Haploinsufficiency of the short stature homeobox contaning SHOX gene has been shown to result in a spectrum of phenotypes ranging from Leri–Weill dyschondrosteosis (LWD) at the more severe end to SHOX-related short stature at the milder end of the spectrum. Most alterations are whole gene deletions, point mutations within the coding region, or microdeletions in its flanking sequences. Here, we present the clinical and molecular data as well as the potential molecular mechanism underlying a novel microdeletion, causing a variable SHOX-related haploinsufficiency disorder in a three-generation family. The phenotype resembles that of LWD in females, in males, however, the phenotypic expression is milder. The 15523-bp SHOX intragenic deletion, encompassing exons 3–6, was initially detected by array-CGH, followed by MLPA analysis. Sequencing of the breakpoints indicated an Alu recombination-mediated deletion (ARMD) as the potential causative mechanism. 相似文献

The relationship between breed and the risk of developing sarcoid tumours or uveitis of unknown etiology was evaluated in a retrospective study of 16242 equine cases admitted between 1975 and 1987 to the New York State College of Veterinary Medicine Large Animal Hospital, and 3198 equine tissue samples sent to the New York State Veterinary Diagnostic Laboratory between 1977 and 1987. Of 120 sarcoid cases from the Large Animal Hospital, sarcoids were twice as likely to develop in Quarter Horses (odds ratio, OR = 1.8, P less than 0.05) relative to Thoroughbreds and less than half as likely to develop in Standardbreds (OR = 0.2, P less than 0.001) relative to Thoroughbreds. Similarly, of 376 sarcoid cases from the Diagnostic Laboratory, Quarter Horses had a significantly higher risk of developing sarcoid (OR = 2.0, P less than 0.001) relative to Thoroughbreds, while Standardbreds had a significantly lower risk of developing sarcoid (OR = 0.5, P less than 0.05) relative to Thoroughbreds. In the uveitis diagnosis category, Appaloosas had a significantly higher risk of developing uveitis (OR = 6.4, P less than 0.001) relative to Thoroughbreds, while Standardbreds had a significantly lower risk of developing uveitis (OR = 0.4, P less than 0.05) relative to Thoroughbreds. 相似文献
