Two unrelated patients were found to be mosaic for an extra chromosome 9 (46,XX/47,XX,+9). The first patient showed a prominent nose, deep set eyes, carp shaped mouth and complex congenital cardiac anomalies. She died of congestive cardiac failure at the age of 10 days.

Trisomy 9 syndrome is characterized by ''bulbous'' nose, microphthalmia, dislocated limbs, and other anomalies of skeletal, cardiac, genitourinary, and central nervous systems. With the exception of one reported case study, all surviving infants have had severe mental impairment. The prospect of sev
We describe a girl with physical anomalies, accelerated skeletal maturation, failure to thrive, and respiratory difficulties consistent with a diagnosis of Marshall-Smith syndrome (MSS). Chromosome analysis showed an inverted duplication of chromosome 2 [46,XX,inv dup(2)(q37q32) de novo] identified
We report on a female infant with partial trisomy 9p (pter→p13) and partial trisomy 14q (pter→q22) resulting from a 3:1 segregation of a maternal reciprocal translocation (9;14)(p13;q22). Both trisomy 9p and partial trisomy 14q have been described as recognized phenotypes with characteristic pattern
An 18 1/2-year-old female is described with moderately severe mental retardation, the phenotype of the trisomy 9p syndromy, and an isochromosome for the short arm of a chromosome 9, contained in an unique karyotype, 46,XX,-9,t(7q9q),+ iso 9p.
