OMIM : ⁵⁸ Spondylometaphyseal dysplasia with cone-rod dystrophy (SMDCRD) is characterized by postnatal growth deficiency resulting in profound short stature, rhizomelia with bowing of the lower extremities, platyspondyly with anterior vertebral protrusions, progressive metaphyseal irregularity and cupping with shortened tubular bones, and early-onset progressive visual impairment associated with a pigmentary maculopathy and electroretinographic evidence of cone-rod dysfunction (summary by Hoover-Fong et al., 2014). Yamamoto et al. (2014) reviewed 16 reported cases of SMDCRD, noting that all affected individuals presented uniform skeletal findings, with rhizomelia and bowed lower limbs observed in the first year of life, whereas retinal dystrophy had a more variable age of onset. There was severe disproportionate short stature, with a final height of less than 100 cm; scoliosis was usually mild. Visual loss was progressive, with stabilization in adolescence. (608940)

MalaCards based summary : Spondylometaphyseal Dysplasia with Cone-Rod Dystrophy, also known as smd-crd, is related to cone-rod dystrophy 2 and spondyloepimetaphyseal dysplasia, strudwick type. An important gene associated with Spondylometaphyseal Dysplasia with Cone-Rod Dystrophy is PCYT1A (Phosphate Cytidylyltransferase 1, Choline, Alpha), and among its related pathways/superpathways are Phosphonate and phosphinate metabolism and Glycerophospholipid metabolism. Affiliated tissues include bone and eye, and related phenotypes are bowing of the long bones and platyspondyly

NIH Rare Diseases : ⁵⁴ The following summary is from Orphanet, a European reference portal for information on rare diseases and orphan drugs.Orpha Number: 85167Disease definitionSpondylometaphyseal dysplasia-cone-rod dystrophy syndrome is characterised by the association of spondylometaphyseal dysplasia (marked by platyspondyly, shortening of the tubular bones and progressive metaphyseal irregularity and cupping), with postnatal growth retardation and progressive visual impairment due to cone-rod dystrophy. So far, it has been described in eight individuals. Transmission appears to be autosomal recessive.Visit the Orphanet disease page for more resources.
