Mild short stature is often present. Considerable inter- and intrafamilial variability has been observed, with all or only some digits affected, and complete absence of the middle phalanx in some cases. Metacarpals may also be shortened, and clinodactyly, camptodactyly, and ulnar deviation have been reported. Some patients exhibit abnormalities of the feet (Zhu et al., 2007; Lodder et al., 2008; Byrnes et al., 2009; Vasques et al., 2018).&#13; Genetic Heterogeneity of Brachydactyly Type A1&#13; BDA1B (607004) has been mapped to chromosome 5. BDA1C (615072) is caused by mutation in the GDF5 gene (601146) on chromosome 20q11. BDA1D (616849) is caused by mutation in the BMPR1B gene (603248) on chromosome 4q22." /><meta name="robots" content="index,nofollow,noarchive" />

<div class="portlet_content ln">Brachydactyly type A1 (BDA1) is an autosomal dominant disorder characterized by shortening of the middle phalanges of the digits of the hand, with or without symphalangism. Mild short stature is often present. Considerable inter- and intrafamilial variability has been observed, with all or only some digits affected, and complete absence of the middle phalanx in some cases. Metacarpals may also be shortened, and clinodactyly, camptodactyly, and ulnar deviation have been reported. Some patients exhibit abnormalities of the feet (Zhu et al., 2007; Lodder et al., 2008; Byrnes et al., 2009; Vasques et al., 2018).&#13; Genetic Heterogeneity of Brachydactyly Type A1&#13; BDA1B (607004) has been mapped to chromosome 5. BDA1C (615072) is caused by mutation in the GDF5 gene (601146) on chromosome 20q11. BDA1D (616849) is caused by mutation in the BMPR1B gene (603248) on chromosome 4q22. [from <a title="Online Mendelian Inheritance in Man" href="http://www.omim.org" class="defSource" target="_blank">OMIM</a>]</div>

<div class="spaceAbove">Eiken syndrome (EKNS) is an autosomal recessive skeletal dysplasia characterized by delayed ossification of bones, epiphyseal dysplasia, and bone remodeling abnormalities. Type A1 brachydactyly (see 112500), supernumerary epiphyses of proximal phalanges and metacarpals, and failure of eruption of primary teeth have also been described. Defining radiologic features include delayed ossification of epiphyses and primary ossification centers of short tubular bones, modeling abnormalities of tubular bones, and angel-shaped phalanges (Jacob et al., 2019).&#13; See 603740 for a disorder with similar radiologic features.</div>

<div class="spaceAbove">A rare, genetic, congenital limb malformation syndrome characterized by bilateral thumb ankylosis, type A brachydactyly and mild to moderate intellectual disability. Patients present thumb stiffness and abnormalities of the metacarpal bones, frequently associated with mild facial dysmorphism and signs of obesity. There have been no further descriptions in the literature since 1990.</div>
