title: A recurrence of a hydrop lethal skeletal dysplasia showing similarity to Desbuquois dysplasia and a proposed new sign: the Upsilon sign.
abstract: We report on a recurrence of a lethal skeletal dysplasia with features similar to Desbuquois dysplasia (DD) to expand the phenotypic spectrum of DD-like conditions, to increase awareness of DD-like phenotypes in the differential diagnosis of prenatal onset skeletal dysplasias, and to suggest a new sign, the Upsilon sign, to aid in the differential diagnosis of skeletal dysplasias with an extra ossification centre distal to second metacarpal.
