Pseudo-trisomy 13 syndrome with upper limb shortness and radial hypoplasia

We report on a fetus with holoprosencephaly, postaxial polydactyly, multiple visceral anomalies, upper limb shortness, and radial hypoplasia with normal chromosomes. We provide a brief review of the newly delineated "pseudo-trisomy 13 syndrome." Severe limb shortness of radial hypoplasia has not been described previously in this syndrome. The present case may expand the spectrum of the pseudo-trisomy 13 syndrome, or may represent a distinct entity.
