Clinical records, autopsy reports, and microscopic slides from 11 infants with the recombinant 8 syndrome, an inherited abnormality of chromosome 8 affecting Hispanics from New Mexico and Colorado, were evaluated. A prevalence of cardiac and genitourinary anomalies was found, while few central nervous system abnormalities were observed. Dysmorphic features associated with recombinant 8 syndrome are presented, with descriptions of the inheritance pattern and recurrence risk. Because recombinant 8 syndrome is a chromosomal disorder that will appear more and more frequently as kindreds enlarge, pathologists must be alert to its diagnostic characteristics and genetic implications.
