We report a baby with the features of Rieger syndrome and a de novo interstitial deletion of 4q which includes band 4q26 and an adjoining GTL light band, either q25 or q27. Rieger syndrome is provisionally mapped to 4q23----q27 but band 4q26 has been excluded as a possible site, suggesting that Rieger syndrome must map to a band, either 4q25 or 4q27, adjoining 4q26.

The translocation t(12;15)(p13;q25), in which the ETV6 gene from chromosome 12 is rearranged with the NTRK3 gene from chromosome 15, has recently been identified in secretory breast carcinoma (SBC). This fusion gene was initially described in congenital fibrosarcoma and congenital mesoblastic nephroma. The biological consequence of this translocation is the expression of a chimeric protein tyro...

Campomelic dysplasia (CMPD), a rare congenital disorder, is characterized by a variety of skeletal anomalies, low-set ears and, in nearly half of genotypical-male patients, sex reversal. Observations of chromosomal translocations involving chromosome 17q24-q25 in several CMPD patients have implied that disruption of one or more genes in the breakpoint region is responsible for this disease. Usi...

The Lake Victoria basin’s expanding population is heavily reliant on rainfall and river flow to meet their water needs, making them extremely vulnerable changes in climate land use. To develop adaptation mitigation strategies it urgently necessary evaluate the impacts of change quantity rivers that drain into Victoria. In this study, semi-distributed hydrological SWAT model was used impact curr...

A girl with a new de novo translocation of 4q onto the short arm of acrocentric 22 is reported as a case of "pure" partial trisomy 4q. Her karyotype was 46, XX,-22, +mar, t(4;22)(q25-->qter;p11) identified by Giemsa staining and FISH. Comparison of the proband with previously reported cases of "pure" partial trisomy 4q showed the main clinical features to be growth retardation, psychomotor reta...
