Molecular and clinical characterization of a recurrent cryptic unbalanced t(4q;18q) resulting in an 18q deletion and 4q duplication.
Recurrent constitutional non-Robertsonian translocations are very rare. We present the third instance of cryptic, unbalanced translocation between 4q and 18q. This individual had an apparently normal karyotype; however, after subtelomere fluorescence in situ hybridization (FISH), he was found to have a cryptic unbalanced translocation between 4q and 18q [ish der(18)t(4;18)(q35;q23)(4qtel+,18qte...
متن کاملLinkage of essential hypertension to chromosome 18q.
We performed a genomewide scan with 904 microsatellite markers using 120 extended Icelandic families with 490 hypertensive patients. The families were identified by cross-matching a list of hypertensive patients from the Hypertension Clinic of the University Hospital (Landspitalinn) in Iceland with a genealogy database of the entire Icelandic nation. After adding 5 markers, we found linkage to ...
متن کاملMolecular characterization of Xp chromosome deletion in a fertile cow.
A young cow of the Marchigiana breed (central Italy) with normal body conformation and external genitalia underwent routine cytogenetic analyses prior to its use for reproduction. After normal chromosome staining, only one X chromosome was observed with a normal diploid number (2n = 60) in all 200 studied cells. Subsequent cytogenetic analyses by using both CBA- and RBA-banding techniques evide...
متن کامل[A case of pseudoisodicentric chromosome 18q detected at prenatal diagnosis].
Although trisomy 18 (Edwards' syndrome) or the terminal deletion syndromes of 18p and 18q have been occasionally detected, pseudoisodicentric chromosome 18 is a very rare constitutional chromosomal abnormality. We describe a case of pseudoisodicentric chromosome 18q without mosaicism, which was confirmed from fetal cells in the amniotic fluid used for prenatal diagnosis of multiple congenital a...
متن کاملMolecular characterisation of partial chromosome 21 aneuploidies by fluorescent PCR.
Although trisomy of chromosome 21 is the most prevalent human genetic disorder, data from partial 21 aneuploidies are very scanty. Eight different partial aneuploidies for chromosome 21 were characterised by fluorescence quantitative PCR. Allelic dosage analysis was performed for each patient using 25 CHLC STRs covering the entire q arm. The length of the corresponding trisomies and monosomies ...
