A, PAR1 deletions in the SHOX downstream region. Top, Pedigrees of families A and B. LWD is exhibited by the mother and the daughter in family A and by the father and the daughter in family B. The height of each subject is expressed as an SD score. Bottom, Deletion maps of the SHOX 3′ region. In families A and B, the blackened segments represent the disomic regions, the unblackened segments depict the monosomic regions, and the striped segments indicate the dosage-unknown region in which the breakpoints should exist. The physical distance (kb) from the Xp/Yp telomere (“Tel”) is shown below the horizontal line. The results of the present study and those reported by Fukami et al. (2005) indicate that the SRO-J spans ∼40 kb in physical length and is largely similar to the SRO-W reported by Benito-Sanz et al. (2005). B, Functional analysis of the ECSs. Top, Seven ECSs (ECS1–ECS7) are identified in the SRO-J (UCSC Genome Browser). Bottom, Transcription analysis of ECS3–ECS6. A luciferase reporter construct has been created with the SV40 or the human SHOX promoter, and each ECS inserted into the 3′ region of the luciferase gene (“Luc”). Only the combination of the SHOX promoter and ECS4 has significantly increased the luciferase activity.

Results of the FISH analysis. Red signals indicate the RP13-167H21 region (thick arrows), and green signals represent DXZ1 (arrowheads) or DYZ3 (thin arrow). The RP13-167H21 region is deleted from one of the two X chromosomes of the mother and the daughter in family A. The signal for RP13-167H21 is obviously weak in one of the sex chromosomes of the father and the daughter in family B, whereas it is similar between the two X chromosomes of the mother.
