title: Clinical variability of partial duplication 1q: a clinical report and literature review.
abstract: A female baby with multiple congenital malformations was born to a father previously known as a carrier of reciprocal translocation, t(1;18)(q25;p11). Her chromosome constitution was 46,XX,-18,der18,t(1;18)(q25;p11)pat, namely, partial duplication 1q25----qter. The main manifestations were: macrocephaly, hirsutism, camptodactyly, eye defects, lymphedema, and duodenal atresia. This patient illustrates the phenotype variability expected from such a large duplication of chromosome 1.
