Short Stature and Turner Skeletal Features in an 11-Year-Old Boy with a Ring Y Chromosome Missing the Short Stature Homeobox Containing Gene

We report on an 11-yr-old boy with short stature and Turner skeletal features. Chromosome analysis revealed a 46,X,r(Y)(p11.3q11.2) karyotype, and FISH analysis showed loss of the Short stature homeobox containing gene (SHOX) from the ring Y chromosome. The results are consistent with the association of SHOX haploinsufficiency with short stature and Turner skeletal features, and suggest the importance of SHOX analysis in boys with Turner-like skeletal phenotype.
