Remarks |
Clinically affected female; X/autosome de novo balanced chromosome translocation; normal X chromosome is late replicating; at age 4 1/2 there was a normal gait, no lumbar lordosis, no Gower sign, weakness exhibited when climbing stairs, weak facial and shoulder girdle musculature; elevated CPK's ranging from 1260 to 4200; no dystrophin gene deletion or duplication detectable by PCR. |
