| Identified Mutation |
DEL; In a fetus with Langer mesomelic dysplasia (249700), Belin et al. (1998) confirmed deletion of both SHOX alleles by fluorescence in situ hybridization. The mother, who had dyschondrosteosis (127300), was found to be heterozygous at this locus. Belin et al. (1998) showed that Langer mesomelic dysplasia results from homozygous mutations at the SHOX locus. Shears et al. (1998) likewise demonstrated a role for homozygous deletion involving the SHOX gene in the etiology of Langer dysplasia.

| Remarks |
Clinically affected; anthropometric measurements at age 50 years: height = 146.7 cm, weight = 117 lbs, head circumference = 57.8 cm; curvature of forearms noted at birth; increased carrying angle; Madelung's wrist deformity; hydrocele repair; bilateral osteotomies on femurs and derotation of hips for treatment of in toeing during childhood; attention-deficit disorder diagnosed in adulthood; acid reflux; donor subject is a compound heterozygote: one allele has a complete deletion of one SHOX gene and a second allele has a deletion of DXYS233. Exon duplications or deletions were not ruled out, apart from the deletions detected by FISH with a SHOX cosmid. |
