Regional chromosomal localisation of APOA2 to 1q21–1q23

摘要

Using in situ hybridisation, we have mapped APOA2 to the 1q21–1q23 region of chromosome 1. DNA hybridisation to somatic cell hybrids made from cells carrying a balanced translocation between X and 1 confirms the localisation as proximal to 1q23. This was further confirmed by the presence of two polymorphic alleles in a cell line carrying a deletion of 1q25–1
