We report a novel case of partial trisomy 19q and concomitant partial monos
omy 21q, segregated from a maternal translocation (19;21) (q13.1;q22.3), id
entified by spectral karyotyping. Clinical examination revealed dysmorphic
features of the face and limbs, cleft palate, bilateral colobomas with asso
ciated bilateral colobomatous optic nerve cysts, hearing loss, and a cardia
c anomaly. At autopsy, the dysmorphic features and cleft palate were confir
med. The ocular histopathology is described in detail and the cardiac anoma
ly was further specified. The combination of phenotype features is diagnost
ic of the CHARGE (coloboma, heart malformation, atresia choanae, retarded g
rowth and development, and/or CNS anomalies, genital hypoplasia, ear anomal
ies and/or deafness) association. This case also has some phenotypic featur
es in common with previous cases of partial trisomy 19q. The importance of
a complete autopsy in cases with multiple congenital anomalies and/or genet
ic abnormalities is emphasized. This will allow optimal genetic counseling
and contribute to our understanding of developmental biology.
