Partial trisomy 11q was detected in an infant delivered 3-4 weeks prematurely. The phenotype included slanted palpebral fissures, high arched palate, developmental delay, microcephaly, and cardiac defects, all of which occur in the majority of cases with this syndrome. Other features included a column-shaped skull, preauricular pit, single palmar crease, short, broad great toes, flat occiput, unilateral kidney agenesis, and strabismus. Chromosomes obtained from peripheral blood cells revealed the presence of extra material on the long arm of chromosome 1. The G-banding pattern of this extra material indicated that it might be derived from chromosome 1 or 11. Chromosomal {open_quotes}paints{close_quotes} showed that it was not chromosome 1 material, but was chromosome 11 material extending from band q21 to qter. Partial trisomy 11q arising from translocation of the 11q material to chromosome 2, 3, 4, 5, 6, 9, 10, 13, 17, 21, 22, and X has been reported previously, whereas translocation to chromosome 1 has not. The chromosome to which the 11q material is translocated does not alter the most frequent features of the partial trisomy 11q syndrome, but may influence other less common features.
