A rare heterochromatic variant of chromosome 4

Z Docherty et al. J Med Genet. 1984 Dec.

Abstract

A variant chromosome 4 with a large G positive heterochromatic block is described and discussed in relation to chromosome 4 heteromorphisms observed with other banding techniques. The extra heterochromatin is C positive and fluoresces brilliantly with Q banding, but differs from Yqh with some methods of staining.
