Congenital generalized lipodystrophy type 5 (CGL5) is an autosomal recessive metabolic disorder characterized by childhood onset of lipodystrophy, severe nonalcoholic fatty liver disease, dyslipidemia, hypertriglyceridemia, low HDL, and insulin-resistant diabetes mellitus. Affected individuals also have short stature (Payne et al., 2014). For a discussion of genetic heterogeneity of congenital generalized lipodystrophy, see CGL1 (608594). [from OMIM]

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. [from OMIM]
