This family contains DiGeorge syndrome critical region 6 (DGCR6) proteins (approximately 200 residues long) of a number of vertebrates. DGCR6 is a candidate for involvement in the DiGeorge syndrome pathology by playing a role in neural crest cell migration into the third and fourth pharyngeal pouches, the structures from which derive the organs affected in DiGeorge syndrome [1]. Also found in this family is the Drosophila melanogaster gonadal protein gdl.
