PY - 1988 DA - 1988/06/01 TI - Acquired chromosome rearrangements in human lymphocytes: effect of aging JO - Human Genetics SP - 147 EP - 150 VL - 79 IS - 2 AB - A prospective study of structural rearrangements occurring in normal lymphocytes was carried out. For each of two newborns and four young and two old adults, about 1000 metaphases from 72-h and 120 from 48-h cultures were studied. The frequency of rearrangements between bands 7p14, 7q35, 14q11.2 or 14q12 and 14qter, which is on the average about 0.003, is higher in newborns (0.0043) than in adults (0.0024). Conversely, the rearrangements involving other bands, which have a frequency of 0.025 on the average, are more frequent in old adults (f=0.038) than in young adults (f=0.025) and newborns (f=0.013). The first type of rearrangement, which occurs in utero, may correspond to immunoglobulin and related gene rearrangements. The other rearrangements seem to accumulate progressively and may reflect exposure to mutagens. It is import to discriminate these two types of rearrangements when studying the effect of low doses of mutagens.
