Conditions with this feature

X-linked spondyloepimetaphyseal dysplasia
MedGen UID:
Concept ID:
Disease or Syndrome
A rare genetic primary bone dysplasia disorder with characteristics of disproportionate short stature with mesomelic short limbs, leg bowing, lumbar lordosis, brachydactyly, joint laxity and a waddling gait. Radiographs show platyspondyly with central protrusion of anterior vertebral bodies, kyphotic angulation and very short long bones with dysplastic epiphyses and flared, irregular, cupped metaphyses.
Spondyloepimetaphyseal dysplasia-short limb-abnormal calcification syndrome
MedGen UID:
Concept ID:
Disease or Syndrome
Spondyloepimetaphyseal dysplasia-short limb-abnormal calcification syndrome is a rare, genetic primary bone dysplasia disorder characterized by disproportionate short stature with shortening of upper and lower limbs, short and broad fingers with short hands, narrowed chest with rib abnormalities and pectus excavatum, abnormal chondral calcifications (incl. larynx, trachea and costal cartilages) and facial dysmorphism (frontal bossing, hypertelorism, prominent eyes, short flat nose, wide nostrils, high-arched palate, long philtrum). Platyspondyly (esp. of cervical spine) and abnormal epiphyses and metaphyses are observed on radiography. Atlantoaxial instability causing spinal compression and recurrent respiratory disease are potential complications that may result lethal.
Spondylometaphyseal dysplasia, Sedaghatian type
MedGen UID:
Concept ID:
Disease or Syndrome
Sedaghatian-type spondylometaphyseal dysplasia (SMDS) is a rare lethal disorder characterized by severe metaphyseal chondrodysplasia with mild limb shortening, platyspondyly, delayed epiphyseal ossification, irregular iliac crests, and pulmonary hemorrhage. Affected infants present with severe hypotonia and cardiorespiratory problems; most die within days of birth due to respiratory failure. Cardiac abnormalities include conduction defects, complete heart block, and structural anomalies. Half of infants with SMDS are reported to have central nervous system malformations consistent with abnormal neuronal migration, including agenesis of the corpus callosum, pronounced frontotemporal pachygyria, simplified gyral pattern, partial lissencephaly, and severe cerebellar hypoplasia (summary by Smith et al., 2014).
Spondyloepimetaphyseal dysplasia, Genevieve type
MedGen UID:
Concept ID:
Disease or Syndrome
Spondyloepiphyseal dysplasia of the Genevieve type (SEMDG) is characterized by infantile-onset severe developmental delay and skeletal dysplasia, including short stature, premature carpal ossification, platyspondyly, longitudinal metaphyseal striations, and small epiphyses (summary by van Karnebeek et al., 2016).
