X linked segregation observed in 3 families with 31 progeny. A 2.3 kb EcoRI fragment has been used to detect a BanII RFLP. Enzyme(s) not detecting polymorphism: ApaI, BamHI, BglII, BstEII, BstNI, CfoI, EcoRI, EcoRV, HaeIII, HindII, HindIII, HinfI, HpaII, KpnI, MspI, PstI, PvuII, RsaI, SacI, ScaI, TaqI, XbaI, XhoI, XmnI (tested against 10-12 unrelated Caucasians). |
| Comments |
Restriction digests of the clone give the following sizes (kb): BamHI--23, 9.4 (arms); 18 (insert); EcoRI--20 (arm), 13 (arm/insert), 3.2, 3.0, 2.4, 1.8/1.75 doublet. X linked segregation observed in 3 families with 31 progeny. Informative in CEPH pedigrees 21, 23, 1331, 1345, and IMR pedigree 884. A 2.3 kb EcoRI fragment has been used to detect a BanII RFLP. The 2.4 (2.3) kb EcoRI fragment is unique and detects the RFLP; other fragments contain repeats. Enzyme(s) not detecting polymorphism: ApaI, BamHI, BglII, BstEII, BstNI, CfoI, EcoRI, EcoRV, HaeIII, HindII, HindIII, HinfI, HpaII, KpnI, MspI, PstI, PvuII, RsaI, SacI, ScaI, TaqI, XbaI, XhoI, XmnI (tested against 10-12 unrelated Caucasians). |
