The human SHOX mutation database.
ABSTRACT The human SHOX database has recently been established to provide clinicians and scientists access to a central source of information about all known SHOX mutations associated with short stature phenotypes such as idiopathic short stature, Lèri-Weill dyschondrosteosis, Langer syndrome, and Turner syndrome. So far, the database contains 29 unique intragenic mutations of the SHOX gene. These mutations were detected in a total of 39 patients from different families. Fourteen of these mutations have been found from the SHOX research group at the Institute of Human Genetics in Heidelberg, Germany; 25 mutations are from data reported in the literature. Not included in this database are complete SHOX gene deletions which represent the majority of all detectable SHOX mutations [Rappold et al., 2002]. The database is accessible via the website www.shox.uni-hd.de. It contains general information about the SHOX gene, and allows remote users to search the data and to submit new mutations to the database.

ABSTRACT: Abstract Aim: Léri-Weill dyschondrosteosis (LWD) is a mesomelic dysplasia with disproportionate short stature associated with short stature homeobox-containing gene (SHOX) haploinsufficiency. The objective of this study was to improve the diagnosis of patients with suspected LWD through molecular analysis. Methods: Twelve patients from 11 families with a clinical diagnosis of LWD were analyzed with multiplex ligation-dependent probe amplification to detect deletions and duplications of SHOX and its enhancer regions. High resolution melting and sequencing was employed to screen for mutations in SHOX coding exons. Results: The molecular-based screening strategy applied in these patients allowed detection of five SHOX deletions and two previously unreported SHOX missense mutations. Conclusion: Molecular studies confirmed the clinical diagnosis of LWD in seven out of 12 patients, which provided support for therapeutic decisions and improved genetic counseling in their families.Journal of pediatric endocrinology & metabolism: JPEM 05/2013; · 0.75 Impact Factor

ABSTRACT: Canine chondrodysplasia is a heritable defect of endochondral ossification characterized by disproportionately short limbs. It is directly linked to significant health concerns, such as intervertebral disc disease. Some human skeletal dysplasias exhibit similar disproportionate dwarfisms and are associated with mutations in the RMRP and SHOX genes. These phenotypic similarities indicated RMRP and SHOX as candidate genes in dogs. They were sequenced in three chondrodysplastic and three normal-legged breeds. Single nucleotide polymorphisms in the promoter regions of both genes and in exon 2 of SHOX were found in affected and unaffected breeds, indicating that they are not associated with canine chondrodysplasia.Animal Biotechnology 02/2008; 19(1):1-5. · 0.88 Impact Factor
