSPF) is characterized by a phenotypic triad of severe developmental delay, coarse facial dysmorphisms, and Blaschkoid pigmentary mosaicism. Additional clinical features may include epilepsy, orthopedic abnormalities, hypotonia, and growth abnormalities. The disorder affects both males and females (Villegas et al., 2019; Diaz et al., 2020). [from OMIM]
