Distinct skeletal abnormalities in four girls with Shprintzen-Goldberg syndrome

Abstract

We describe 4 girls with Shprintzen-Goldberg syndrome. Skeletal abnormalities common to 3 of them include bowing of long bones (with a variable degree of progression over time), flare of the metaphyses, a large anterior fontanel with persistent patency into the second to fourth years of life, 13 pairs of ribs, distinct vertebral abnormalities which were absent neonatally but evolved by the second year of life, and progressive osteopenia.
