Growth Profiles of human autosomal trisomies at midgestation

Somatic and visceral growth profiles of midgestation human fetuses with trisomy 21, 18, or 13 demonstrate that each disorder has a characteristic pattern of growth aberration. The most striking deviations are short limbs in trisomy 21, subnormal adrenal and lung weights in trisomy 18, and supranormal spleen and kidney weights in trisomy 13.
