Molecular topography of the secondary constriction region (qh) of human chromosome 9 with an unusual euchromatic band.

American journal of human genetics - 1 May 1993

Verma R S, Luke S, Brennan J P, Mathews T, Conte R A, Macera M J

Abstract excerpt

Heterochromatin confined to pericentromeric (c) and secondary constriction (qh) regions plays a major role in morphological variation of chromosome 9, because of its size and affinity for pericentric inversion. Consequently, pairing at pachytene may lead to some disturbances between homologous chromosomes having such extreme variations and may result in abnormalities involving bands adjacent to the qh region. We...
