objective rubinstein-taybi syndrome is a rare genetic disorder with characteristic featuresincluding downward slanting palpebral fissures, broad thumbs and halluces,and mental retardation. systemic features may involve cardiac, auditory,ophthalmic, endocrine, nervous, renal and respiratory systems. this syndromeis sporadic in nature and has been linked to microdeletion at 16p 13.3 encodingcreb-...
Specific rearrangements of chromosome 16 are well known in acute nonlymphocytic leukemia with abnormal eosinophils. While mapping cosmids relative to breakpoints in chromosome 16 in leukemic cells with fluorescence in situ hybridization (FISH), we have identified three areas of extensive cross-homology between 16p and 16q. Three cosmids among 99 tested showed two large signals on the short arm ...
A patient with karyotype 46,XY,der(4) was recognized by standard cytogenetic techniques, and presented with facial features, neurological impairment and pulmonary hypertension. Multiplex ligation-dependent probe amplification (MLPA) demonstrated duplication of the subtelomeric region of chromosome 16p and deletion of the subtelomeric region of chromosome 4q, suggesting a translocation between 4...
An abnormal female infant, who survived for 10 months with almost complete trisomy 16p and monosomy of sub-band 21q22.3, is described. The chromosome anomaly was the result of an unbalanced segregation of a maternal balanced translocation t(16;21)(p11;q22.3). The partial monosomy was considered to have had little or no adverse phenotypic effect. Cases with trisomy of chromosome 16 material are ...
P artial trisomy 16p is a rare chromosomal anomaly in newborns: of the fewer than 30 carrier patients so far reported, most were born to parents with a balanced translocation involving the p arm of chromosome 16. Pure partial trisomy 16p has been reported in seven patients, three of whom (all showing behavioural problems with autistic traits) carried a tandem duplication of the (16)(p11.2–p12) ...
AIM The gene for familial cylindromatosis (CYLD) has been localised to chromosome 16q, and has recently been cloned. Loss of heterozygosity (LOH) at 16q has also been demonstrated in sporadic cylindromas. The aim of this study was to investigate whether CYLD plays a role in the development of other skin appendage tumours. METHODS A total of 55 cases of skin adnexal tumours, comprising 12 diff...
Human telomeres are composed of tandem arrays of TTAGGG repeats with many variant repeats at the proximal ends. Comparison of the interspersion of variant and TTAGGG repeats between alleles can be used to study telomere instability, but the difficulty in identifying chromosome-specific sequences close to the start of autosomal telomeres has hampered such investigations. A chromosome end, includ...
Although the occurrence of loss of genetic material in hepatocellular carcinoma (HCC) has been documented both by cytogenetic analysis and by monitoring of allelic losses, a global overview of the extent and frequency of deletion occurring throughout the genome is not yet available. To contribute to this information, DNAs extracted from flow-sorted aneuploid nuclei from HCC and matched normal D...
