In the following list you will find some of the most common rare diseases related to Abnormality of the skeletal system and Short foot that can help you solving undiagnosed cases.
Brachydactyly type B (BDB) is a very rare congenital malformation characterized by hypoplasia or aplasia of the terminal parts of fingers 2 to 5, with complete absence of the fingernails.

NDPLHS is an autosomal dominant disorder characterized by developmental stagnation or regression apparent in the first years of life and manifest as loss of purposeful hand movements, loss of language, and intellectual disability. Additional features may include stereotypic movements, dystonia, gait abnormalities, sleep disturbances, and small hands and feet. The phenotype is reminiscent of Rett syndrome (RTT ) (summary by Yoo et al., 2017).

More info about BRACHYDACTYLY TYPE A2Short-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 (OMIM ).

More info about EIKEN SYNDROMESynpolydactyly (SPD), or syndactyly type II, is defined as a connection between the middle and ring fingers and fourth and fifth toes, variably associated with postaxial polydactyly in the same digits. Minor local anomalies and various metacarpal or metatarsal abnormalities may be present (summary by Merlob and Grunebaum, 1986).In some families with SPD, the foot anomalies are characterized by preaxial as well as postaxial polydactyly, and appear to be fully penetrant. The more severe features of classic SPD, involving 3/4 synpolydactyly in the hands and 4/5 synpolydactyly in the feet, also occur, but at reduced penetrance. This foot phenotype is not seen in patients with classic SPD due to HOXD13 polyalanine tract expansions (Goodman et al., 1998).Malik (2012) reviewed the syndactylies, noting that the extreme phenotypic heterogeneity observed in SPD families consists of approximately 18 clinical variants that can be 'lumped' into 3 categories: typical SPD features, minor variants, and unusual phenotypes.

More info about SYNPOLYDACTYLY TYPE 1SHOX-related short stature is a primary bone dysplasia characterized by a height that is 2 standard deviations below the corresponding mean height for a given age, sex and population group, in the absence of obvious skeletal abnormalities and other diseases and with normal developmental milestones. Patients present normal bone age with normal limbs, shortening of the extremities (significantly lower extremities-trunk and sitting height-to-height ratios), normal hGH values, normal karyotype, and Leri-Weill dyschondrosteosis-like radiological signs (e.g. triangularization of distal radial epiphyses, pyramidalization of distal carpal row, and lucency of the distal radius on the ulnar side). Mesomelic disproportions and Madelung deformity are not apparent at a young age, but may develop later in life or never.
