Deleted Yq in the sterile son of a man with a satellited Y chromosome (Yqs).
Disturbed spermatogenesis and azoospermia are reported in a man with a deleted Y chromosome. The anomalous Y chromosome appears in the karyotype as a small metacentric marker. In situ hybridisation using three different Y specific DNA probes shows that deletion at Yq11 has resulted in loss of all distal heterochromatin. The sterility of the patient indicates loss also of the azoospermia factor ...

15 صفحه اولCharacterisation of a satellited non-fluorescent Y chromosome (Y[nfqs]) by FISH.
A fetus was prenatally diagnosed as having a Y(nfqs) chromosome which was inherited from the father. With the QFQ technique, the Yqh was observed to be nonfluorescent and contained cytological satellites which were attached to the terminal long arm. The satellites were positively stained by the Ag-NOR technique suggesting that the NORs were active. A battery of DNA probes was used to characteri...
متن کاملA new case of Yq microdeletion transmitted from a normal father to two infertile sons.
During the last few years, microdeletions of the long arm of the Y chromosome, involving loci AZFa, AZFb, and AZFc, have been identified as a major cause of infertility, leading to the disruption of genes involved in spermatogenesis. These microdeletions are usually de novo mutations, but in six cases transmission from fertile fathers to infertile sons has been reported. In four cases, the tran...
