β¦ Synopsis
We report on a patient with mosaic tetrasomy 8p [46,Xx147,XX+i(8p)l. The patient has 2 fused vertebrae, abnormal ribs, congenital heart defects, agenesis of corpus callosum, hypotonia, and delayed development. The patient's developmental delays are most marked in receptive and expressive language skills, with more moderate delays on cognitive, sensorimotor, and motor skill testing. These findings are similar to those of the 3 previously reported patients with mosaic i(8p).

Cytogenetic analysis of an abnormal newborn girl showed an extra chromosome with the characteristics of an isodicentric 9p chromosome [idic (9)(pter+ql&pter)] in 98% of peripheral lymphocyte metaphases examined. This cytogenetic interpretation was substantiated by quantitative measurement of erythro
Tetrasomy 9p is a rare chromosomal aberration that was described in 28 previous patients. Here we report on a newborn girl who was referred for genetic evaluation because of developmental delay, hypertonicity, microcephaly, minor anomalies, and neurometabolic findings. She had an isochromosome 9p (p
