Abstract
Spondylometaphyseal dysplasia Algerian type (MIM no.: 184253) is an uncommon autosomal dominant skeletal dysplasia caused by heterozygous mutations in the COL2A1 gene (MIM no.: 120140). In this case based review, we reported a 5-year-old boy with short stature, severe dorsolumbar scoliosis, lumbar hyperlordosis, short trunk, and severe genu valgum . Radiological examination showed platyspondyly, irregular metaphyseal radiolucencies intermingled with radiodensities, and corner fractures. The patient has a c.3275G > A; p.Gly1092Asp mutation in exon 47 of the COL2A1 gene and a variant of unknown significance in c.1366-13C > A in intron 21. This latter sequence variant could partially or completely disrupt the natural splice acceptor site of intron 21/exon 22 in the COL2A1 gene leading to a potential modification of the phenotypic severity.
期刊介绍:
The Journal of Pediatric Genetics is an English multidisciplinary peer-reviewed international journal publishing articles on all aspects of genetics in childhood and of the genetics of experimental models. These topics include clinical genetics, molecular genetics, biochemical genetics, medical genetics, dysmorphology, teratology, genetic counselling, genetic engineering, formal genetics, neuropsychiatric genetics, behavioral genetics, community genetics, cytogenetics, hereditary or syndromic cancer genetics, genetic mapping, reproductive genetics, fetal pathology and prenatal diagnosis, multiple congenital anomaly syndromes, and molecular embryology of birth defects. Journal of Pediatric Genetics provides an in-depth update on new subjects and current comprehensive coverage of the latest techniques used in the diagnosis of childhood genetics. Journal of Pediatric Genetics encourages submissions from all authors throughout the world. The following articles will be considered for publication: editorials, original and review articles, short report, rapid communications, case reports, letters to the editor, and book reviews. The aim of the journal is to share and disseminate knowledge between all disciplines in the field of pediatric genetics. This journal is a publication of the World Pediatric Society: http://www.worldpediatricsociety.org/ The Journal of Pediatric Genetics is available in print and online. Articles published ahead of print are available via the eFirst service on the Thieme E-Journals platform.
