Haploinsufficiency of SHOX on the short arm pseudoautosomal region (PAR1) leads to Leri-Weill dyschondrosteosis (LWD), and nullizygosity of SHOX results in Langer mesomelic dysplasia (LMD). Molecular defects of LWD/LMD include various microdeletions in PAR1 that involve exons and/or the putative upstream or downstream enhancer regions of SHOX, as well as several intragenic mutations. Here, we report on a Japanese male infant with mild manifestations of LMD and hitherto unreported microdeletions in PAR1. Clinical analysis revealed mesomelic short stature with various radiological findings indicative of LMD...

It is known that SHOX nullizygosity results in Langer mesomelic dysplasia (LMD) and SHOX haploinsufficiency leads to Leri-Weill dyschondrosteosis (LWDC). Here, we report on a microdeletion in the SHOX 3' region identified in a Japanese infant with LMD-compatible skeletal features and a 45,X[191]/46,X,r(X)(p22.3q24)[9] karyotype and in her mother with LWDC-compatible skeletal features and a normal 46,XX karyotype. Physical and auxological examinations revealed mesomelic appearance, ulnarly deviated hands, and borderline micrognathia in the infant, and relatively short forearms and lower legs in the mother...

We report on clinical and molecular findings in a Japanese family consisting of a male infant with SHOX nullizygosity and his four family members with SHOX haploinsufficiency. The male infant had Langer mesomelic dysplasia, the prepubertal sister had idiopathic short stature phenotype with no discernible skeletal features, the father had mild Léri-Weill dyschondrosteosis (LWDC), and the mother and the maternal grandmother had moderate LWDC. The five subjects lacked clinically recognizable short metacarpals, cubitus valgus, high arched palate, short neck, and micrognathia, as well as recurrent otitis media and hearing loss...
