[Chromosome marker in Balkan endemic nephropathy. I].

Marker third choromosome was established in 15 patients with Balkan entemic nephropathy (BEN) by high resolutive analysis, the chromosome characterized by altered rate of band differentiation in the distal half of the long arm--shortening of the band 3q25 and faster fusion of the subbands 3q26.1 and 3q26.3, not corresponding to the stage of chromosomal contraction. The reason for the asynchronization in the band characteristic observed is admitted to be the microstructural chromosomal reconstruction--del 3q24.2.
