| Remarks |
Clinically normal; positive for fra(X) in PBL; carrier female by Southern and PCR analyses; PCR analysis shows that 1 allele has CGG repeats of 28-29 and a second allele possibly has the full mutation with greater than 200 repeats; sister of GM07536; 1 affected son and 2 affected grandsons. |
