We studied a familial dup(5q) present in a phenotypically normal father and his monozygotic twin daughters with different abnormal phenotypes. High-resolution chromosome analysis suggested that the duplicated segment was of region q15-21, which seems to be the smallest dup(5q) reported thus far. Thi

✦ Synopsis
Duplication of a portion of Xq has been observed in males with abnormalities. In some cases, their mothers or even grandmothers had the same duplication but did not show any phenotypic abnormalities. However, a few cases of females with a de novo Xq duplication do present some abnormalities. We describe a 16-month-old girl with short stature, motor delay with hypotonia, scoliosis, right hemiatrophy, and ptosis of the right eye, with an Xq duplication. The duplicated region is read dir dup(X)(q22.1q25). Am. J. Med. Genet. 87:302-305, 1999.

X inactivation is the process by which mammalian females achieve dosage compensation by transcriptionally silencing one X chromosome. In chromosomally normal females, this process is random. However, most females with one abnormal X chromosome demonstrate complete skewing of X inactivation, presumab
We describe a 6 1/2-year-old girl with an interstitial deletion of chromosome arm 18q (18q21.1q22.3). Her clinical manifestations are a combination of those found in monosomy 18q syndrome and those of Rett syndrome. Cytogenetic analysis demonstrated a deletion of the long arm of chromosome 18, defin
